CDF Checklist of Galapagos Marine mollusks

Diego Ruiz

Excluding the families Bulimulidae and Succineidae, 27 species of land shells were identified in the Galápagos Archipelago (Ecuador), recorded in 14 islands. Many of the species are endemic, belonging to Helicinidae (two species), Achatinellidae (two), Pupillidae (four), Vallonidae (two), Strobilopsidae (one), Pristilomatidae (two), and Euconulidae (three). The most abundant records are found in the human inhabited islands: Santa Cruz, San Cristóbal, Isabela and Floreana. None of the families or genera is exclusive to the archipelago; the only endemic subgenus is Strobilops (Nesostrobilops). The most widespread species is Gastrocopta munita, recorded from 12 islands. Only a few species are recorded as unique to a single island (e.g., Nesopupa (Infranesopupa) galapagensis). A new species of Ambrosiella (Achatinellidae) from Floreana is described: characterized by a parietal lamella in the aperture, this species is related to the Chilean insular fauna. Human inhabited islands host several exotic species of inadvertently introduced micromolluscs and slugs, and one intentional introduction (Lissachatina fulica). Although the introduced species are dominant in anthropogenic altered sectors of the islands, they have also invaded natural areas. New records extend the distribution of almost all terrestrial gastropod species in the Archipelago. Key words: Molluscs, Neritimorpha, Pulmonata, South America, Ecuador, Galápagos.

The nudibranch gastropod genus Aeolidiella Bergh, 1867 has been found to be polyphyletic. It holds an unnamed clade that was named Bulbaeolidia Carmona, Pola, Gosliner & Cervera, 2013. This genus is composed by four species, two of them unnamed: Bulbae-olidia alba, from Japan, Malaysia and Philippines, Bulbaeolidia japonica, from Japan, Bul-baeolidia sp. B, from Hawaii, and Bulbaeolidia sp. A, from Brazil. Bulbaeolidia was described in the context of a molecular phylogeny, thus, no " taxonomic action " regarding to the unnamed species was taken, leaving the work incomplete, and the 50 % of the members of Bulbaeolidia undescribed. In this paper we describe the Western Atlantic member of the genus Bulbaeolidia and a Pacific species from Galapagos, both cryptic with Bul-baeolidia alba (Risbec, 1929).

This Checklist of Galapagos Marine Crustaceans includes a total of all 555 taxa reported from the Galapagos Islands. For each name, detailed information is provided: its Galapagos distribution in islands groups or bioregions generated from the specimen records, comments about the taxonomy (especially synonyms), the origin (native and introduced), taxon status (accepted vs. rejected records) and relevant literature references.

Molluscs are a large group of animals presenting bilateral symmetry (sometimes secondary), with soft unsegmented bodies which in most species are protected by a shell. Although marine mollusks represent one of the best studied and largest group of marine invertebrates it is still not known for the majority of species whether these are native to the archipelago or if they were introduced (see below: origin of the taxa included in this checklist). For marine species distribution data cited in the CDF Galapagos Checklists refer to the five main bioregions of the archipelago (Far Northern, Northern, Western, South Eastern and the Elithabeth Bay Bioregion). For the terrestrial species the more than 120 islands, islets and small rocks have been aggregated into Islands Groups, thus, for example, the island group “Santa Cruz” includes smaller islands like Santa Fé, Plaza Norte, Plaza Sur, Baltra, Daphne Mayor, Daphne Minor, and others. Please be aware that the distribution data presented here is automatically generated from specimen records and does not always accurately reflect the known distribution for all species. IUCN red-list assessments presented here may deviate from the global IUCN list for the following reasons: - for well known species groups like vascular plants or vertebrates updates proposed to the IUCN are shown instead of the outdated, but currently accepted status; - for poorly known species groups (e.g., lichenized fungi) a general assessment is currently not possible and the list presented here is a regional red-list list for Galapagos archipelago. Names of taxa included in this checklist: 1154 (883 Accepted , 31 Unidentified Taxon , 200 Doubtful , 2 Problematic , 1 New to Science), 37 rejected.

Acanthinucella lugubris (Sowerby, 1822) Taxon status: The identification of this taxon or its occurrence in Galapagos is doubtful. Finet (2001): Although it is mentioned in Keen (1971), the occurrence of this species in the Galapagos seems doubtful. Only one lot is recorded from the Galapagos Isl. in the CAS collection (CAS 259, ex Oldroyd), but an inaccurate locality of anything this old in the CAS collection may be dubious (see also Finet, 1985 1994, and Kaiser, 1997: 53). Galapagos Distribution: Unknown. References: Finet, Y. et al. (1985), Finet, Y. et al. (1994), Finet, Y. et al. (2001), Kaiser, K.L. et al. (1997), Keen, A.M. et al. (1971). 4.

References: Finet, Y. et al. (2001). 5. Acanthochitona cf. avicula (Carpenter, 1866) Taxon status: The identification of this taxon or its occurrence in Galapagos is doubtful. Finet (2001): Specimens of a possible new species from the Galapagos were referred provisionally to Acanthochitona avicula (Smith Ferreira, 1977). This is the reason why this species was listed among the species of verified occurrence in Finet (1985), Skoglund (1989), Finet (1991 and 1994). Kaiser (1997: 47) has rejected A. avicula from the Galápagos fauna, referring to Watters (1990), as avicula does not seem to occur south of the tip of Lower California. Galapagos Distribution: Unknown. References: Finet, Y. et al. (1985), Finet, Y. et al. (1991), Finet, Y. et al. (1994), Finet, Y. et al. (2001), Kaiser, K.L. et al. (1997), Skoglund, C. et al.

USNM: 59575; Finet (2001): According to Smith Ferreira (1977), the occurrence of this species in the Galapagos is questionable: “Stearns reported this large South American chiton from the Galapagos 2 2011 CDF Checklist of Galapagos Marine mollusks Islands based on a specimen in the U.S. National Museum under the name Acanthochiton spinifera (USNM 59575)”. ... “Dall included the Galapagos Islands in citing its range, which extends from Paita, Peru, to Valparaiso, Chile, on the mainland. Pilsbry also includes the Galapagos group for this species based on specimens in the collections of the Academy of Natural Sciences of Philadelphia”. “This conspicuous chiton” ... “can hardly be mistaken for any other species. It was not collected by Snodgrass and Heller during the Hopkins-Stanford Expedition of 1898-1899, nor by Ochsner during the 1905-1906 California Academy Expedition. No specimens were collected in Galapagos in 1964 by the senior author, or the local collectors. Why the species has not been collected in the Galapagos Islands in recent years is a mystery. Inclusion of Acanthopleura echinatum in the permanent chiton fauna of the Galapagos Islands is therefore withheld pending its possible re-discovery” (Smith Ferreira, 1977). The question was also discussed in Finet (1985 and 1994). The species was quoted again from Galápagos by Aalamo Valdivieso (1987) in their “Lista sistematica de moluscos marinos del Peru”, but Kaiser (1987: 47) includes it in her list of species of rejected occurrence.

LACM 72-196 LACM-AHF 438), but identification has not been verified and may be erroneous (see also Finet, 1994). Other material from Galápagos in LACM is mentioned by Kaiser (1997: 51): LACM 34-263, 34-262, + 46 other lots. Otherwise, oldroydae may prove to be a synonym of inconspicua C.B.

Anomia adamas Gray, 1850 Taxon status: The identification of this taxon or its occurrence in Galapagos is doubtful. BMNH: 1964538 (remaining syntype, from “Lord Hood’s Isl., Galapagos”) ?; Finet (2001): Although it was originally described from “Lord Hood’s Island, Galapagos”, and subsequently cited from the same place in old literature, we are unable to confirm the occurrence of the species in the Galapagos Archipelago. There may also have been a confusion about type locality between Hood (= Española) Isl. in the Galapagos, and Lord Hood Island in the Central Pacific. It may also be a synonym of Anomia peruviana d’Orbigny, 1846; Keen (1971) lists A. adamas as a valid species, but admits that it can be “possibly only a color form of A. peruviana, with which some authors synonymize it.” (see also Gemmell et al., 1987: 28-29).

Syn.: Anomia adamas Gray, 1850; Finet (2001): No material from the Galapagos could be examined by the author to verify the occurrence of the species. As Anomia adamas Gray, 1850 is a possible synonym of A. peruviana (see Keen, 1971: 101; Gemmell et al., 1987: 28-29), records mentioning A. adamas from the Galapagos may have to be listed with those of A. peruviana.

Arene ferruginosa McLean, 1970 Taxon status: Accepted name; taxon occurs in Galapagos. Finet (2001): Type locality of Arene ferruginosa is not Galápagos. However, in his paper with the original description of the species, McLean (1970: 123) referred also to 3 specimens from the Galápagos collected by the Allan Hancock expedition (AHF station 430, in 150 fathoms at Wenman Island). On the basis of this record, the occurrence of the species in the Archipelago was subsequently repeated by McLean in Keen (1971 : “dwarf specimens have been taken off the Galápagos Islands...”), and by Finet (1985; 1991; 1994) and Kaiser (1993). But the specimens from AHF station 430 are juveniles not easily identifiable; actually, they proved not to pertain to the species A. ferruginosa, as they were later redetermined by McLean (in litt., 1995) as Arene echinata (now LACM 34-264.2: two specimens) and Arene guttata (now LACM 34-264.3: one specimen), respectively. Actually, there seems to be no other available record to document the occurrence of Arene ferruginosa in the Galápagos, which is thus better listed as a species with a dubious occurrence.

Cancellaria chrysostoma Sowerby, 1832 Taxon status: The identification of this taxon or its occurrence in Galapagos is doubtful. AMNH: 12803, USNM: ? 56028 (identification not verified). Finet (2001): Carpenter (1857) and Stearns (1893) were the only authors to mention the species from the Galapagos in old literature. The specimen n° 12803 in the AMNH: (“Galapagos Isl., ex Haines collection”) may have an erroneous locality, as anything this old from a private collection does not necessarily have reliable data. The identification of the lot USNM: 56028 (“Galapagos Isl., ex W.H. Dall”), also old and without accurate data, was not verified. On the other hand, the material recorded from the Galapagos in the LACM: (nrs. AHF 82-33, AHF 177-34, AHF 785-38, plus several other specimens) was misidentified as Cancellaria chrysostoma Sowerby, 1832, but is Cancellaria haemastoma Sowerby, 1832. This leads me to suspect all records of C. chrysostoma from the Galapagos to be based upon erroneous localities or misidentifications, in which case the occurrence of the species in the Archipelago would be spurious or at least dubious.

The species was subsequently reported (as doubtful) from the Galápagos by Keen (1971), noting that “records from the Galápagos probably represent misidentifications”. BERNARD (1974, 1983) and Skoglund (1991) state that the distribution of the species (28° N - 60° N) is north of the Panamic Province, which would mean that all other records, including those from the Galápagos, are probably spurious.

However, C. perforans is a Californian species. The Panamic form of C. perforans, as well as the specimens from the Galapagos, are probably a situs or environmental expression of Crepidula striolata Menke, 1851, and not the true Crepidula perforans (Keen, 1971; Hoagland, pers. comm.).

Müller (1836), Carpenter (1835), Stearns (1893), Metivier (1968), Finet (1991) and Skoglund (1992) also recorded the species from the Galapagos, sometimes considering pica as a variety of D. inaequalis (Sowerby) (Carpenter, 1857: 360; Stearns, 1893; Metivier, 1968). Actually, both species are separate, but specimens of Diodora inaequalis were sometimes misidentified as Diodora pica in museum collections, and records of pica from the Galapagos may have been based upon such misidentifications (see also Finet, 1994).

Fissurella longifissa Sowerby, 1863 Taxon status: Accepted name; taxon occurs in Galapagos. Finet (2001): Reported from the Galapagos by Metivier (1968); the syntypes, from the Cuming collection (BMNH n° 1966388) are of uncertain locality: “Peru or Galapagos or Nicaragua”; Sowerby (1866, Thes. Conch. III : pl. IV, fig. 66) gave no locality in his description; Pilsbry (in Tryon, 1890) says “Habitat unknown” but gives a description based on a specimen from the Galapagos; later on, Pilsbry Vanatta (1902) also cite the Galapagos (Tagus Cove and Point Christopher, Isabela Isl.) as locality for longifissa , considering that it is a color form and thus a synonym of Fissurella macrotrema Sowerby, 1835, the latter species being furthermore synonymized in their paper with Fissurella obscura Sowerby, 1835. The examination of the type specimens of Fissurella longifissa (Finet, 1994) shows that the species seems more closely related to Fissurella obscura than to F. macrotrema or virescens; although being eroded beach 63 2011 CDF Checklist of Galapagos Marine mollusks specimens, the syntypes of longifissa show form and colour patterns resembling those of obscura (see Finet, 1994). Fissurella obscura is supposed to be endemic to the Galapagos, while F. longifissa is known from the mainland between Central America and northern Peru. Whether both taxa are valid and separate, or represent different morphs or environmental expressions of the same species (in this case, longifissa would be a junior synonym of obscura) remains a question for further research. The question was also discussed in Finet, 1994. Galapagos Distribution: Unknown. References: Finet, Y. et al. (1994), Finet, Y. et al. (1994), Finet, Y. et al. (2001), Keen, A.M. et al.

Syn.: Fissurella macrotrema Sowerby, 1835, F. nigropunctata Sowerby, 1835, Megatebennus cokeri Dall, 1909; AMNH: 20071, 20074, ANSP: 39231, 39234, LACM: n° A.6186.52a, BMNH: 1966387 (Syntypes of Fissurella nigropunctata Sowerby, 1835, type locality: Galapagos). Although having been mentioned by so many authors as occurring in the Galapagos, it seems that neither Fissurella virescens Sowerby, nor the form nigropunctata Sowerby (a synonym), nor macrotrema Sowerby (another synonym) actually occur in the Galapagos. The type locality indicated for Fissurella nigropunctata, showing black crests on the radial ribs, is “Galapagos Isl., and Lobos Isl., under stones on shore”. If it holds true for Lobos Isl. (Peru), the “Galapagos” locality is probably spurious. The only other records of virescens - nigropuncata from the “Galapagos” are in old collections of some museums, without accurate or reliable data, and are therefore dubious (AMNH 20071 20074, ex private collection; ANSP 39231 39234, ex J.S. Phillips Fund; LACM A.6186.52a, ex Ball collection). No other specimens collected in the Galapagos are known. As for Fissurella macrotrema, the original series of 11 syntypes (BMNH 1966384) was mounted separately in 3 lots, corresponding to the 3 unnamed varieties described by Sowerby from 3 different localities, one of them being the Galapagos (Finet, 1994). The syntypes were not all conspecific, but designation of a lectotype for macrotrema (Finet, 1994) makes it a synonym of F. virescens, with Lobos Isl. as type locality; other conspecific paralectotypes were described as a variety from Lambeyeque. The variety described from the Galapagos (one lot of 3 specimens) was redetermined as F. obscura Sowerby, a true Galapagan species distinct from Fissurella virescens (see Finet, 1994, 1995). The specimen from the Galapagos figured as Fissurella macrotrema by McLean in Keen (1971: fig. 36) (LACM-AHF 178-34) has been tentatively redetermined by McLean (in litt., 1993) as Fissurella cf. obscura (see Finet, 1994). Other specimens from the 64 2011 CDF Checklist of Galapagos Marine mollusks Galapagos previously identified as F. macrotrema in museum collections have now also been reidentified (LACM: F. obscura, several specimens; USNM 122129: is Fissurella deroyae Mc Lean, 1970). In my opinion, all the foregoing citations of F. virescens, nigropunctata or macrotrema from the Galapagos were based on the original type locality errors being repeated from one author to another, compounded by misidentifications of specimens in museum collections. But there seems to be no further trace of the species on the rocky shores of the Galapagos, and its occurrence there is to be considered spurious or at least dubious.

Lithophaga calyculata (Carpenter, 1857) Taxon status: The identification of this taxon or its occurrence in Galapagos is doubtful. Finet (2001): Although this species was repeatedly cited from the Galapagos by the authors mentioned above, no verified material available to us has confirmed its occurrence in the Archipelago. Some records may be based upon misidentifications of Lithophaga aristata (Dillwyn) or of other species, as noted by Olsson (1961): “An unpublished figure of Lithophagus calyculatus, prepared by Carpenter from the type, is that of a shell closely similar to L. aristata if not identical with it. The shells figured by Soot-Ryen as L. calyculata from the Mexican coast probably represent another species”. Bernard et al. (1991) however refer to the collections of the California Academy of Sciences of San Francisco to document their listing of the species with the fauna of the Galapagos, but without specifying a particular registered lot or a precise locality. Kaiser (1997) listed the species on the basis of that record by Bernard et al. (1991). So there is a good chance that L. calyculata is actually present in the Galapagos, but as many identifications referring to this species have been erroneous in the past, it seems safer to keep it provisionally in the waiting list, until identification of the CAS material or other specimens from Galapagos is confirmed.

Lottia mesoleuca (Menke, 1851) Taxon status: The identification of this taxon or its occurrence in Galapagos is doubtful. 82 2011 CDF Checklist of Galapagos Marine mollusks Finet (2001): Acmaea mesoleuca was originally described from Mazatlan, Mexico, but Reeve (1855, Conch. Icon., Patella , pl. 33, fig. 99 (not 58)) figured a specimen under the name Patella striata (as of Quoy Gaimard, but quite distinct from their species), reporting it from the Galapagos Islands (Cuming). Subsequently, Carpenter (1857: 187, 360) and Stearns (1893) cited also from the Galapagos this Patella striata of Reeve, 1855 (non Quoy Gaimard, 1834), synonym of Acmaea mesoleuca Menke. Hertlein (1937) confounded Patella striata Reeve and Acmaea striata Quoy Gaimard when he cited the latter species from both the Indo-Pacific region and the Western Americas, including the Galapagos. Lottia mesoleuca was aslo reported from the Galapagos in subsequent publications by Dall (1909), Tomlin (1927), Mc Lean in Keen (1971), Lindberg Mc Lean (1981), von Cosel (1984), Finet (1985, as of doubtful occurrence), Skoglund (1992, also as of doubtful occurrence) and Emerson (1995, idem); the species was sometimes referred to Scurria, a genus now considered to be restricted to the west coast of South America (Lindberg, 1988). A few specimens of Scurria mesoleuca (Menke, 1851) quoted from the Galapagos are present in the collections examined, but their origin may be uncertain. A single specimen has poor data on its label: “Galapagos Is. J.S. Phillips Fund” (ANSP 39189), and the locality of anything this old in the collection of the ANSP may be questionable (Robertson, pers. comm.). Two other lots in the LACM are reported from Darwin Bay, Tower (Genovesa) Island, Galapagos: LACM HH-885 (ex Howard Hill collection) and LACM-AHF 782-38 (A. Hancock Expedition, 1938); the locality of both lots may be erroneous (Mc Lean, pers. comm.), or it may be conceivable that the species is occurring only in the northern part of the Galapagos, as Genovesa is the most northeastern island of the Archipelago; this remains a question for further field research. The question was also discussed in Finet (1985 and 1994). Galapagos Distribution: Unknown. References: Carpenter, P.P. et al. (1857), Cosel, R. von et al. (1984), Dall, W.H. et al.

Mitra muricata (Broderip, 1836) Taxon status: The identification of this taxon or its occurrence in Galapagos is doubtful. Syn.: Mitra marshalli Bartsch, 1931. Finet (2001): Mitra muricata Broderip was cited from the Galapagos by Broderip (1836; original description), Carpenter (1857), Keen (1971), and Finet (1985, but as a species with a doubtful occurrence). The type locality “Galapagos Islands” given by Broderip is probably erroneous; furthermore, the board on which the syntypes were glued (BMNH: 1967610, lectotype + 2 paralectotypes) shows “California” as locality. Further and more recent records from the Galapagos may be based upon misidentifications of Mitra gausapata Reeve, 1845. Cernohorsky (1976) already came to the same conclusion: “Keen (1971) reports the species from the Galapagos Islands, but the specimens we have seen from that locality were the related species M. gausapata Reeve. The type locality “Galapagos Islands” is somewhat suspect, since the original label accompanying the type-specimens of M. muricata reads “California”. As for Mitra marshalli Bartsch, 1931, now considered a synonym of Mitra muricata (Broderip, 1836), specimens are recorded from the Galapagos Islands under this name in the collections of the LACM: (nrs. AHF 25-33 AHF 341-35), but they appear to be misidentified specimens of Mitra crenata Broderip, 1836 (see Finet, 1994). However, Kaiser (1997: 54) still mentions other material labeled as Mitra marshalli in LACM: (nrs. 33-25 34-215) and said to come from Galapagos. Galapagos Distribution: Unknown.

The true N. nodicinctus probably does not occur in the Galapagos. Accordingly, the Galapagos citations must be considered as of Nassarius nodicinctus (A. Adams, auct., non A. Adams, 1852). But we must also admit that the original locality information of “Galapagos Islands” for the syntypes of the true N. nodicinctus described by A. Adams from the H. Cuming collection is incorrect.

Type locality: Galapagos; Finet (2001): Although the species was described, then cited from the Galapagos Islands in the literature, these records are likely spurious, as explained by Nesbitt Pitt (1986): “Powys (1835) described Nassa nodifera from the Cuming collection, with the locality records “Galapagos Islands and beaches of Panama”. This locality information was copied by Reeve (1853: 23), Carpenter (1857: 361), Stearns (1893: 406), and Keen (1958: 410). Tryon (1882: 28) synonymized the species with N. hirtus (Kiener), and stated that the “localities of Panama and Galapagos are almost certainly incorrect”. This species is common in the western Pacific and the Indian Ocean, and has not been recorded subsequently from the Galapagos Islands”. This question was also discussed in Finet (1994) (species listed as “Nassarius nodiferus”). Galapagos Distribution: Unknown. References: Carpenter, P.P. et al. (1857), Carpenter, P.P. et al.

Finet (2001): Nassarius taeniolatus (Philippi, 1845) is probably a synonym of N. gayii (Kiener, 1834), from Chile (Cernohorsky, 1975; Skoglund, 1992); LACM: AHF 410, AHF 440, AHF 449, AHF 149-34, AHF 157-34, AHF 177-34, AHF 193-34, AHF 329-35 (all as N. taeniolatus), MHNG: 993-153 (as N. taeniolatus), CAS: 23157 (as N. taeniolatus) IUCN Red List: Not Evaluated.

Nassarius pagodus (Reeve, 1844) Taxon status: The identification of this taxon or its occurrence in Galapagos is doubtful. Syn.: Nassa angulifera A. Adams, 1852: type locality: Galapagos; Finet (2001): Although Nassa angulifera A. Adams was originally described from the Galapagos on the basis of material collected by H. Cuming, and although the record was repeated later by several authors, it is considered spurious by Nesbitt Pitt (1986): “The erroneous locality record probably has the same source as that for the type specimens of N. nodicinctus ... We cannot locate the specimens reported by Pilsbry Vanatta (1902) to be in the Stanford University collection, but other specimens labeled N. anguliferus from early CAS and Stanford collections are N. nodicinctus” (as described in Nesbitt Pitt, 1986). Nassarius anguliferus (A. Adams, 1852) had been synonymized with the Panamic species Nassarius pagodus (Reeve, 1844) by Tryon (1882), and this has been confirmed by Nesbitt Pitt (1986): “Thus, the spurious account of N. pagodus from the Galapagos is the result of Tryon’s synonymy. Tomlin’s (1932) synonymy of N. anguliferus with the Mediterranean species of N. miga (Bruguière) and Keen’s (1971) with N. dentifer (Powys) from the Peruvian Province are therefore 95 2011 CDF Checklist of Galapagos Marine mollusks incorrect”. The question was also discussed in Finet (1994).

Pitar tomeanus (Dall, 1902) Taxon status: The identification of this taxon or its occurrence in Galapagos is doubtful. 109 2011 CDF Checklist of Galapagos Marine mollusks Finet (2001): Although the species was described from Chile, Dall (1902), in his original description, mentioned also the Galapagos (with a question mark ?) within the range of the species; its record from the Galapagos was then repeated again by Dall (1909) and by Soot-Ryen (1932). The record is probably spurious or at least dubious. On the other hand, it must be noted that part of Pitaria tomeana auct., non Dall, 1902 is probably another species: Pitar catharius (Dall, 1902) (see Bernard, 1983); Bernard et al. (1991) listed Pitar catharius (Dall) among the Galapagos bivalves, and this species is now considered as having a verified occurrence in the Archipelago. Galapagos Distribution: Unknown.

Placiphorella blainvillii (Broderip, 1832) Taxon status: The identification of this taxon or its occurrence in Galapagos is doubtful. Finet (2001): Was mentioned from the Galapagos by Dall (1909). According to Smith Ferreira (1977), the occurrence of this species in the Galapagos is questionable: “The type locality is in 17 fathoms (31 m), Inner Lobos Island, Peru, a “few specimens... while dredging”, collected by Hugh Cuming. The United States National Museum mollusk collection contains no specimen from the Galapagos Islands, although it does have one (USNM 122968) dredged by the USS Albatross in 120 m, off Cocos Island, Costa Rica (USFC Sta. 3368). Dall’s record for Placiphorella blainvillii, from “Galapagos, Cocos and Lobos Islands”, appears as the only one published. Since there are no museum lots to substantiate the presence of P. blainvillii in the Galapagos group, the record remains in need of confirmation” (Smith Ferreira, 1977). Also according to Skoglund (1989: 86) and Clark (1994: 303), its presence in deep water off the Galapagos has not been reconfirmed since first published. Galapagos Distribution: Unknown.

Polinices galapagosus (Récluz, 1844) Taxon status: The identification of this taxon or its occurrence in Galapagos is doubtful. Type locality: Galapagos; Finet (2001): According to Marincovich (1977), this species ia a synonym of Polinices (P.) otis (Broderip Sowerby, 1829) and is not occurring in the Galapagos: “The syntypes of P. galapagosus (figured in Keen, 1971) are considered here to be specimens of P. (P.) otis. Because P. (P.) otis is not known to occur in the Galapagos, the locality data with the syntypes are probably in error. All literature illustrations of P. galapagosus known to me show specimens of P. (P.) otis. Galapagos records might be based on specimens of P. (P.) intemeratus (Philippi, 1851), as this species is found there and is often misidentified in collections as P. (P.) otis”. This question was also discussed in Finet (1985 1994). The species was quoted again from Galápagos by Alamo Valdivieso (1987) in their “Lista sistematica de moluscos marinos del Peru”, but Kaiser (1997: 52) includes it in her list of species of rejected occurrence.

Strombina paenoblita Jung, 1989 Taxon status: The identification of this taxon or its occurrence in Galapagos is doubtful. Finet (2001): This species, distinguished from the similar Strombina lanceolata (Sowerby, 1832) by Jung (1989), is not thought to occur with certainty in the Galapagos. Three specimens of the original type series of Strombina lanceolata were not recognized conspecific with the other specimens of the series, and were reidentified as Strombina paenoblita (see Jung, 1989). The locality data accompanying the type lots of S. lanceolata, all originally from the Cuming collection, was simply “Galapagos Islands”. Other material previously identified as S. lanceolata, and now reidentified as S. paenoblita (see Jung, 1989: 141) has been quoted from the Galapagos Islands; but many of the lots concerned are from older collections, and their locality data are often inaccurate and not necessarily reliable (AMNH 10373; ANSP 10290, 246579; MCZ 151412, 151414, 295265; fide Jung, 1989: 141). According to Jung (1989), “This does not mean, however, that Strombina paenoblita does not occur in the Galapagos Islands. But until more reliable information becomes available, it is thought best to leave this question open”. This question was also discussed in Finet (1994). Galapagos Distribution: Unknown.

Finet (2001): specimens from the Galapagos were often referred to this species prior to the description of Subcancilla edithrexae by Sphon (1976); actually, some of these specimens may be the new S. edithrexae, as for example the specimens from “Barrington Isl., 5-10 fms.” cited by Cernohorsky (1991: 70), which are now labelled paratypes of edithrexae (AMNH: 111069) (Emerson, pers. comm.). On the other hand, as both species are hard to tell apart on shell characters only, and as no comparison between them was made by Sphon (1976) in his description of edithrexae, whether edithrexae is a valid species endemic to the Galapagos, or a local form and thus a synonym of erythrogramma, remains a question for further research. This question was also stated by Cernohorsky (1991): “The close resemblance of “Ziba” erythrogramma and Z. edithrexae may present difficulties in identification and it remains to be ascertained whether all “erythrogramma” type of shells on the Galapagos Islands are edithrexae or whether both species live there.” 127 2011 CDF Checklist of Galapagos Marine mollusks Galapagos Distribution: Unknown.

Subcancilla sulcata (Swainson in Sowerby, 1825) Taxon status: The identification of this taxon or its occurrence in Galapagos is doubtful. Finet (2001): Although the species was mentioned from the Galapagos by Finet (1985), the record was based on one lot (LACM: n° D-88) of misidentified specimens of Mitra sphoni Shasky Campbell, and it was deleted from the faunal list in Finet (1991). Cernohorsky (1991) also included the Galapagos within the distribution range of sulcata, but this was apparently supported only by a record from a private collection (coll. Eker). Another lot is (mis)identified as Subcancilla sulcata in the collections of the Darwin Station (CDRS: n° 577), as it probably pertains to the species Subcancilla edithrexae. We consider thus that the occurrence of Subcancilla sulcata in the Galapagos is not really verified and must provisionally be considered doubtful. Galapagos Distribution: Santiago, Unknown.

Finet (2001): Was listed from the Galápagos by Bernard (1983), and Bernard et al. (1991), and by Finet (1985) as a species with a doubtful occurrence. It was assumed by Finet (1994b) that those citations might refer to Tellina brevirostris Deshayes, 1855, a species then listed as of verified occurrence (see also Myers et al., 1983, as well as Skoglund, 1991). Tellina brevirostris Deshayes was also listed by Finet (1985), but as of doubtful occurrence, and is not listed in Bernard et al. (1991). Whether the Galapagos species is really the brevirostris of Deshayes, 1855, or a brevirostris Deshayes auctt., which actually might be the reclusa of Dall, 1900, remains to be ascertained. It might also be conceivable that both species occur in Galapagos. Galapagos Distribution: Unknown. References: Bernard, F.R. et al. (1983), Bernard, F.R. et al. (1991), Finet, Y. et al.

Terebra elata Hinds, 1844 Taxon status: The identification of this taxon or its occurrence in Galapagos is doubtful. Finet (2001): This species is cited from the Galapagos by Bratcher Burch in Keen (1971), where it is also considered a synonym of Terebra guayaquilensis E.A. Smith, 1880. Actually, the two forms of Terebra elata figured in Keen (1971) belong to two separate valid species (Bratcher, 1979). The true T. elata does not seem to occur in the Galapagos, and the previous records of “T. elata” from the Galapagos all seem to refer to T. guayaquilensis (Bratcher, pers. comm., 1983). The question was also discussed in Finet (1985 1994). Galapagos Distribution: Unknown. References: Bratcher, T. et al. (1979), Finet, Y. et al. (1985), Finet, Y. et al. (1994), Finet, Y. et al.

Finet (2001): The holotype of T. grayi (BMNH: n° 1874.10.29.1) is also the type of T. gracilis Gray; the locality given was “S.E. Africa ?”. Another possible syntype of T. gracilis Gray (BMNH: n° 1874.10.29.2) is also a possible paralectotype of Terebra frigata Hinds, 1844, a Panamic and Galapagan species. Terebra grayi has been cited from the Galapagos in Keen (1971), but according to Bratcher (pers. comm., 1983) and Bratcher Cernohorsky (1987), it is a West African species, not a South African nor a Panamic species. Records from the Galapagos or the eastern Pacific may be based upon confusions or misidentifications. Galapagos Distribution: Unknown. References: Bratcher, T. et al. (1987), Finet, Y. et al.

LACM: AHF 808-38; Finet (2001): In old literature, Terebra guayaquilensis is not recorded as a species from the Galapagos. On the contrary, Terebra elata Hinds, 1844 is mentioned from the Galapagos in Keen (1971), and T. guayaquilensis was considered to be a synonym of T. elata in Keen (1971). Actually, the two forms of T. elata figured by Bratcher Burch in Keen (1971) belong to two species which must be considered separate (Bratcher, 1979). According to Bratcher (pers. comm.), the true Terebra elata does not seem to occur in the Galapagos, and the previous records of “T. elata “ from the archipelago are probably referable to guayaquilensis (Bratcher, pers. comm., 1983). However, and illogically, the Galapagos are not mentioned within the distribution range of Terebra guayaquilensis in Bratcher Cernohorsky (1987). Syn.: Myurella belcheri E.A.

The only other reference to Trivia acutidentata is based on a worn shell from the Galapagos (FMNH 96037) (see Button, 1906; Solem, 1963).

The question was also discussed in Finet (1994); the species was quoted in Finet (1985) as of doubtful occurrence, but erroneously under the name Trivia paucilirata, which actually does not seem to be a synonym of acutidentata, despite Schilder's assumptions.

KAISER (1997 : 48) reports that material in the Los Angeles County Museum (LACM 38-188), previously identified as Glycymeris multicostata, has now been redetermined by L.T. Groves as Glycymeris inaequalis (Sowerby, 1833). Galapagos Distribution: Unknown. References: Bernard, F.R. et al. (1983), Bernard, F.R. et al. (1991), Finet, Y. et al. (2001), Skoglund, C. et al.

Finet (2001): The specimens recorded from the Galapagos may have been misidentified; it is for example certainly the case for a specimen in the CAS collection (CAS n° 40603), which was collected and mentioned in the literature by Angermeyer (1971: 7), and which is in reality a Turbo scitulus (Dall, 1919) (see also Finet, 1985, 1994 1995).

Finet (2001): This species was originally described from an unknown locality (Reeve, Proc. Zool. Soc. Lond., 1843: 186), but later on, Reeve (Conch. Icon., 1848, Turbo, pl. 5 fig. 21) cited the Galapagos Islands as locality for the specimens collected by H. Cuming. Subsequent authors (Carpenter, 1857; Stearns, 1893 1894; Dall, 1909; Tomlin, 1928) also quoted the species from the Galapagos. The locality mentioned by Reeve may be erroneous, and later records may have been based upon misidentifications; there seems to be no actual evidence of the occurrence of this species in the Galapagos (see also Finet, 1994 1995).

Amaea brunneopicta (Dall, 1908) Finet (2001): This species has been mentioned from the Galapagos by Keen (1971); the record was repeated by Finet (1985, 1991). However, DuShane (1974) restricted its southern distribution to Costa Rica, and as no specimen from the Galapagos has been found in the collections, the record of Keen may be considered dubious (see also Skoglund, 1992). The question was also discussed in Finet (1994). Kaiser (1997: 52) includes the species in her list of taxa of rejected occurrence.; Syn.: Eccliseogyra nebulosa Dall, 1919, Epitonium brunneopictum Dall, 1908, fide Appeltans et al.(2010) 2. Callistochiton gabbi Pilsbry, 1893 Finet (2001): Was mentioned from the Galapagos by Bergenhayn (1937). This is considered a spurious record by Smith Ferreira (1977): “No examples of this relatively common Gulf of California Callistochiton were collected in the Galapagos Islands in 1964; nor has it been reported since. In all probability, Bergenhayn’s record (one 7 mm specimen collected at Isla Floreana) is a misidentification for Calloplax duncanus”. 3. Calloplax janeirensis (Gray, 1828) Finet (2001): Was mentioned from the Galapagos by Wimmer (1880). This is considered a spurious record by Smith Ferreira (1977): “This is an Atlantic species, reported by Wimmer from the Galapagos Islands where its occurrence is questionable. We suspect Wimmer’s specimens should be referred now to Calloplax duncanus (Dall, 1919)”. 148 2011 CDF Checklist of Galapagos Marine mollusks 4. Chaetopleura mixta (Dall, 1919) Finet (2001): Specimens from the Galapagos were provisionally referred to this species by Smith Ferreira (1977). Finet (1985, 1991) also repeated this record. But the material was misidentified, and was described as a new species of Calloplax by Ferreira (1982): Calloplax hanselmani, then replaced in the genus Chaetopleura by Kaas Van Belle (1987). 5. Chiton latus Sowerby, 1825 Was mentioned from the Galapagos by Boone (1933). This is considered a spurious record by Smith Ferrera (1977): “Boone reported “one large specimen”, collected at Gardner Bay, Hood Island, Galapagos Islands, by the “Ara”, February 4, 1928. Mr. William E. Old of the American Museum of Natural History, New York, has seen the Boone specimen and reports it (in litt.) to be Chiton stokesii Broderip, 1832, quite probably from Cocos Island, Costa Rica, the erroneous record evidently due to a mixing of labels. This species was not collected on Hood Island (Isla Española) by members of the California Academy’s 1905-1906 Expedition and has not been reported otherwise from the Galapagos Islands. According to Pilsbry (1893, 14: 160-161), Chiton latus Sowerby, 1825, is a synonym of C. magnificus Deshayes, 1827, which he cites only from Valparaiso, Chile. Thus it is evident that this Chilean species is not a constituent of the Galapagos chiton fauna”. This question was also discussed in Finet, 1994. Despite the fact that the species was quoted again from Galápagos by Alamo Valdivieso (1987) in their “Lista sistematica de moluscos marinos del Peru”, Kaiser (1997: 47) maintains it in her list of species of rejected occurrence in Galápagos. 6. Chrysodomus testudinis Dall, 1890 Type locality: near the Galapagos. Finet (2001): The record of this species is rejected by Keen (1971): “From deep water off the Galapagos Islands, in 1485 m. The species has not been illustrated, and the type material was too incomplete for positive placement. DALL even implied that it might prove to belong in the family Turridae. Nomenclaturally, both the generic and the subgeneric names are unacceptable, being synonyms of earlier names, and both pertain to groups that are Arctic or boreal in distribution”. 7. Conus bartschi Hanna Strong, 1949 Finet (2001): Coomans, Moolenbeek Wils (1982) identified a lot from the Galapagos in the Los Angeles County Museum (LACM: 72-227.2) as Conus bartschi. This record was then repeated by Skoglund (1992) and by Finet (1994: 72), but was later discounted by Kaiser (1997: 54), who redetermined the LACM material as juvenile Conus brunneus Wood, 1828 8. Corbula marmorata Hinds, 1843 Finet (2001): According to Coan (2002: 87), the record of this species from the Galápagos Islands by Kaiser (1997: 25) was based on a misidentified specimen of Corbula bicarinata Sowerby, 1833 in the LACM (LACM 34-43). 9. Crepipatella dilatata (Lamarck, 1822) Finet (2001): Was cited from the Galapagos by Dall (1909). Including the Galapagos Archipelago within its range is erroneous and should be discounted, as this species has a much more southern (Peruvian and Magellanic) distribution. 10. Cymatium wiegmanni (Anton, 1839) Finet (2001): Was mentioned from Galapagos by Schwengel (1938) and as a Pleistocene fossil by Hertlein Strong (1939). But, as Beu Kay (1988: 213-214) pointed out, Cymatium wiegmanni of Hertlein Strong, 1939 is not the wiegmanni of Anton, 1839, but rather Cymatium parthenopeum keenae (Beu, 1970). It was also erroneously referred by Hertlein Strong (1955: 134) to costatum (Born), though it is not the costatum of Born, 1778, but rather the costatum of Dall, 1909, which is also parthenopeum keenae (Beu). Before this problem was cleared up, wiegmanni has been listed as a species of doubtful occurrence by Finet (1985). Kaiser (1997: 52) included it in her list of species of rejected occurence. 11. Cypraea rashleighana Melvill, 1888 Finet (2001): Occurrence of this species in Galapagos was only mentioned as a probability (Emerson, pers. comm., 1982). But it has not been confirmed so far, and it is the reason why the species was placed in the list of species with a dubious occurrence in Finet (1985), then omitted in Finet (1994). Kaiser (1997: 52) includes it in her list of species of rejected occurrence. 12. Cypraea schilderorum (Iredale, 1939) 149 2011 CDF Checklist of Galapagos Marine mollusks Finet (2001): Occurrence of this species in Galapagos was only mentioned as a probability (Emerson, pers. comm., 1982). But it has not been confirmed so far, and it is the reason why the species was placed in the list of species with a dubious occurrence in Finet (1985), then omitted in Finet (1994b). Kaiser (1997: 52) includes it in her list of species of rejected occurrence. 13. Cystiscus politulus (Dall, 1919) Syn.: Marginella regularis Carpenter (auct., non Carpenter, 1864). Finet (2001): A specimen from the Galapagos was tentatively identified by Hertz (1976) as Cystiscus politulus (Dall); “Marginella (Cystiscus) regularis Carpenter” was also mentioned from the Galapagos by Hertlein Strong (1955). But, according to Roth Coan (1971), both Marginella regularis Carpenter (auct.) and the true Marginella regularis Carpenter, 1864 have to be excluded from the Galapagan fauna: “As shown by Coan Roth (1966), Marginella regularis Carpenter, 1864, is a synonym of Granula subtrigona (Carpenter, 1864), a species not present in any Galapagos material we have examined. The name Marginella regularis has also been applied to Cystiscus politulus (Dall, 1919), another species which apparently does not occur in the Galapagos Islands”. The question was also discussed in Finet (1994). Material from Galapagos in the Los Angeles County Museum of Natural History (LACM: 72-196) was also identified as Cystiscus politulus by G. Coovert (fide Kaiser, 1997: 54), but it is more likely Granula insularum Roth Coan, 1971 (McLean, pers. comm., in Kaiser, 1997: 54). 14. Fissurella microtrema Sowerby, 1835 Finet (2001): Syn.: Fissurella rugosa Sowerby, 1835 (type locality: Galapagos); ANSP: 50276, BMNH: 1966397 (Syntypes of Fissurella rugosa Sowerby, 1835). Mc Lean in Keen (1971) considered that the true F. rugosa Sowerby is not a Galapagan nor a Panamic species: “Stated to have come from the Galapagos Islands. No specimen matching the original illustration and description has been collected there since. The species may well be from the Caribbean and a synonym of F. rosea (Gmelin, 1791). The F. rugosa of authors is here considered to be F. microtrema”. Having studied material from the SDNHM and the LACM, Hertz (1983) concluded that Fissurella microtrema and Fissurella rugosa may be separate valid species. But after having examined additional material in the ANSP and the LACM, as well as the type specimens of Sowerby for both species, Finet (1994) thinks that F. microtrema and F. rugosa may be synonyms, showing many intermediate forms, similar to but probably distinct from the common Caribbean Fissurella rosea (Gmelin, 1791), of which the type material was not examined however. The syntypes of F. rugosa Sowerby are recorded from the Galapagos Islands, but it may be in error (see also Hertz, 1983); only another lot of worn specimens identified as F. microtrema (ANSP 50276) is recorded from the Galapagos, but its origin (“Galapagos Isl., Dr. R.E. Griffith”) might be doubtful as the locality of anything this old in the collection of the ANSP is questionable (see Finet, 1985). Also Fissurella rugosa of authors is often quoted from the Galapagos (see all the authors mentioned above). But no other specimen of F. rugosa or microtrema whatsoever has been collected in the Archipelago ever since then. As it is a quite common species elsewhere in the Panamic Province, its occurrence in the Galapagos as a permanent component of the littoral fauna remains doubtful. The question was also discussed in Finet (1985), and FINET (1994). 15. Fissurella mutabilis Sowerby, 1835 Finet (2001): Was cited from the Galapagos by Carpenter (1857) and Stearns (1893). As it is a South African species, these records should be discounted (see also FINET, 1994). 16. Fissurella nigra Lesson, 1831 Finet (2001): Was cited from the Galapagos by Dall (1909). Including the Galapagos Archipelago within the range of this species should be discounted as it has a much more southern (Peruvian and Magellanic) distribution (see also Finet, 1994). 17. Flabellina iodinea (Cooper, 1863) Finet (2001): Identification of the relevant material should be deleted and provisionally considered as Flabellina sp. (pers. comm. of T.M. Gosliner, 1994, in Kaiser, 1997: 55). 18. Granula subtrigona (Carpenter, 1864) Syn.: Marginella regularis Carpenter, 1864. Finet (2001): This species is not to be confounded with “Marginella regularis Carpenter”, auct., a name which has been cited from the Galapagos by Hertlein Strong (1955), and which has been applied to Cystiscus politulus (Dall, 1919). According to Roth Coan (1971), both Granula subtrigona (Carpenter) and Cystiscus politulus (Dall) are not occurring in the Galapagos. 150 2011 CDF Checklist of Galapagos Marine mollusks 19. Hyotissa hyotis (Linnaeus, 1758) Finet (2001): Hyotissa hyotis is an Indo-Pacific species, but the Panamic Hyotissa solida (Sowerby, 1871) has sometimes been confounded by some authors with Hyotissa hyotis, or even thought to be a form or a synonym of it, hyotis being then also quoted from Galapagos. However, Bernard et al. (1991) considered the two taxa as separate species, and have excluded Hyotissa hyotis from the Galapagos fauna. 20. Leptochiton alveolus (Lovén, 1846) Finet (2001): FERREIRA (1979) considered the species Leptochiton alveolus (Lovén, 1846) as a synonym of Leptochiton opacus (Dall, 1908), alias Leptochiton belknapi Dall, 1878, but alveolus is now regarded as a separate Atlantic species (Kaas Van Belle, 1987; Kaiser, 1997: 47). Since L. opacus (Dall) has been erroneously quoted from the Galápagos (see that species hereby), it may have been thought that L. alveolus could also extend its distribution range to the Galápagos archipelago. But actually, neither Leptochiton opacus (= L. belknapi), nor of course L. alveolus (extralimital, Atlantic) pertain to the chiton fauna of the Galápagos (see Kaiser, 1997: 47). 21. Leptochiton belknapi Dall, 1878 Syn.: Lepidopleurus opacus Dall, 1908, L. mesogonus Dall, 1902, L. halistreptus Dall, 1902, L. luridus Dall, 1902, L. farallonis Dall, 1902, L. benthus Haddon, 1886; USNM: 110664 887578 (Lectotype and Paralectotype of Lepidopleurus opacus Dall, 1908) (between the Galápagos and the Peruvian coast, in 2005 fms = type locality), SBMNH: 34460 (Paralectotype of L. opacus Dall) (same locality); Finet (2001): The species Leptochiton opacus (Dall, 1908), a synonym of L. belknapi Dall, 1878 (Kaas Van Belle, 1987), was dredged by the USS Albatross of the United States Fish Commission between the Galápagos Islands and the Peruvian coast in 2005 fathoms" (3670 m) (USFC Sta 4647: Lat. 4°33’ S and Long. 87°42’ W) 22. Limaria hemphilli (Hertlein Strong, 1946) Syn.: part. Lima hians auct., non Gmelin, 1791; Finet (2001): It is possible that Dall (1908) referred to this taxon when he cited “Lima (Mantellum) hians Gmelin” from the Galapagos, and not to the true Lima hians of Gmelin, 1791, which is an European species; but this record should be discounted anyway, as L. hemphilli has a more northern distribution along the Californian and Mexican coasts. 23. Littorina coccinea (Gmelin, 1791) Finet (2001): According to Reid Kaiser (2001: 385), the “lot of 16 specimens from Wreck Bay, Chatham Island, Galápagos Islands (leg. R.W. Smith, 1931, G. Vanderbilt collection, ANSP 170347) is considered unreliable. This is because the sample is remarkably large for a rare immigrant species. Furthermore, the following lot in the ANSP registration sequence is a shell of another Indo-West-Pacific species, Littoraria intermedia, said to be from the same locality (...). This coincidence is likely the result of mislabelling”. 24. Lottia mitella (Menke, 1847) Finet (2001): Originally described from Mazatlan, Mexico, this species has been cited from the Galapagos in the literature by several authors. These citations were partly based upon misidentifications of specimens of Lottia smithi Lindberg Mc Lean, 1981 or Lottia mimica Lindberg Mc Lean, 1981, from the Galapagos Islands (Villamil, Isabela Island, leg. C.R. de Sola, 1928: AMNH 87165; north of Tagus Cove, Black Bight, Isabela Island: CAS 93774 [ex 9970, loc. n° 27221], see Hertlein Strong, 1955: 140, pl. A, figs 2,3). The quotations from the Galapagos were also sometimes replications from one author to another. The question was also discussed in Finet (1994). 25. Macoma" plebeia (Hanley, 1844) auctt." Finet (2001): Mentioned by Cauquoin (1968) as having been collected from the Galapagos by Mr. Hoffstetter. The type locality assigned to the species was “Real Lejos” (Nicaragua) (Pilsbry Lowe, 1932: 95), probably in error, as the type in the British Museum is now labelled from West Africa (see Keen, 1971: 900). Both Keen (1971) and Bernard (1983) recognize the species as extralimital, being probably a synonym of Psammotreta cumana (da Costa, 1829), from Senegal. 26. Nerita fulgurans Gmelin, 1791 Finet (2001): A Caribbean species erroneously cited from the Galapagos by Schwengel (1938). 27. Neritina latissima Broderip, 1833 151 2011 CDF Checklist of Galapagos Marine mollusks Finet (2001): Neritina cassiculum Sowerby, 1836, a synonym, has been mentioned by Wellington (unpublished, 1975). One lot of Neritina latissima (LACM 59991 - leg. W. Luke, ex Tremper) is also recorded from Islas Galápagos"; but this lot 28. Pecten magnificus (Sowerby I, 1835) Acc. name: Nodipecten magnificus Sowerby I, 1835 29. Persicula frumentum (Sowerby, 1832) Finet (2001): Despite the records from the Galapagos Islands by Dall (1871: as P. catenata 30. Petricola amygdalina Sowerby, 1834 Finet (2001): Originally described from the Galapagos by Sowerby (1834), but type material is missing. Its occurrence in the Galapagos has been reported by several authors like Müller (1836), Carpenter (1857), Stearns (1893), Pilsbry Vanatta (1902), Soot-Ryen (1932), and even repeated very recently by Bernard (1983), Finet (1985: as of doubtful occurrence), Skoglund (1991), or Finet (1994). But as it is not supported by any collection material, and as P. amygdalina is a nomen dubium, records can be discounted (Coan, in litt., 1995 1996). Bernard et al. (1991: 33) and Kaiser (1997: 49) also rejected the records from Galápagos. 31. Phos articulatus Hinds, 1844 Finet (2001): Juvenile specimens from the Galapagos are in the LACM collections (LACM nrs. 66-211, AHF-431, AHF-451, AHF 190-34). They may be misidentified and pertain to the species Phos laevigatus (A. Adams, 1851) (see also Finet, 1985 1994). 32. Semele corrugata (Sowerby, 1833) Finet (2001): Was mentioned erroneously from the Galapagos by Hertlein Strong (1955) on the basis of misidentified material, as pointed out by Coan (1988; 1989): “record of ... Semele corrugata (Sowerby, 1833) from Isla Baltra was based on a [beachworn] specimen of Semele flavescens (Gould, 1851) (CAS 064672), [a species] which had not previously been reported from the Galapagos”. 33. Semele decisa (Conrad, 1837) Finet (2001): Eventual records of this species from the Galapagos must be rejected, according to Coan (1989): “The Californian species Semele decisa (Conrad, 1837) was reported from the Galapagos, but what people were actually finding is the similar Semele sowerbyi Tryon, 1869”. 34. Semele solida (Gray, 1828) Finet (2001): Was mentioned erroneously from the Galapagos by Pilsbry Vanatta (1902) and by Soot-Ryen (1932), probably on the basis of misidentified material, as pointed out by Coan (1988; 1989): “record of Semele solida (Gray, 1828) from Isla Isabela ... was based on a [beachworn] specimen of Semele flavescens (Gould, 1851) (CAS 064527), [a species] which had not previously been reported from the Galapagos”. 35. Tectura fascicularis (Menke, 1851) Finet (2001): “Acmaea fascicularis Menke” has been mentioned from the Galapagos only by Schwengel (1938); this record is probably erroneous and was possibly based upon misidentified specimens from Wreck Bay, Chatham Island, collected by the Geo. Vanderbilt expedition (R.W. Smith, 1937) (ANSP 170308), and now reidentified as Lottia rothi (Lindberg McLean, 1981). The question was also discussed in Finet (1994) and Kaiser (1997). 36. Trivia occidentalis (Schilder, 1922) Syn.: Trivia pulla (Reeve, 1846, ex Gaskoin, MS) (non Gmelin, 1791); Finet (2001): Although Trivia pulla has been mentioned from the Galapagos by the numerous authors, Keen (1971: 903) considered that it must be rejected from the eastern Pacific fauna: “This was described without locality but has been considered to be West American by some authors. Schilder in 1922 renamed the homonym T. occidentalis, accepting a Pacific provenance. Later (1932), he synonymized it with a Caribbean species, T. antillarum (Schilder, 1922). Presumably, therefore, it is not a Panamic form.” The question was also discussed in Finet (1994). Later, Kaiser (1997: 52) included occidentalis in her list of species of rejected occurence. 37. Xanthochorus xanthostoma (Broderip, 1833) Finet (2001): Originally described from Valparaiso, Chile, it has been reported from the Galapagos as “Trophon ? xanthostoma, Brod.” by Stearns (1893). This record seems erroneous, as the species has a 152 2011 CDF Checklist of Galapagos Marine mollusks more southern (Peruvian) distribution. References: 1. Abbott, R.T. (1974) American Seashells.
