Each dart is accompanied by certain movements of the foot that are very misleading when considered by themselves. Not infrequently 2) it has been supposed that the swimming is accomplished by the energetic spreading of the muscular flaps accom- panied by th

On viewing this region from above the papillae appear bunched together or spread apart, the result of the sudden dilatation or partial contraction of the opening. The sides of the siphonal opening are in constant motion in and out, though this motion is alternate and rhythmic. The proboscidif

The shell as before re- marked differed in no respect from that of S. velum, and I am puzzled at the remarkable difference in structure of the siphonal opening. The question arises whether the Annisquam form may not be the young of 5. borealis. This can only be decided by securing a living specimen of this rare form. P

Under a higher power these bodies have the appearance of setigerous follicles. Stempell figures one in his memoir of 5. togata as a simple alveolar border gland. His figure shows a much more bulbous gland and the thread-like extension is not shown as in those here figured (Fig. 5)

RMRG31MT–. The Cambridge natural history. Zoology. i66 THE GILL IN PELECYPODA CHAP. 1. The simplest form of gill (^Nucula^ Leda^ Solenomya^ etc.) is that which consists (Fig. 76, A, compare Fig. 100, p. 201) of two rows of very short, broad, not reflected filaments, the rows being placed in such a way that they incline at right angles to one another from a common longitudinal axis. The filaments are not connected with one another, nor are the two leaves of each gill united at any point. (^Protobranchiata.^ 2. In the Anomiidae^ Arcadae, Trigoniidae^ and Mytilidae each gill consists of two plates or rows

It is surprising, however, to see how closely they resemble one another (Fig. 20). At first sight S. borealis seemed to be an enlarged S. velum. The color of the foot and ventral membrane varies.

The gills are most peculiar in Solenomya. As Pelseneer has shown, there is only one gill on each side having an upward and downward series from a central base. This line dividing the upper and lower series runs from the dorsal anterior portion of the gills to nearly a ventral point posteriorly (Fig. 12). The filaments are distinctly separate and are beautiful in their regularity. The filaments are arranged o
