Summary, References cited., Explanation of plates [Excerpt from Intro] The following observations on the trematode genera Helicometra, Helicometrina, and a new related form are based on material collected at the Carnegie Biological Laboratory at Tortugas, Florida. This material is apart of extensive collections made there during the summers of 1930, 1931, and 1932. I am indebted to Dr. W. H. Longley for identification of the host fishes. Most of the study of specimens was made in the ZoologicalLaboratory, University of Nebraska. Helicometra Odhner, 1902, and Helicometrina Linton, 1910, are relatedgenera of marine fish trematodes of the family Allocreadiidse, sub-family Allocreadiidae. Both genera possess eggs with long, unipolar filaments. Seller Inventory # 20150908001
