Additions to a catalogue of the described Recent and Tertiary species of Acesta and Plicacesta
AbstractIn an earlier number of the Tulane Studies in Geology (vol. 1, no. 2, 1963), the writer presented a catalogue of the described Recent and Tertiary species of Acesta, based upon references collected while preparing the description of Lima (Acesta) bullisi H. E. Vokes. At that time it was noted that since the catalogue was the result of a canvass of the literature it was "quite possible" that some species had been overlooked. This latter statement subsequently has proved to be correct and it is now possible to supplement the previous listing and thus to make it more complete. The writer is greatly indebted to Professor R. L. Merklin of the Paleontological Institute, Akademy Nauk, U.S.S.R., for calling his attention to the eastern Siberian occurrences of Acesta and furnishing a photocopy of an important reference.
