Pilsbry (1907) emphasizes that his specimen differs from m talismani in size and in the shape of the latus infra - medium, the plate in Gruyel's specimen being slightly smaller as .pared with the height of the adjoining rostral and carinal latera. Pilsbry evidently did not pay sufficient attention to the difference in size of the two specimens. It is impossible to trace dif- ferences of taxonomic value in the drawings and descriptions given by Gruvel (1902) and Pilsbry (1907).-Pilsbry also mentions some detached valves of a much larger, macerated specimen from another locality, the identity of which, however, is questionable: onlv in exceptional cases is it possible to identify a recent Scalpel- lum on the basis of some detached plates. Pilsbry' mentions and figures a rudimentary rostrum which, in intact specimens, is completely covered by the upper parts of the ros
