Pfeiffer 's description of scyphus indicates a far larger shell 

 with more whorls than the specimens commonly known under 

 that name in collections, judging by those received from 

 Morelet, Jetschin, Conemenos and others. As no specimens 

 agreeing with Pfeiffer 's account are accessible and the in- 

 ternal structure is unknown, its relations to other forms of 

 the region, including those here denned as subspecies, cannot 

 be denned. The figures of Kuester, reproduced in our pi. 3, 

 fig. 1, do not agree entirely with the original description, 

 being smaller and showing two columellar lamellse. 



Whether any of the later references and localities pertain 

 to the real scyphus cannot be affirmed at this time. The dis- 

 tribution of scyphus is therefore uncertain, and the records 

 following undoubtedly were based upon several quite distinct 

 forms. 



Reinhardt, followed by Westerlund, regards P. scyphus as 

 specifically distinct from doliolum. Boettger treated it as a 

 variety of the latter. He has given the following localities 

 for scyphus, but only an inspection of his collection would 

 show what forms he included under this name: European 

 side of the Dardanelles (v. Maltzan), Brussa (Andreae) and
