PwyjipZZus icZ., Remond, Pal. Chile, p. 30. Cret.; Patagonia.? 



I place this species in the list because Remond attributes it to Port Famine. At the same 

 time I doubt the propriety, suspecting that a confusion has arisen from tiie fact that it was 

 refigured by d'Orbigny in the report of the voyage of the Astrolabe and Zelee in a mixture of 

 South American and Bast Indian species.

Not a true Hippochrenes of the type of H. macroptera, but nearer to that than to any named 

 genus. The expanded lip suddenly narrows in the middle to a narrow tongue. But it will sub- 

 serve no good end to give generic names to each shape of Up in the protean group of alate shells, 

 as I have already pointed out in my notes on the genus Anchura. If species of this type were 

 numerous it would aid classification to give them a distinctive name; but where but a single 

 species is known it results rather in confusion than simplification, to multiply names.
