A small, subglobose, smooth shell, sufficiently described and figured in the above-quoted works. All the 
Specimens which I have seen, even the typical one in Dunker’s collection, now in the Berlin Museum, 
are of a dull white, probably bleached. 
Hab. Cuyrran Mexico: Zimapan, State of Hidalgo (David 1%), 
Some Cuban specimens, given, with the name S. brevis, Dunk., by Gundlach to the 
Berlin Museum, approach this species closely in form, but are considerably smaller and 
thinner. I am not quite satisfied concerning their identity as species.
