Hab. Guacomayo, Amer. Merid. H. Cuming legit. 



The only specimen we have seen is in Mr. Cuming's collection ; 

 it bears a very near resemblance to the common West Indian spe- 

 cies named Sc. muricata by Kiener, from \vhich it differs in having 

 the angle of the varices elevated into a tooth or point. It is also a 

 thinner shell, \vith the laminated varices narro\ver. Found in sandy 

 mud at a depth of eleven fathoms.
