Station. Under stones and in sandy places ; Sowerby. 



On the rocks ; Kiener. 



We found fine perfect specimens alive under stones near 

 low water mark. Kiener's statement, that they live on the 

 rocks, is probably erroneous. Like Cyprreas, they seek con- 

 cealment.

"We found 1 young, and 3 mature shells on the reef at Pa- 

 nama. Although we turned over many hundred stones in the 

 search, no more could be found. 



Our specimens exhibit the pliciform columellar teeth, and 

 the pustulous enamel of the surface in full development. M.
