170 THE BERMUDA ISLANDS. 



Dall, in his list of the West Atlantic marine Mollusca (Bull. 

 U. S. National Museum, No. 24, 1885), includes Oliva mutica, 

 Say, among his Bermudian species, and quotes Krebs as his 

 authority. This is an error. Krebs makes no mention of the 

 occurrence of the species in the Bermudas (Catalogue West 

 Indian Marine Shells, p. 39). 



Columbella mercatoria, L. 



W. Indies. 



Columbella cribraria, Lam. 



Florida, Bahamas. 



Columbella (Anachis) sp. ? 



A form closely allied to A. plicaria, from New Caledonia. 



Cythara (Pleurotoma), n. sp. 



Identical with a form from Key Largo, Florida. 



Conus Agassizii, Dall. 

 Strombus gigas, L. 



Florida, W. Indies, S. America. 



Strombus accipitrinus, Mart. 



W. Indies. 



All the specimens of this species that I have seen from the 

 Bermudas lack the epidermis, and have the columellar sur- 

 face of a leaden, gray color. They seem to differ from 

 the normal type of the species in having a broader and more 

 elevated spire, and in a more regular nodulation of the body- 

 whorl. 



Cypraea cervus, L. 



W. Indies, Panama. 



This species grows to a very large size. A specimen which 

 I had the privilege of examining in the collection of Mr. Bar- 

 tram, of Stock's Point, far surpasses in this respect all other 

 specimens of the species which have come to my notice. The 

 species occurs as a sub-fossil at St. George's and elsewhere.
