Neritina Virginea, L. 



W. Indies, Brazil. 



Phasianella Kochi, Phil. 



South Africa. . 



This species is not unlikely but a variety of Phasianella 

 pulla, L., from the Mediterranean, the west coast of Africa, etc. 



Turbo pica, L. 



W. Indies, Nicaragua, Panama. 



This large and beautiful shell is abundant along the south- 

 ern shores, where it also occurs imbedded as a sub-fossil in the 

 calcareous rock. It appears to be always largely water-worn, 

 and in no instance did it contain the animal. Indeed, I am 

 assured by old residents who have intentionally sought for the 

 animal that it has never been found in the island-waters. 

 Probably the animal inhabits the deeper waters, and only the 

 empty shell is cast upon the beach.
