Ianthina fragilis Lam. Florida Keys; Key West. Has been 

 picked up on Egmont Key by Mr. Charles Moore. 



Ianthina globosa Swain. Key West. On a certain Sunday morn- 

 ing, while at Key West, I found the beach strewed with millions of 

 Ianthina fragilis and globosa, the former being most abundant. 

 Thousands of these shells contained the animals in a perfectly fresh 

 state, and were no doubt living when thrown up the night before. 

 There had been no storm, nor even a change of wind, and though I 

 had searched the same beach the evening before, I had not found an 

 example of either species. It seems as if a vast school of these animals, 

 carried by some current, had been landed bodily on the rocky beach. 



Cixcum sp. ind. Tortugas. 



Cozcum pulchellum Stimp. Tortugas. 



Ccecum floridanum Stimp.? Anna Maria Key. 



Eulima conoidea Kurtz and Stimp. Dredged in Tampa Bay. 



* Eulima psila Wat. Obtained of Mr. Isaiah Greegor, and said to 

 come from the east coast of Florida. 



Niso aeglees Bush. Tampa Bay; dredged. 



Turbonilla i liter rupta Tott. Tampa Bay; dredged. 



Turbonilla areolata Verrill? Tampa Bay. 



Turbonilla gracilis Dek. Tampa Bay. 



Odostomia granatina Dall. Dredged in Tampa Bay. 



Odostomia impressa Say. Cedar Keys; J. B. Upson, Tampa Bay. 



Oscilla nivea Morch. Tortugas. 



Pyramidella dolobrata Lam. Little Sarasota Pass. A single fresh 

 shell was found at the above locality. I found it abundantly fossil in 

 the hammocks south of Manatee, in company with Bulla striata, the 

 latter now found only rarely living on the Florida Keys. With these 

 fossils were associated a great majority of the species living to-day on 

 the adjoining coast. I believe that Pyramidella dolobrata has not be- 

 fore been reported from Florida, though it is abundant in the Antilles. 



Obeliscus crenulatus Holmes. Dredged in Tampa Bay. 



Obcliscus Candidas Morch. Dredged with the typical tessellatus.
