Murex cellulosa Con.? Dredged in Tampa Bay. Agrees better with 

 Conrad's description of this species than with anything else. 



Muricidea hemphilli Dall. Long Key to Sannibel Island. Quite 

 variable in sculpture and coloring. I have a bright orange-colored shell. 



Muricidea ftoridana Con. Abundant at Tampa Bay and vicinity. 



Urosalpinx cinereus Say. Occasionally found in the vicinity of 

 Tampa Bay. 



Urosalpinx cinereus Say, var. A couple of heavy-shouldered shells, 

 with short spire, somewhat worn, were picked up on Sannibel Island. 

 Mr. Dall supposes them to be a variety of this species. 



Urosalpinx tampaensis Con. Occasionally found in Tampa Bay. 



Eupleura caudata Say. Dredged in Tampa Bay. 



Eupleura muriciformis Brod. Anna Maria Key. A heavy, white 

 shell, very different from E. caudata as dredged by me; but Mr. Dall 

 believes it to be the same. 



Purpura hozmastoma L. Key West. 



Purpura florida?ia Con. Florida Keys; east coast, Mr. T. L. Cun- 

 ningham. 



Purpura undata Lam. Florida Keys. Both this and the preceding 

 are, no doubt, forms of the widely distributed and variable Purpura 

 hcemastoma. 



Purpura deltoidea Lam. Florida Keys. 



Ricinula nodulosa C. B. Ad. Key West; Tortugas. Abundant. 



Rhizocheilus ( Coralliophila) galea Chem. Tortugas, one worn shell. 

 Two worn shells were found in Tampa Bay, which are probably this, 

 but are more 'slender and not so solid as the Tortugas specimen. 



Triton tritonis L., var. nobilis Con. I found about thirty living 

 specimens on the reefs at Tortugas, of an apparently stunted form, 

 being very solid and having a heavy lip, though not over seven or 

 eight inches in length. Capt. William Bahrt, of Braidentown, has a 

 noble shell from Duck Key that measures fourteen inches in length. 



Triton pilearis L, Tortugas. This is Calkins' T. Tcliei. 



Triton chlorostomus Lam. Tortugas. One fairly good adult shell. 



Triton femorale L. Four fine living shells were obtained at Key 

 West; they are not so large or bright as shells from the West Indies. 



Triton tuberosus Lam. One shell found at Tortugas. 



Triton lamellosus Dkr. Key West. 



Triton lanceolatus Mke. Anna Maria Key, one fine shell ; worn 

 shells were picked up at Key West. 



Triton eximius Reeve. Key West; Tortugas. 



Triton araehnoides Morch. Tortugas; several worn and broken ex- 

 amples. 



Fasciolaria tulipa L. Common and variable. A form found in shel- 

 tered bays is much duller colored and coarser than those of the open 

 sea. A mahogany-colored form is occasionally found on the Keys.
