SIMPSON CONTRIBUTIONS TO THE MOLLUSCA OF FLORIDA. 6 I 



and L. peloritana Cantr. I have shells with the latter name said to be 

 from the Mediterranean. 



Tr if or is decoratus C. B.«Ad. Tortugas; Tampa Bay. 



Triforis nigrecinctus C. B. Ad. Tortugas; Tampa Bay. 



Triforis turris-thomae Chem. Tortugas. 



Triforis intermedins C. B. Ad. Tortugas. 



Triforis ornatus Desh. Tortugas. 



Triforis vane go tits A. Ad. Tortugas. 



*Goniobasis papulosa Anth. Holmes' Creek, West Florida. Mrs. 

 George Andrews. Dead shells of this species were received from Mr. 

 S. L. Cunningham, from Sumpter County. 



Skenea sulcata Bush. Tortugas; very large. 



Rissoina pulchra C. B. Ad. Tortugas. 



Rissoina striosa C. B. Ad. Tortugas. 



Rissoina cancellata Phil. Tortugas. 



Rissoina reticulata Sby. West coast; probably Tampa Bay. The 

 label containing locality of this species* was lost. 



Bythinella monroensis Frau. Ware's Creek; Pine Level. 



Bythinia tcntaculata Drap. Key West. These shells were found 

 near a salt pond, dead, and slightly weathered, and may have been 

 brought in ballast. I submitted them to Mr. Ancey, who identified 

 them as above. I have the same shell, taken alive, from New York, 

 where it has been introduced from Furope. 



Hydrobia wetherbyi Dall. Pine Level, Manatee County.

with Bythinia tcntaculata at the above locality, and were identified, 

 with doubt, by Mr. Ancey. 



*Campelomafloridense Call. Orange County. T. L. Cunningham. 



*Campeloma lima Anth. ? A shell was obtained from Mr. R. C. Stuart, 

 marked Florida, which seems to agree well with Dall's figure and de- 

 scription of the above species, only that it is lighter in color. 



*Ampullaria depressa Say. Sumpter and Volusia Counties, Cunning- 

 ham; Orange County, Pilsbry. 



Ampullaria caliginosa Reeve. Manatee County near Braiden Creek, 

 one worn shell; Royal Palm Hammock, several hundred shells; Miami 

 region; Cedar Keys. These agree in most respects with Dall's de- 

 scription in Hemphill's Shells. I have shells of A. depressa which are 

 malleated, and have as large an umbilicus as A. caliginosa. Some 

 shells of the latter species have a brownish operculum, and are not
