equal diversity of coloring. There were some smooth shells, others 

 wiih rib-like striae, as well as great variation in the height of spire and 

 the carination of the outer whorl. In fact, it seemed as though all the 

 forms I had hitherto met with of this protean species, were here mixed 

 together, as if to prove at a glance that they were merely forms of one 

 and the same thing. 



Helix ( Paly gyra) febigeri Bid. Sumpter County, Cunningham; 

 K^v West. I cannot in any way distinguish these from shells with the 

 same name from New Orleans. Those received from Mr. Cunningham 

 were labelled Polxgyra febigeri. Undoubtedly a form of H. cereolus. 



Helix ( Polxgyra) pustula Fer. Shaw's Point, at the mouth of the 

 Manatee River; Cedar Hammock, and occasionally other localities in 

 Manatee County; Gainesville, J. B. Upson. 



* Helix (Polygyra) pustuloides Bid. Cedar Keys, J. B. Upson. 



'■'Helix (Polygyra) avara Say. Sumpter County, Cunningham; 

 Jacksonville, Hemphill. 



* Helix ( Triodopsis) hopetonensis Shutt. Jacksonville, J. B. Upson; 

 Cedar Keys, Hemphill. 



Helix (Mesodon) major. A single fine shell of this species was seen 

 in the possession of Mr. R. C. Stuart, who collected it while on a cruise 

 along the West coast. 



Helix (Mesodon) jejuna Say. Point Pinellas on shell mound, abun- 

 dant but dead ; Terraciea Island ; banks of Ware's Creek ; Braidentown ; 

 and Fogartyville. The only mollusk ever found in high dry pine woods 

 in Florida. I have seen it crawling on barren dry sand near Braiden- 

 town, and around my dwelling, and along the road in Fogartyville. 



Helix (Mesodon) mobiliana Binn. This form of jejuna was found, 

 associated with the typical shell. 



Helix (Strobi/a) hubbardi Brown. Cedar Hammock, Manatee 

 County; small and very light colored. A larger dark brown shell was 

 found at Goodland Point, and Evans' plantation. 



Helix [Strobila) labyrinthica Say. Cedar Hammock; hammock 

 south of Manatee River, rather plentiful. Fossil also at the latter 

 locality. 



Helix (Heniitroehiis) varians Menke. Key West. 



Helicodiscus lineata Say. Terraciea Island ; Pine Level, in a swamp 

 in moss about the roots of trees. 



Bulimulus multilineatus Say. Key West; dead shells, but many of 

 them large and in good condition. At Pine Key (Lower Keys) about 

 one hundred and twenty fine large specimens were collected from trees 

 and shrubs, at a few feet of elevation from the ground. All were at- 

 tached (they were collected in May) by a thick epiphragm. Torch 

 Kev. a few dead shells. Mr. John Brown, of the U. S. Coast Survey 

 Schooner "Quick," brought me about sixty living specimens from Cax- 

 onibas. of what seems to be a smaller, darker variety than those I 

 collected.
