Southern part of Florida and islands and keys adjacent to' the 

 coast, probably introduced from Cuba. 



This species inhabits trees, upon the branches of which it is 

 found. In winter it hibernates by attaching its aperture very 

 strongly to the bark of the tree, by means of a thick, viscid, 

 opaque secretion, which hardens to the consistency of glue. In 

 tearing it away, the bark or the shell is fractured sooner than the 

 secretion. At other times, when the animal withdraws into the 

 shell, it secretes only a thin, transparent epiphragm. 



Jaw (Terr. Moll. I, pi. v, f. 4a, b) slightly arched, ends pointed; 



composed of numerous plates. 



The lingual membrane has 94 

 rows of 55 — 1 — 55 teeth each, 

 arranged diagonally across the 

 membrane ; teeth similar, stout, 

 blunt, broader above than below, 

 apex recurved.
