Atlantic and Gulf States from North Carolina to Texas, thus inhabit- 

 ing all the Southern Region.* Very common on the islands and keys 

 along the coast. 



Animal: see above, p. 345. 



The habits of this animal are somewhat aquatic. It is found on the 

 sea-islands of Georgia and around the keys and everglades of Florida, 

 and in these situations the shell often attains the length of 4 inches ; 

 when found on the oyster hummocks and less humid localities it sel- 

 dom exceeds 1 inch in length. Mr. Say found it in the marshes im- 

 mediately behind the sand-hills of the coast. It is most readily found 

 in the center of the clumps of coarse grass on these marshes. In young 

 individuals the spire forms but a small proportion of the shell, but in 

 the old it often forms one-third of the length. 



The animal is in part, if not altogether, carnivorous, and its power- 

 ful lingual membrane, armed with long, sharp-pointed teeth, is well 

 adapted to its food. By its action the soft parts of its prey are rapidly 

 rasped away or are forced in large morsels down the cesophagus. The 

 animal has been seen to swallow entire the half-putrid remains of a 

 Helix, and to attack Limaces confined in the same box with it, rasping 

 off large portions of the integument, and in some instances destroying 

 them. In one instance an individual attacked and devoured one of its 

 own species, thrusting its long neck into the interior of the shell and 

 removing all the viscera. I found many specimens of Polygyra vol- 

 voxis in the stomach of individuals collected by me at Saint Augus- 

 tine, Fla. 



The testicle is an oval mass, separated from the liver, as in the Li- 

 maces. The epididymis appears from a hilum in the side of the testicle ; 

 at first but slightly tortuous, it becomes convoluted just before end- 

 ing. Its accessory gland is large. The penis sac is long, large, and cla- 

 vate, very gradually enlarging from the base to the summit. The vas 

 deferens, which joins the latter point, is long, moderately tortuous, and 

 wide. The retractor muscle is inserted into it near its termination in 

 the penis sac. The bladder is oval, constricted ; its duct is as long as 



*Mr. T. R. Aldrich writes me that it is found as far north as Macon, Ga., Bibb 

 County, Alabama, and Jackson, Miss.
