tinctive characters; from intertexta (uobis), -which it somewhat re- 

 sembles, it ma5' be distinguished by its less acute form, less ^. ,„. 

 uumerous whorls, and by its want of reticulated surface so 

 peculiar to that species. Bears some resemblance to M. hella, 

 Con., but differs in form of outline and aperture, and has no 

 beaded line; is also more elevated than J/, hella. — Antlwny. 



This species differs from symmetrica in being more cylin- 

 drical, with the wliorls more flattened.

 Melania, sp. 415. 



Description. — Shell ovate, smooth, moderately thick; spire very 

 short, consisting of 4-5 nearly flat whorls, with a broad, dark brown 

 Pj ^gg band revolving in the centre of each; body- whorl large, 

 with one band above the middle, and another at base, sub- 

 angulated ; sutures irregularly impressed, distinct ; colu- 

 mella well rounded, indented and reflected at the middle so 

 as partially to conceal a small, umbilical opening; aperture large, 

 broad, ovate, within banded. 

 Habitat. —Alabama. 



Diameter, -30 (Jh millim.); length, -44 of an inch (11 millim.). 

 Length of aperture, -25 (G millim.); breadth of aperture, -17 of an 



inch (4 millim.). 



Observations. — A short shell almost like an ancvlosa ; a single speci- 

 men only is before me, but is too remarkable to be confounded with 

 any known species. The uncommonly broad, dark band, surrounded 

 by the generally yellow epidermis, gives it a lively appearance. — 

 Anthoni/.
