Description, — ^^Shell subglobular with two or three volutions, 

 the length of a crushed individual being 34 mm., and its width, 

 somewhat increased by crushing, 28.5 mm. Aperture very broad, 

 broadly rounded in front and narrowly rounded posteriorly. Sur- 

 face marked only by lines of growth. 



Remarks. — -A single crushed and distorted cast of this species 

 has been met with in the recent collections of the Survey. This 

 specimen has been compared, not only with the type of the species, 

 but alsoi with other examples from southern localities, and the 

 identification is certainly correct.

 (112). 



Geographic distribution. — New Jersey, Alabama, Mississippi.
