 subangular volutions, each marked by six strong longitudinal 

 folds or varices, which are spirally arranged, those of one volution 

 being a little behind the corresponding one of the preceding 

 volution, the whole making about one-fourth of a turn in the 

 length of spire; canal long and straight, making with the narrow 

 ovate aperture, rather more than one-half of the entire length; 

 surface marked by somewhat alternating revolving lines, strongest 

 on the largest part of each volution.

AldricW s original descriptio7i. — "Shell broadly ovate, apex 

 pointed; whorls ten, the first five very small, smooth, the sixth 

 partially so passing into the adult stage; adult whorls with six 

 strongly developed transverse ribs which are angular at the per- 

 iphery; spiral sculpture coarse, more so at the junction with the 

 ribs, making each one to terminate in a rounded and beaded 

 projection broader at the point than elsewhere; columella straight, 

 slightly thickened at the lower half of the aperture; canal straight. 



"Locality. — Matthews' Landing, Ala." 



Fragments indicate that this species often attains a length of 

 four or five inches. In adults the peristome has a broad sinus 

 at the carina and the lip is there slightly reflected.
