DESCRIPTION. 



SHELL minute, ovate-conical, with a pointed apex, of a 

 yellowish-green color, apparently smooth, but when exa- 

 mined by a considerable magnifying power, is found to be 

 thickly pitted with dots of unequal size and irregularly 

 disposed. There are four or five narrow, tumid whorls, 

 separated by a profound suture. The aperture is ob- 

 liquely semi-oval, and has a posterior lamellar tooth 

 winding within the shell, a tooth on the columella, and 

 another a little to the right of the basal apex. A small 

 umbilical opening is covered by the reflected columellar 

 lip, and the outer lip is slightly everted. 



Length of the axis one-twelfth of an inch.
