DESCRIPTION. 
Sp. Ch. Size, rather small. Shell, quite thick and heavy. 
Striations, present. Whirls, nine. Examined forty specimens. 
Form of shell, a pointed cylinder, the first whirl being the largest, 
then each successive whirl is a little 
smaller to the fourth whirl, then the 
shell slopes gradually to the top, 
forming an angle of forty-five degrees. 
The striations are numerous, twenty- 
five to the first whirl, are not 
prominent, but are very regular, 
appearing like little half cylinders laid 
against the shell ; they are thus 
rounded, and are highly polished, 
without any furrows whatever, and 
are about one half as wide as the 
interspaces between them. 
Aperture rather small, slightly 
contracted at entrance, and rather 
oval. Lower tooth prominent, about .04 high, and twice as long as 
high ; not elevated, and set back about once its length from the frontal 
bar. Upper tooth quite well developed. 
Margin produced forward about as far as the diameter of the 
shell, is thickened all around, measuring about .03, is grooved, and the 
posterior portion is produced into a deep edge wdiich is not rolled 
bpckward. The frontal bar is comparatively thin, but completely 
interrupts the striations. 
Color of shell, dark flesh color throughout boty, externally and 
internally, extending also over the striations, paler on the apex and 
margin, with no indications of fleckings or markings of any kind.
