white, devoid of all sculpture, and of an elongated oblong figure, 

 that is acutely contracted above, and gradually terminates below 

 in a short canal. The posterior sinus of the outer lip, which is 

 acute, simple, but little projecting, moderately arched, and more 

 disposed to coil inward than to expand, is rounded and rather 

 large. There is a slight incurvation at the superior portion of 

 the columellar lip, which below is almost straight or slightly 

 convex. The length is nearly five lines and a half; the breadth 

 about the eighth of an inch : it inhabits the West Indies.
