whorls in the larger individuals, and becomes slightly granular 

 upon the body whorl. This last, which is furnished with an 

 additional revolving belt, is angulated at the commencement of 

 its basal declination ; its base is so compressed that it is flattened 

 or even concave. The mouth is very small, about a fifth of the 

 entire length, and somewhat square ; it terminates anteriorly in 

 a rather short but decided canal ; the pillar is dusky, very 

 strong, twisted, and, at its extremity, is rather obscurely and 

 very minutely plicated across in a spiral fashion. The length is 

 quite four lines, the breadth merely one. 



A rather scarce W. Indian shell ; introduced hy Montagu as 

 taken hy Laskey in the Sound of Midi.
