Cab. Cuming. Unique. 



Remarkably and very distinctly characterized by the two rows of 

 small tubercles which encircle the whorls. The shell is otherwise 

 of an uniform white glassy colour, which might be attributable to its 

 condition.

 Hab. Straits of Malacca; in seventeen fathoms, among mud. 

 Cab. Belcher. 



The description is drawn up from a somewhat young specimen, 

 and the mouth and last whorl have not yet attained their full deve- 

 lopment. The character of the shell is however very conspicuous. 

 In this genus the last whorl will be found very frequently to offer 

 decided features, and becomes a valuable aid in the diagnosis.

 nitidd, pallidd; anfractibus subplanulatis , longitrorsum recte plico- 

 costatis, superne lined impressd cinctis, interstitiis Icevigatis ; an- 

 fractu ultimo pallide lineato. Axis 11 lin.
