 tion of each whorl exhibit a striking contrast with the deep 

 jet black ground of the shell.

Sab. Island of Capul, Philippines (found under stones at 

 low water) ; Cuming. 



The general aspect of this shell is very similar to that of 

 the preceding species ; upon examination it will be found, 

 however, to be of a thinner and more slender structure, 

 whilst the sculpture is of a smaller pattern, and the colour 

 altogether different.
