DESCRIPTION. 



The general outline of this shell resembles that of the Cy- 

 •prcea Mauritiana, or Cypraa caput serpentis, being triangu- 

 larly gibbous, ovate, with the margins thickened, dilated, and 

 angular ; base somewhat flattened and slightly convex. The 

 color on the back much resembles that of the Cyprcsa Mau- 

 ritiana ; the spots are less and of a lighter color. The thick- 

 ened sides are marked with dark brown spots, and there is also 

 a large one on the center of the pillar lip. Teeth dark brown. 



REMARKS. 



Burrow says that the variety described by him might, with- 

 out impropriety, form a distinct species ; and indeed the pre- 

 sent shell, though larger, much more resembles Cypraa caput 

 serpentis, than it does the common specimens of Cypraa 

 fdrabica.
