Desc. Shell nearly oval, rather short, obtuse at both ends, white ; 

 inner margin of the outer lip toothed; columellar lip forming a strong 

 flexuous pliciform tooth at the upper end, thickened on the outer edge, 

 depressed near the base, and forming a tooth-like fold at the lowest end, 

 both the canals very short. The outer lip of the only specimen I 

 have seen is rather sharp, and a few of the teeth extend from the inner to 

 the outer edge near the centre of the lip. I am not acquainted vdth its 

 locality,

Desc. Shell ovate, gibbose, white, pale lilac at the extremities* 

 the back raised into an obtuse transverse angle ; outer lip when full grown 

 much thickened, toothed on its inner edge: the glaze spread over the 

 outer part of the shell at its maturity, does not meet in the middle of 

 the back, the intermediate space is faintly transversely striated: two 

 singular small, flattened, white, brown edged, wart shaped excrescences, 

 one placed at each extremity of the back, distinguish this species from 

 all others. 



Not an uncommon species in the Indian Ocean ; the Ceylon and Isle of 

 France boxes generally containing several specimens. It is, however, 

 rendered interesting, as being the only shell with the singular tubercular 

 appendages noticed in its character and description. To these it is 

 , indebted for its name, and on account of them Montfort distinguished it 

 from Ovulum as a genus under the name of Calpurnus.
