Sliell ovate, ventricose, white, ornamented with a few scattered 

 blackish-brown spots, especially on the sides; back clouded with 

 unequal bluish spots; dorsal line yellowish; sides thickened, 

 rounded ; base white, narrow, with a keel-like ridge on each 

 side shelving towards the aperture ; aperture scarcely larger in 

 front, orange red ; teeth distinct, blunt, white ; columella plaited, 

 front rather concave. 



Obs. This shell, on account of the various appearances which 

 it assumes before it arrives at perfection, would be difficult to 

 distinguish, were it not for its orange mouth and white teetli. 



When young the shell is pale yellow with three double bands : it 

 becomes whiter, and ornamented with various sized fulvous spots ; 

 after which is deposited a white coat, which is spotted with 

 broM n, making the fulvous spot appear bluish through it.
