Shell ovate, pear-shaped, pale blueish-grey, with three obscure 

 bands ; the base convex, white ; margin slightly thick- 



ened and rounded on the sides, and sharp towards the anterior 

 of the extremity, white, with small scattered purplish-brown spots, 

 and one larger one over the spire. Spire concave, partly covered. 

 Aperture rather narrow, white. Teeth, of the inner lip, narrow, 

 long, rather distant ; those of the upper part brown ; those of the 

 anterior, thicker, paler. The columella flat, plaited the whole 

 length. Outer lip narrow, shelving outward, except at the ante- 

 rior part, where it is margined and shelving towards the mouth, 

 with teeth rather lafge, and distant; inside greyish-tvhite. Axis 

 \^ ; diameter -j?^ of an inch. 



I possess only two specimens of this shell ; one of which is not 

 quite formed, and is of a pale whitish colour, with a distinct 

 broad fulvous ceintral band ; and the other is fully formed, but 

 unfortunately has the back completely decorticated : in this state 

 it is grey, with the obscure blueish bands and the central fulvous 

 one. I am therefore unable to give the true colour of the back, 

 ■tvhich I leave to be filled up at a future time. I have not the 

 slightest doubt of its being a distinct species, from its form, 

 which approaches most nearly to that of C. pyrum^ and from the 

 colour of its teeth.
