tered dots, and sometimes blotches of the same colour; the spire 

 flat; the base and sides white dotted; the edge slightly thick- 

 ened, rounded on the sides ; the extremities slightly produced and 

 margined on each side, and ornamented with two black-brown 

 spots at the upper part of each end ; teeth even, rather large, ex- 

 tending halfway over the lips on each side, into equal rib-like 

 striae ; columella flat, or slightly concave in front, plaited ; inside 

 brownish-purple : axis T 7 ^ , diameter -^ of an inch. 



This shell varies considerably in its colouring; being sometimes 

 plain blueish-white with a few small brown dots, and at others, 

 as in the variety )3., having one or two large fulvous brown irre- 

 gular blotches, the bands scarcely visible. This latter variety ap- 

 proaches very much in appearance to C. stolkla ; but it is instantly 

 to be distinguished from it by the teeth being white. It may in- 

 deed prove a distinct species when more of them are found, but 

 I have thought it best to keep it only as a variety, as I have only 

 seen one specimen, which is in Mrs. Mawe's private cabinet. 

 When the outer coat is w»rn ofF, the bands are at first black, but 

 become reddish when the back is still more worn. This species 

 sometimes loses the spots at one or both extremities, when it is the 

 C. Ursellus of Gmelin. Lamarck arranges C.felina as a variety of 

 this species ; this however is perfectly distinct. There exists a 

 considerable difficulty respecting the reference to the figure of the 

 French Encyclopaedia, and I have for this account only copied the 

 references of Lamarck.
