386 Mr. Gray's Monograph on the Ci/praidce. 



Shell ovate oblong, blueish-grey, with three obscure bands, and 

 closely speckled with greenish fulvous dots ; middle of the back 

 marked with a large irregular, squarish, brownish spot; spire 

 slightly concave, partly covered ; base flattish, yellowish-white ; 

 edge rounded, except at the front extremity, which is margined on 

 the sides; aperture large, whitish; teeth of the inter lip small, 

 distant, except two large ones in front ; columella plaited ; teeth 

 of the outer lip large, blunt^ distant ; inside purplish. Axis }i, 

 diameter r~^ of an inch. 



This shell varies first, in having no dorsal spot, in being more 

 ovate, and in the base being yellowish flesh-coloured, with the 

 mouth yellow, when it is the C, Ovum of Gmelin, and secondly, 

 in being ovate oblong, without any dorsal spot, but having two 

 l)lack spots, one on each side of the upper part of the anterior 

 extremity, with yellow flesh-coloured base and sides, and whitish 

 mouth. 



When barked is somewhat like C. cylindrica, from which it may 

 however always be distinguished by its mouth and rather smaller 

 spire. 



I cannot willingly regard these varieties as distinct species, for 

 some specimens in the same parcel have, and some have not, the 

 dorsal spot, on which Linnaeus founded his specific character ; nor 

 nor can I consider that the spots at the end are of sufficient im- 

 portance, for I have observed that they gradually disappear ; or 

 At least, I have found some specimens with only one on pne side 

 and none on the other, and I do not find any other differ- 

 ence in the teeth, or in the essential form of the shell. Perhaps 

 the C. Ovum of Gmelin is the most distinct.
