extremities ; the aperture rather contracted, and extended beyond 

 the spire ; the teeth of the outer lip large, distant, pale chesnut- 

 brown, and extended over the lip nearly to the margin, in a rib- 

 like form ; those of the inner lip, very indistinct and distant; the 

 columella flat, scarcely plaited. Axis |, diameter | of an inch. 



I have only seen decorticated specimens of this new and in- 

 teresting species, but the peculiarity of its base at once determines 

 it to be distinct from any other Cypraea. It certainly is very 

 nearly allied to the Cyprwa Algoensis, with which it agrees in 

 the front part of the inner lip being rugose, and it also has con- 

 siderable affinity to the Cvprwovula capensis, which was brought to 

 this country by the same person, but differs from it in the distance 

 of the teeth of the outer lip, and in the want of its substriated back.

Shell ovate oblong, with a large irregular, biight, yellowish- 

 brown blotch on the back, wliich is darker towards the edges, 

 containing an irregular bluish blotch in its centre; the spire is 

 prominent, covered ; the base nearly Hat, white ; the margin 

 thickened, rounded, and slightly produced at the extremitiis, 

 whitish purple on the upper part, and white beneath ; the aperture 

 is rather narrow; teeth of both lips rather large, nearly equal, 

 those in front of the inner lip being very little the largest; the 

 columella flat, deep, and largely plaited its whole length ; insii!e 

 purplish white. Axis i^j diameter i§ of an inch. 



This peculiarly coloured species was first described by Mr. W. 

 Swainson. Lately it has become a not very uiiconunon shell, 

 whether from fresh iniportations or from the breaking up of the
