narrow, scarcely dilated in front; teeth small, blunt, close, brown, 

 the brown line extending into the concavity on the base ; colu- 

 mella smooth, front concave ; spire rather prominent, covered ; 

 inside whitish ; axis 1 |, diameter JL of an inch. 



This species, which has the form and aperture of C. Argus^ and 

 the colour and marking of C. lurida^ was first pointed out to me 

 by Mrs. Mawe, in her private cabinet, and I have since observed 

 it in the well selected cabinet of Miss Children. 



15, Cyprcea controversa. 



Testa ovato-elliptica, subcylindrica, pallide albido-cinerea, 

 vel cornea, obscure trifasciata ; basi lateribusque albidis ; margi- 

 nibus subincrassatis rotundatis, extremitatibus luteo, fusco, seu 

 nigro bimaculatis; apertura dentibusque albis, dentibus minutis. 



Inhabits. Mus. Crouch, Nost. 



Shell oval or oblong, elliptical, nearly cylindrical, gradually 

 raised towards the anterior extremity, very pale whitish flesh 

 colour, or gray, with three obscure bands, and speckled with 

 irregular white impressed dots ; base rather convex, subcylin- 

 drical, white, margin rather thickened, white or greyish, with a 

 yellowish line where it joins the body of the shell, slightly pro- 

 duced, and rounded at the two extremities ; extremities brownish 

 yellow, marked with two large brown spots, the anterior ones of 

 which are sometimes influent, and form one dark brown crescent; 

 Aperture scarcely dilated in front, teeth small, distant, white ; 

 columella smooth, front concave, slightly denticulated on the 

 innermost part; spire impressed, covered ; inside purplish white; 

 axis 11, diameter ^^ of an inch. 



This shell varies considerably in shape and ground colour, in 

 the two specimens which I have seen, the first being oval ellipti- 

 cal, whitish, and the other oblong elliptical, flesh-coloured ; but 

 the colour of the extremity, base, speckles, and spots, was 

 the same in both, and it is from these characters alone that it can 

 be separated from C. lurida^ to which it has very great afiinity, 

 and may perhaps prove only a variety, but I have agreed with 

 several of my friends in considering it as a species.
