nitente, pallida rosed, subnehulosd, antice saturatiore, last dlbidd ; 

 costis nunierosis, confertis, continuis, ad basin non interruptis ; 

 margine subincrassatd ; aperturd latiusculd ; lined dorsali nulld. 



Shell ovato-globose, posterior end rather obtuse and broad, of a 

 delicate rose (almost white) colour, somewhat clouded with very light 

 reddish brown, wiiich is deeper over the anterior extremity. Base 

 white, somewhat even. Aperture rather wide : teeth of the lip about 

 twenty-one, almost every alternate rib (about fifteen in number) 

 terminating between the denticulations just before arriving at the 

 edge of the Hp ; teeth of the columella about twenty-five, and about 

 seven terminate exterior to the aperture : columellar front grooved 

 along its entire length, inner edge of the groove slightly serrated, 

 forming a circular projection towards the anterior extremity, where 

 it is deepest and widest. Ribs slightly prominent, numerous, close, 

 extremely even and regular, extending continuously from the Up to 

 the inner border of the columellar groove, very few terminating on 

 the sides of the shell : false ribs few, and extending but little towards 

 the back. Anterior beaks rather wide apart, slightly produced : 

 beaks of the lip longer than those of the columella. Spire only trace- 

 able in the adult, and in the younger state forming a fine small point 

 or apex. Margin only on the lip side, and slightly thickened. No 

 dorsal line. 



Length -425 of an inch; breadth -350; height '325. 



The younger specimens of this beautiful shell are of a fine clear, 

 semipellucid, rose (almost white) colour, with the light reddish brown 

 markings at the anterior and outer extremity of the shell, and at the 

 point of the posterior beak of the lip, more conspicuous than in the 

 adult, while the cloudings are less observable. 



Habitat. Cape of Good Hope. 



From Cypr. Europaa it is distinguished by the following charac- 

 ters : greater convexity of the curvature of the inner edge of the colu- 

 mellar groove ; ribs and teeth much more numerous and even, and 

 on the lip almost every alternate rib terminates before arriving at its 

 edge ; shape more gibbous and obtuse posteriorly ; mouth wider ; 

 spire scarcely visible in the adult, and forming a beautifully minute 

 point in the younger individuals ; texture and colour of the shell in- 

 finitely more delicate.

Ctpk^a rubinicolor. Cypr. testd ovato-subglobosd, utrinque sub- 

 rostratd, rubelld, extremitatibus pulchre roseo-rubris ; labro in- 

 crassato, convexo ; costis aciitis, continuis, indivisis ; lined dorsali 

 nulld. 

 Shell ovato-globose,of a light red or pinkish colour; the four beaks, 

 particularly on the base, of a much deeper red. Base roundish. 

 Aperture and margins lighter coloured. Margins thickened, some- 

 what produced, in short, rather broad beaks. Aperture rather narrow, 

 and inner edge of the lip nearly circular. Columella somewhat ven- 

 tricose towards the middle, concave towards the anterior end : teeth 

 numerous and even; on the lip about twenty, proceeding across the 

 back, forming ribs, and continuing over the columella, pass through
