Tliis shell having some characters in common with Cypr. Pe- 

 diculus, and as I have seen only this one specimen, I have felt it 

 difficult to separate it entirely from that species ; and on the other 

 hand it has characters so different, that I scarcely know how to 

 make it a member of that tribe : I have, however, placed it as Varietas 

 labiosa ; and should other specimens be found, I think it may be pro- 

 perly severed from its present associates, and retain that distinctive 

 appellation. 



CypRjEA vESicuLARis. Cypr. testd inflatd, subglobulosd, subtrigond, 

 rubelld ; costis transversis, approximatis, lavibus, concoloribus 

 supra columellam continuis ; aperturd ampld ; labro intiis albido, 

 dentato. 



Shell ovato-subglobose, inflated ; semipellucid, of a faint rose, 

 or flesh colour. Aperture very broad, a little longer than the spire. 

 Posterior part of the columella rather ventricose : the anterior forming 

 a broadish groove, the inner border of which is most prominent at 

 its middle, and the ribs passing through it terminate, at its posterior 

 part, in a serrated edge, the anterior part being even and forming a 

 smooth notch. Lip of a lighter colour than the ręst of the shell, 

 straight at its base, longer than the body of the shell, forming a very 

 slight notch as it joins the columellar side at the posterior extreinity, 

 and anteriorly a broader and deeper one between the beaks. Beaks 

 very slightly produced, and the anterior ones a little divergent. 

 Teeth numerousand even.about twenty on the lip, and about tvi^enty- 

 three on the columella. Ribs even, close, numerous, not j^rominent, 

 extending transversely across the sheU in parallel lines, and passing 

 entirely round the columella to its inner margin ; about eight of the 

 ribs terminate on the \ic, and consequently form no denticulations, 

 and almost alternately bet\veen the teeth from the anterior extremity, 

 some few terminate on the outer part of the columella. Ribs very 

 faintly marked on the back. No dorsal line. Margin a little thick- 

 ened. Spire visible, depressed. 



Length of the columella "475 of an inch ; of the lip •525 ; breadth 

 •450; height -350. 



Habitai. Cape of Good Hope. 



From Cypr. aperta it difFers by the anterior columellar beak being 

 divergent ; posterior end of the shell blunter and broader ; ribs 

 infinitely more numerous and even, and extending entirely over the 

 columella to its inner edge Avithin the aperture.
