130 EOCENE MOLLUSCA. 
According to the strict rules of nomenclature, the specific name oviformis ought, 
perhaps, to be retained for this shell; but the species which occurs not unfrequently at 
Highgate and the neighbouring localities, and which is figured on the same plate, is 
so generally known as C. oviformis, that I have applied the name to that species. 
Size.—Axis, 3 inches and 1-10th; diameter, 2 inches and 2-10ths. 
Localities —Highgate, where it is very rare; Bracklesham Bay, where it is not 
uncommon.

C. testa globosd, levi, antice rostratd, vie emarginatd ; aperturd sub-rectd, angustd, 
postice sub-canaliculatd ; labro inflewo, compresso, ints dentato, dentibus numerosis, Sere 
equalibus ; columella dentato-plicatd, antice compressa. 
Shell globose, smooth, witha short, straight, rather narrow canal; scarcely notched 
in front; aperture nearly straight, narrow, terminating posteriorly m an obscure 
canal; outer lip broad, compressed, curved inwards, with numerous regular teeth, 
nearly equal in size, placed on the inner edge; columella furnished with numerous 
pliciform teeth. 
The nearly globular form and short narrow beak of this exceedingly rare Cypreea 
distinguish it from all its congeners. The specimen from which the figures are taken 
forms part of Mr. Dixon’s collection, and is, I believe, unique. The specific name 
proposed by Mr. Sowerby having been previously used by Dujardin for a different 
species from the Faluns of Touraine, [ have substituted the present name for it. 
Size.—Axis, nearly 2 inches; diameter, 13 inch. 
Locality—Bracklesham Bay.

Shell ovate, ventricose, flattened beneath, attenuated in front, rather obtuse behind ;

sulcus formed by the suture: mouth nearly straight, very narrow, a little wider in 
front, produced behind, and presenting at each extremity a short canal, slightly notched ;
