C. testa ovatd, inflata, antice attenuate!,, postice sub-obtusd, Icevi : aperturd elongatd, 

 angustd, flexnosd, basi dilatatd, viw emarginatd ; columella obsolete plicalo-dentald ; labro 

 incrassalo, extus sub-marginato, intus regidariter dentato, antice compresso. 



Shell ovate, ventricose, swelled out in the middle, attenuated in front, rather 

 obtuse behind, smooth : aperture elongated, curved, narrow, but somewhat wider in 

 front, where it terminates in a short wide canal, obscurely notched. The outer lip 

 much produced, and the posterior extremity bent suddenly towards the apex of the 

 spire, forming between it and the posterior extremity of the body-whorl, an oblique 

 narrow groove, which represents the posterior canal found in some of the Cyprcese ; 

 the outer lip thickened, depressed on the surface, flattened in front on the inner 

 surface, where it joins the anterior canal, and presenting a prominent ridge along the 

 outer margin ; the teeth, which are short and placed on the inner edge only, become 

 obsolete on the flattened part of the lip. The columella presents four or five oblique 

 folds in front, and is obscurely dentated behind. 



This Cypraea occurs rather numerously in the calcaire grossier ; our English specimens 

 are generally of a larger size than those found in the French formations. 



Size. — Axis, 1 inch and 5-10ths, nearly; diameter, 1 inch: occasionally larger 

 specimens occur. 



Localities. — Bracklesham Bay, where it is common ; but the specimens are generally 

 distorted. 'French: Grignon, Parnes, Mouchy, Amblainville, Thury-sous-Chaumont, 

 (fide D'Orb.) The species is recorded by Brogniart and by Bronn as occurring at 

 Ronca (Vicent.). but the identity is questionable. Casts of Cypraese occur in the 

 sands of Rouge-Cloitre, St. Josse-ten Noode, Groenendael and Orp-le-Grand, in 

 Belgium, which also have been referred, although with doubt, to the present species. 

 The shells from Dax and St. Paul, which were described by Grateloup as belonging to 

 C. inflata, appear to belong to a distinct species, which D'Orbigny has named 

 C. pseudo-inflata ; and the shells from the Piacentin, referred by Brocchi to this species, 

 also appear to be distinct, and have been described by Sismonda under the name 

 C. labrosa.
