C. testé ovatd, inflatd, anticé attenuatd, postice sub-obtusd, levi: apertura elongata, 
angustd, flecuosd, basi dilatatd, vie emarginatd ; columella obsolete plicato-dentata ; labro 
incrassato, extis sub-marginato, intus regulariter 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 Cypreee ; 
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 mner 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 Cypreea occurs rather numerously in the ca/eaire 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 iscommon; but the specimens are generally 
distorted.  Hrench: 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 Cypreese 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.
