134 EOCENE MOLLUSCA. 



Among the fossil Cyprasae found in the Paris basin, is one belonging to the present 

 section, which Lamarck considered to be identical with the recent Gyp. pediculus, but 

 which, M. Deshayes, in his 'Description des coquilles fossiles,' &c, has shown to be 

 distinct, and has named C. Lamarchii. Mr. Webster (loc. cit.) has recorded a fossil 

 cowry as occurring at Highgate, and at Stubbington, which he also refers to C. pediculus. 

 I have not met with any Cypraea belonging to this section, either from Stubbington or 

 Bracklesham Bay ; but it is not improbable that the Highgate specimen mentioned by 

 Mr. Webster belonged to the present species, which, however, is more globose than 

 C. Lamarc/cii, with a wider aperture, and more numerous transverse lines. 



Size. — Axis, rather more than 3-10ths of an inch ; diameter, 3-lOths-of an inch.

C. testa parvd, ovato-oblonyd, ventricosd, antice attenuatd, canaliculatd, viiv emaryinatd, 

 transversim lineatd ; lineis numerosis, tenuibus, irregularibus, sulco dorsali, sub-mediano, 

 obscuro, interrupts ; aperturd anyustd, lineari ; labro involute). 



Shell small, ovately oblong, ventricose, attenuated towards the anterior extremity, 

 with a short canal, slightly notched in front, and covered with transverse ridges, 

 interrupted on the back by an obscure, nearly medial sulcus ; ridges slender, sharp- 

 edged, numerous (18 to 20), irregular ; aperture linear, narrow ; outer lip incurved. 



This Cypraea is not so pyriform as C. platystoma ; the apex is not so elevated, the 

 transverse ridges are less regular and not so numerous, particularly over the outer lip ; 

 and the aperture is linear without any posterior curve. The more globose form, the 

 elongated aperture, and the posterior canal of C. Wetherelli, distinguish it from that 

 species. 



I am indebted for this cowry to Mr. Prestwich, to whom I have dedicated it. 



Size. — Axis, rather more than \ of an inch; diameter, 2-10ths of an inch. 



Locality. — Basingstoke .
