12. Pholadomya? Agassizi D'Orb. T. C. pi. 363. f. 1— 3? {Go- 



niomya caudata Agassiz.) 

 A fragment. Loc. Hythe. 



13. Corbula striatula Sow. M. C. t. 572. f. 2, 3. 



Loc. Atherfield, Peasemarsh, Hythe, Ingoldsthorpe, Maidstone. 



14. Tellina incequalis Sow. M. C. t. 456. f. 2.? 

 Loc. (Casts.) Parham, Atherfield. 



15. Tellina ? angulata Desh. in Leym. t. 5. pi. 3. ? 

 Loc. (Cast.) Peasemarsh. 



16. Tellina ? vectiana. Sp. nov. PI. 2. f. 2. 



T. testa oblonga, depressa, subingequilaterali, transverse 

 striata, striis regularibus, numerosis, postice rotundata, antice 

 cuneata, angulata, carinata. 



Lon. Oif unc. Lat. OJ unc. 

 Shell oblong, depressed, regularly and deeply striated trans- 

 versely, rounded posteriorly, and angulated anteriorly, where a 

 strong carination runs from the beak to the pointed extremity, 

 over which the strise pass and become slightly lamellated in the 

 larger specimens. Young shells have much the aspect of Venus. 

 Loc. In the Cracker bed at Atherfield, not uncommon. 



17. Corbis corrugata (Sphcera sp.) Sowerby, M. C. t. 335. 



Syn. Venus cordiformis Deshayes. Corbis cordiformis D'Orb. 



Cardium galloprovinciale Matheron. (according to D'Or- 



bigny.) 

 Loc. Atherfield. 



Note. The hinge of this shell being now known, the genus Sphccra must be 

 suppressed, and the species on which it was founded placed in the genus Corbis. 

 This was first shown by M. d'Orbigny, and a well-preserved hinge in the 

 Society's collection confirms his view. British specimens were identified by 

 that palaeontologist with the French Corbis cordiformis. 



18. Corbis ? fibrosa. Sp. nov. 



C ? testa transverse ovata, depressa, transverse sulcato- 

 striata, interstitiis longitudinaliter crenatis. 

 Lon. 0^ unc. Lat. 0^- unc. 

 I have applied this name provisionally to a species found at 

 Reigate, Peasemarsh, and Atherfield, but of which the specimens are 

 very imperfect, and not sufficient for the determination of their 

 true generic position. 



1 9. Lucina ? solidula. Sp. nov. PI. 2. f. 7. 



L. testa convexa, suborbiculari, requilaterali, concentrice 

 striata, striis regularibus ; umbonibus prominentibus. 



Lon. T 8 2- unc. Lat. nearly the same. 



Shell nearly orbicular and convex, regularly striated by lines of 

 growth, apparently very constant in form ; it is nearly allied to the 

 next species, and differs in being less globose and broader towards 

 the beaks. An Lucina Dupiniana D'Orbigny ? 



Loc Atherfield, Redhill, Peasemarsh.
