GREY CHALK MARL. 133 



Localities. Hamsey, OiFham. 



66. Inoceramus Cripsii. Tab. xxvii. fig. 11. 



Obovate, much depressed, with numerous concentric transverse ridges ; 

 beaks acuminated ; posterior side small, depressed ; anterior side ex- 

 panded ; hinge obUque ? 



The valves are of an obovate form, much depressed, and marked with 

 strong concentric ridges, somewhat obhquely disposed. These characters 

 distinguish the present species from the one above described. The beaks 

 are acuminated. The shell increases in width, but diminishes in depth as 

 it approaches the front. The posterior slope is small and depressed ; 

 the anterior, expands to form the hinge furrow. 



Casts of this species are common, but the shell is seldom preserved. I 

 have named it in honor of my esteemed friend John Martin Cripps, 

 Esq. M.A., and it is with great pleasure that I thus publicly express 

 my grateful acknowledgments for his kind exertions, in promoting the 

 success of the present publication. 



Localities. Eingmer, Hamsey, Offham. 



Several other species of Inoceramus occur in the grey marl, but the 

 specimens hitherto discovered, are in too mutilated a state to admit of 

 accurate determination. 



Fossil Fishes. 



The Grey Marl has afforded a few examples of the remains of fishes, 

 but these are exceedingly imperfect : fragments of bones, a few small ver- 

 tebrae, irregular patches of scales, and an inconsiderable number of teeth, 

 are the only specimens hitherto noticed. 



67. Eemains of a fish. Tab. xxxiv. fig. 10. 



This fossil was discovered at Hamsey; it shews vestiges of the tail, 

 and of one fin, but no conjecture can be formed of the genus of the 

 original.
