but longer ; the anterior end is narrower than the posterior extremity, 

 whilst in the S. Imbricata both ends are nearly equal. The imbrica- 

 tion of the lines of growth is strongly defined. 



Found with the preceding. 



Cardinia, sp. (C. Himalayana, Verch. nov. sp.) PI. VI. fig. 2. — 

 (Anthracosia, King.) ? f 



The lines of growth are deeply impressed and imbricated, and the 

 shell bulges a little between these lines. The hinge was not seen. 



Animals gregarious ; their shells occur heaped together in patches. 



Manus Bal, Koonmoo, Mutton ?, Rotta Ron. 



Cardinia, sp. (Cardinia Ovalis, Martin,)V\. VI. fig. 3. — (Anthracosia 

 King.) f 



A species more elongated than the preceding. Lines of growth 

 similarly disposed. Found with the preceding. 



Cucullcea, sp. PI. VI. fig. 4. 



A gregarious small shell, sometimes so abundant that it forms 

 masses of rock by itself. Lines of growth well defined, especially near 

 the margin. Hinge not seen. It is perhaps the young of some larger 

 shell. 



Found at Wean, Koonmoo and Ishmalabad in Kashmir and in the 

 Rotta Roh in the Punjab. 



Pecten, sp. PL IV. fig. 5. 



Small shell, perfectly smooth with the exception of a few lines of 

 growth. It is ornamented with painted dark lines, which radiate from 

 the beak to the circumference, increasing in width as they approach 

 the margin. The convexity is very small, and the ears small. 



Only one-valve specimens were ever found, through the shell is 

 tolerably common in the reddish limestone of Koonmoo in Kashmir. 



Found also in the Rotta Roh ? 



Aviculo-pecten Dissmilis, (I lent.) 



See M. de VernueiFs note. 



This and the following Aviculo-pectens are apparently identical 

 with the group of animals represented in England by the A. -Pecten 

 Arenaceus. They were gregarious and all lived together, and are now 

 found in a sandy somewhat friable limestone, in lenticular beds which 

 are evidently the remains of sandbanks near the shore. 



Our specimens of A, -Pecten Vissimilis are oval in shape, the
