Fossil Shells discovered by Capt. Hay, \st European Regiment, in the 

 neighbourhood of Bajgahy Afghanistan."^ 



The fossil shells of which the accompanying are rough sketches, were 

 all found by myself in the range of mountains between the Dundan, 

 Shikun, and Karekotal passes ; in fact nearly the whole at Bajgah. The 

 formations in which they are found are so various, that I shall leave 

 better geologists to describe them, but they are chiefly found in con- 

 torted strata. 



No. 1 . a and b. two views of the same shell. 



2. Upper and under views of, apparently, the inhabitant of a 

 shell ; edges carinated : it is imperfect. 



3. Tuberculated, and considerably depressed. 



4. Plagiostoma? 



5. A fragment only. 



6. Gryphaea. There are no less than six species of Gryphaaa 

 (I think) found here. 



7. Puzzles me. In appearance it is a Haliotis ; but I have 

 seen some specimens with the remains of a second valve ; in 

 which case it would approach the Gryphaea. 



So many of the Gryphaea being found here, would argue that 

 the water had formerly been of a considerable depth. Mass- 

 es of them are found, and apparently adhering to the rocks, 

 which they cover so thick and regularly, as to be quite a 

 coat of mail. 



8. Apparently a Univalve. 



9. 10, 11, 12. Fragments of Bivalves. 



13. Univalve costated. 



14, 15, 16, 17. Bivalves. Specimens of 16 very perfect and closed. 

 18, 19, 20, and 21. Outlines of four species of Gryphsea ? all 



of natural size. 



* Note. — The publication of these drawings has, I regret to say, been long 

 delayed owing to circumstances I could not controul. The fossils whence 

 these are taken " with many other valuable collections of geological speci- 

 mens," says Capt. Hay, "and all my drawings," were lost when H. M. 

 Shah Shooja's 4th Regt. of Infantry retired from Bajgah.
