Reptilia. 



CrocodiUa - - Gharial — crocodile; both very closely corresponding with the existing 

 species now in the rivers. Lacertine remains indeterminable. 



Chelonia - - Emys and tryonix ; some of the fragments are of the most gigantic pro- 

 portions. Of the smaller varieties, nearly entire specimens have been 

 found ; upper buckler and carapax complete. My cabinet also contains 

 three heads, wanting only the occipital portion of the cranium. 



Pisces. 



Genera not established. 



Many other fragments have been found, but so imperfect as to render a 

 classification impossible. I may remark, that there appears to be no end 

 to the variety as well as quantity of these remains ; and we may expect to 

 do much, even in this remote region, in advancing the inquiries respect- 

 ing fossil zoology. 



Of each genus above mentioned, with the exception of the horse and the 

 carnivora, I have already almost perfect skulls. The bones of the body, how- 

 ever, appear to have been much broken and mutilated ; but it is a singular 

 fact, that from many places where the fossils have been found as mere debris 

 of fallen cliffs, fragments of bone have been obtained, which have admitted of 

 being joined, although the fractured ends were coated with carbonate of lime, 

 as if they had been fossilized separately. A beautiful example of this, is ex- 

 hibited in an almost perfect rib of an elephant or mastodon, which is forwarded 

 to the Society's Museum, and which consisted of no less than eight pieces. A 

 perfect humerus of a ruminant has been secured in this state; and the bones 

 of two hind legs, namely, the upper part of the metatarsal connected to the 

 lower portion of the tibia by the intermediate tarsal bones, with, also, the os 

 calcis entire, and all the smaller bones of the tarsus equally so. These remains 

 have belonged to an enormous animal, and, I believe, to the same genus as 

 that of a skull in my possession, and now under description by my friend 

 Dr. Hugh Falconer, of the Bengal medical service, and myself. Although 

 I refrain from zoological details, I must mention, that we have an animal 

 evidently forming a connecting link between the Pachydermala and Ru- 

 minantia, or between the Tapir or PaUeotherium, and the latter order of 

 mammalia. The hippopotamus of this sandstone appears to be a new species, 

 having six incisive teeth, besides other peculiarities, particularly in the pro- 

 portion of the bones of the head: the tusks also differ from those described 

 by Cuvier in his Ossemens Fossiles. The great depth at which the marl 

 lies beneath the upper strata, with the discovery in it of remains of the horse, 

 is an interesting fact. In the sandstone strata the remains of the horse are
