The district between the Jumna and the Sutluj consists of the same 

 series of shingle or conglomerate, sand, clay, and marl ; but the shin- 

 gle is less abundant, and differs in being composed of pebbles of va- 

 rious kinds of clayslate and quartz, and the marl is exposed only at 

 Nahun, where it contains the same organic remains as in the Kalowala 

 Pass. From Nahun to the plains there is a succession of sandstones 

 and clays, dipping on an average about 20° to the north. In the 

 neighbourhood of that town the sandstone is hard and used for build- 

 ing} but it becomes soft on approaching the plains. The clays are 

 stated to be more or less rich in Testacea, and the sandstone in re- 

 mains of Mammalia. 



The large collections of bones obtained by Capt. Cautley were found 

 partly lying on the slopes among the ruins of fallen cliff's, and partly 

 in situ in the sandstone; and he is of opinion that the former have 

 been, in a great measure, preserved by the sandstones in immediate 

 contact with the bones, being much harder and more ferruginous than 

 in the general mass. 



The following is a list of the remains which had been determined 

 at the time the memoir was written. 



Mastodon, elephant, rhinoceros, hippopotamus, hog, horse, ox, 

 elk, deer, several varieties ; carnivora, canine and feline ; crocodile, 

 gavial, emys, trionyx, and fishes ; and portions of undescribed mam- 

 malia. 



The remains of all these animals are in great abundance, with the 

 exception of the Horse and Carnivora ; but the bones of the head are 

 better preserved than those of the trunk or the extremities. Some- 

 times the fractured bones have admitted of being joined, though the 

 surfaces were coated with calcareous spar. 



In assigning an age to the formation composing the Sewalik moun- 

 tains, Capt. Cautley adopts the views of his friend Dr. Falconer, who 

 in a notice read before the Asiatic Society of Calcutta, considered the 

 deposit to be synchronous with that from which Mr. Crawfurd 

 obtained the remains near Prome, on the banks of the Irawadi, 

 there being an agreement in the organic remains. The author then 

 offers some remarks on the Mastodon elephantoides and M. latidens, 

 and in consequence of his having found jaws in which the front teeth 

 are not to be distinguished from the teeth of M. latidens, and the rear 

 from the teeth of M. elephantoides, he conceives that the distinc- 

 tion established on detached teeth will be found to be erroneous. 



March 23. — Henry G. Atkinson, Esq., of Grove End ; Henry Har- 

 pur Spry, Esq., of the Bengal Medical Service, Member of the Phy- 

 sical Class of the Asiatic Society of Calcutta, &c., and Frederick 

 Edwards, Esq., of Southampton Place, Euston Square, were elected 

 Fellows of this Society. 



A paper was first read, entitled, " A Description of various Fossil 

 Remains of three distinct Saurian animals discovered in the autumn 

 of 1834, in the Magnesian Conglomerate on Durdham Down, near 

 Bristol." By Henry Riley, M.D. and Mr. Samuel Stutchburyj and 

 communicated by Charles Lyell, Esq., P.G.S.
