232 Journal of Travel and Natural History 



which originally appeared in the Geological Transactions in 1836, 

 and has been very judiciously inserted where it is now placed. 



The principal unpublished papers contained in the first volume 

 are: — i. The "Description of a Fragment of Jaw of an unknown, ex- 

 tinct Pachydermatous Animal, from the Valley of the Murkunda." 

 The fossil in question, which was discovered by Messrs Baker and 

 Durand, contained two posterior upper molars, which, in general 

 character, so closely resembled those of the Hippopotamus, that 

 the fossil had been assigned to that genus. Further investigation, 

 however, in Dr Falconer's hands, proved that it belonged to a 

 hitherto unknown genus, to which he assigned the name of ChcBro- 

 therhwi or Tetraconodon^ which presents characters apparently 

 connecting it with Hippopotamus Sus, and Anthracotherium. 



2. Another interesting unpublished paper, which was written 

 about 1839, is on the " Fossil Rhinoceros of Central Thibet, and its 

 relation to the Recent Upheaval of the Himmalayas." It aflbrds an 

 excellent example of the care and skill with which Dr Falconer 

 set about the unravelment of defective and uncertain evidence, and 

 of the mode in which he employed his results in the solution of 

 any question before him. 



3. The paper " On Chalicotherium Sivaleuse" was fully prepared 

 for the Geological Society in 1847, ^ii^cl it appears strange that 

 it was never presented. It is here given, well illustrated by figures 

 taken from the plates of the " Fauna Antiqua." 



Passing over the highly interesting papers on the fossil Camel, 

 and on Sivatheriu giganteum, that extraordinary link between the 

 Ruminantia as represented in the Camelidse, and the Pachydermata, 

 which have been already published, we come to an account of the 

 Colossochelys Atlas, perhaps the most extraordinary of all the 

 strange forms disclosed in the Sewalik Hills, and with respect to 

 which unfortunately no complete memoir was ever drawn up by Dr 

 Falconer. The Editor, however, has endeavoured, so far as in him 

 lay, to remedy this deficiency, and we are here furnished with a 

 very interesting collection of all the documents relating to this 

 suljject, illustrated by original figures drawn by Mr Dinkel from 

 the specimens themselves in the British Museum, so that but little 

 is left to be desired. 



The volume concludes with the " Oflicial Report of an Ex- 

 pedition to Cashmere and Little Thibet in 1837-8," which, though 

 drawn up thirty years since, is now for the first time jiublished, and 

 will, as the Editor remarks, doubtless still be read with interest.
