FAUNA ANTIQUA SIVALENSIS. 



several independent inquirers, we may expect that, amidst 

 the immense quantity of bones which are continually met 

 with, the debris of this animal wiU be found in sufficient 

 abundance to lead to a knowledge of all the main points of 

 its osteology. From the form of the posterior molars we 

 have designated the animal Tdraconodon, with the specific 

 name of magnum, from its large size,^ which apjDears nearly 

 to have aj)proached that of the Hipj)oj)otamus and the Indian 

 Rhinoceros, as wiU be seen by a comparison with the corres- 

 ponding teeth of these animals.^ 



The occurrence of such an animal is, perhaj^s, not more 

 than might have been looked for. The discovery by Crawfurd 

 and WaUich, on the Irrawaddi, of two new species of Masto- 

 don, peculiar to India, gave reason to expect corresponding 

 new results among other Pachyderniata. Our researches in 

 the Mui'kunda have borne out this idea. The Tetraconodon 

 magnum is not the only new animal which we have found in 

 this vast Golgotha ; but we have not yet had the opportunity 

 or leisure of examinmg the bones in detail fit to make the 

 results public. We can only allude to them at present. 

 Among others, we have several portions of the jaws and heads 

 of what we believe to be a new species of Hippopotamus, in 

 which the canines, instead of being furrowed longitudinally 

 by a deej) fossa on the inner side, have the sides meeting in- 

 wards in a sharp edge. 



The fragment of the jaw of the Tetraconodon was got by a 

 native collector emj^loyed by Lieuts. Baker and Durand, and it 

 is now in the joint collection of these gentlemen, who have 

 kindly permitted us to make use of it for publication in the 

 journal of the Asiatic Society. 



' From rirpa, kZvos, and oSovs. This 

 name must not he confounded with the 

 Titraccnilodon of some later American 

 autliors, apj)lied to individuals (?) of the 

 large Mastodon, ynth. incisives in the 

 lower as well as the upper jaw. 



^ The measurements, which were 

 omitted in the manuscript, have been 

 made by me in the Museum of the Royal 

 College of Surgeons and in the British 

 Museum, with the assistance of Mr. 

 Flower and Mr. Davis. — [Ed.]
