2. Notes on Rhinoceros sumatrensis, Cuvier. 

 By John Anderson, M.D., Calcutta. 



[Eeceived January 13, 1872.] 



Having had an opportunity of examining a living specimen of this 

 species, I have drawn up the' following remarks, which may prove of 

 sufficient interest to merit a place in the Society's « Proceedings.' 



The specimen examined is a young female that strayed into Cb.it- 

 tagong in February 1869, when it was captured, and where it has 

 remained till within the last few weeks. It has been brought to 

 Calcutta by Mr. Jamrach of London, to whom I am indebted for 

 my examination of this interesting animal. Mr. Jamrach has pur- 

 chased it in the hope of being able to take it to London alive, where, 

 if he succeeds in his endeavour, it will doubtless attract much interest, 

 as no living example of this species, that I am aware of, has hitherto 

 reached England. The uncertainty, however, of this enterprise in- 

 duces me to forward to the Society these notes, together with an un- 

 questionable representation of the external characters of this species. 



There is no previous record of this Rhinoceros having been found 

 so far west* as Chittagong, about 92° E. long. ; but I see nothing 

 remarkable in this, as the fauna of Eastern Bengal is pronouncedly 

 Malayan. It is also probable, as Blyth observes, that it ranges into 

 Assam, because, while at Bhamo in Upper Burniah, I was informed 

 by an intelligent native that two-homed Rhinocerotes are found in 

 the Mogonny district, which is close to the confines of Assam, and 

 as far north as the twenty-sixth degree of north latitude. This same 

 informant also assured me that he had seen at Mogonny a Rhino- 

 ceros-head with three horns. 



The female which forms the subject of these observations is about 



* In the 'Mammals of India' it is stated to have been shot at as high a lati- 

 tude as 23° N., near Sandoway, which, however, lies only between the 18th and 

 lDth parallels N.
