of Asiatic two-horned Blunoceros. 403 



since proved to differ, I did not examine those specimens so 

 critically as I should now do, though I retain the impression that 

 the adult is notably larger than the stuffed male in the British 

 Museum, or than the aged female of the same species which 

 lately died in the Zoological Gardens. The skeleton of a Su- 

 matran female in the museum of the Royal College of Surgeons 

 agrees in size with the last mentioned ; but although a very old 

 animal, it retains its front teeth, which the others had lost. But 

 the skull of a Sumatran male in the same collection indicates a 

 considerably larger animal, which may even be of a different 

 specific race, corresponding to Schlegel's figure ; but this is a 

 matter for further investigation, and to which I can only 

 recommend attention. The Leyden beast is certainly not so 

 large by a good deal as is the living R. lasiotis, which appears 

 to be still growing, and has much increased in size since its 

 arrival in this country ; but it is not likely to become so large 

 an animal as the adult of the lesser single-horned species 

 {B. sondaicus), of which a skull, said to be undoubtedly from 

 Sumatra, has lately been received at the British Museum. 



I was assured at Leyden by Professor Schlegel that E. su- 

 matrensis existed in Borneo ; but an anterior horn said to be 

 from Borneo, in the possession of Mr. A. D. Bartlett, would 

 seem to indicate a species of still more diminutive size than that 

 which I believe, with Mr. Sclater, to be the real sumatrensis 

 of Bell, the mere difference of size of horn being not the only 

 reason for suspecting that the Bornean rhinoceros will even- 

 tually have to be recognized as a peculiar species. 



I may also here mention that upon looking over a portfolio 

 of drawings at the India House, belonging formerly to the 

 Earl of Mornington (Governor-General of India and subse- 

 quently Marquis of Wellesley), I found two of single-horned 

 rhinoceros. One of these is a fair representation of a very 

 young individual of R. sondaicus ; the other — which, however 

 faulty in general outline (being much too deep in the body), 

 is finished elaborately as regards details — appears to me to 

 represent a peculiar and undescribed species. The folds of the 

 cuirass are the same as in both vndicus and sondaicus^ except 

 the one which crosses the nape in the latter, and is deflected 

 backward across the shoulder-blade in the former ; this one is 

 intermediate in its direction, for it is deflected backward much 

 higher upon the shoulder than is regularly the case in R. indicus. 

 The most remarkable peculiarity, however, consists in the 

 cuirass being throughout conspicuously studded with uniformly 

 small tubercles (as in R. sondaicus) , while the head and limbs 

 are represented as wrinkled, but the skin quite smooth and 

 devoid of tubercles, and in this respect contrasting remarkably 

 with the adjacent parts of the cuirass. I cannot think that
