52 Mammals of Burma. [Xo. 1, 



its arrival in the London Zoological Gardens, early in 1872, was believed to 

 represent the Rhinoceros sumatrensis of Bell and Baffles ; but soon afterwards 

 another two-horned Bhinoceros was received at the same establishment from 

 Malacca, obviously of a different species, which proved to be the veritable R. 

 sumatrensis. Since its arrival, it has now (1873) considerably increased in size, 

 and it probably is not yet quite full grown. As compared with C. sumatrensis, 

 it is a considerably larger animal, with much smoother skin, of a pale clay- 

 colour, covered with longer and less bristly hair, the latter of a light brown 

 colour, as seen in the mass. The ears are placed much further apart at the 

 base, and are not lined with hair as in the other, but are conspicuously fringed 

 with long hair ; and the tail is much shorter and largely tufted at the end. 

 The horns are worn away, but if the species be truly assigned to C. crossii, 

 the anterior would grow very long and curve to a remarkable extent back- 

 wards, while the posterior horn would probably be short. A second speci- 

 men of an anterior horn, almost as fine as the one first described, has recently 

 turned up among the stores of the British Museum ; and I found a smaller 

 anterior horn of R. crossii in the Museum of the London Boyal College 

 of Surgeons, confirmatory of its peculiar shape. In this group the horns are 

 remarkably slender except at the base, and of much more compact texture 

 than in other Bhinoceros horns. I have reason to believe that this is the two- 

 horned species which inhabits the Arakan hills, those of northern Burma, 

 and which extends rarely into Assam ; and I think it highly probable that 

 the skull figured in Journ. As. Soc. B. xxxi. p. 156, pi. iii. f. 1, repre- 

 sents that of C. crossii (seu R. lasiotis), in which case the range of the 

 species would extend into the Tenasserim provinces. A detailed notice of the 

 individual sent to London has been given by Dr. Anderson.*

The Sumatran Bhinoceros is much smaller than the preceding species, 

 with a harsh and rugose skin, which is black, and clad with bristly black hairs ; 

 the ears less widely separated at base, and filled internally with black hairs ; 

 the muzzle anterior to the nasal horn much broader" ; and the tail conspicuously 

 longer, tapering, and not tufted at the end. Horns attaining considerable 

 length, and curving but slightly backwards, as represented in Journ. As. Soc. B. 

 xxxi. p. 156, pi. iv. f. 1.
