160 A Memoir on the living Asiatic Species of Rhinoceros. [No 2, 
HTDicxrs 1 ft. (or even a trifle more),—in so> t datcus 9 in. Breadth 
of bony interspace between the tusks of the lower jaw,-—in indicus 
la to If in.,—in sokdaicus £ to J in. These measurements are taken 
from exceedingly fine examples of both species. 
Sir T. Stamford Baffles asserts, of Bh. sitmathanus, that “ the 
female has a larger and heavier head than the male, but is similar 
in other respects.” (!) This decidedly does not apply to the two¬ 
horned species inhabiting Burma; nor even to Bell’s figures of 
Sumatran individuals! Baffles further remarks that—“ Dr. Bell’s 
description and representation of this animal are extremely correct. 
The skin of the Sumatran Bhinoceros,” he adds, “ is much softer 
and more flexible than that of the Indian one, and is not, like it, 
corrugated into plates of mail. It has, however, some doublings or 
folds, particularly about the neck, shoulders, and haunches, rather 
more distinct and defined than in Dr. Bell’s drawing. The natives 
assert that a third horn is sometimes met with ; and in one of the 
young specimens procured, an indication of the kind was observed.” 
(Lin. Tr. XIII, 2G8.) In Mr. C. J. Andersson’s ‘Lake Ngami’ (2nd. 
edit., p. 203), the same is remarked of one or more of the ordinarily 
two-horned Bhinoceroses of Africa. This traveller writes—“ I have 
met persons who told me that they had killed Bhinoceroses with 
three horns ; but in all such cases (and they have been but few) the 
third or hindmost horn is so small as to be scarcely perceptible.” 
This seems a not unlikely character to have been developed more 
frequently in the great fossil Bh. tichorhinus of N. Europe and 
Asia. 
Bell further mentions, of Bn. sumatranus, that—“ The whole 
skin of the animal is rough, and covered very thinly with short black 
hair.” The latter is conspicuously represented in F. Cuvier’s portrait 
of the species in the Rlanches des Mammiferes , less so in Bell’s 
figure in the Phil. Trans., and in that by Dr. Salomon Muller; and 
it is well shewn about the jowl and base of the lower jaw of our 
stuffed skin of the head of an adult female. In Dr. S. Muller’s 
figure of what he styles an adult male (but the horns of which are 
quite small, as in the adult Martaban example before noticed*), the 
shoulder-plait is rather more strongly developed, especially towards 
* Can these animals, under any circumstances, occasionally shed and renew 
their horns, which consist only of a mass of agglutinated hair ? There is cer¬ 
tainly no physiological objection to the possibility of their doing so.
