160 A Memoir on the living Asiatic Species of Rhinoceros. [No. 2, 



iKDicus 1 ft. (or even a trifle more), — in sondaicus 9 in. Breadth 

 of bony interspace between the tusks of the lower jaw, — in rNDicus 

 \\ to If in., — in sondaictts f to 1 in. These measurements are taken 

 from exceedingly fine examples of both species. 



Sir T. Stamford Eaffles asserts, of Eh. sitmatrAjS'tjs, 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 

 Smnatran individuals ! Baffles further remarks that — " Dr. Bell's 

 description and representation of this animal are extremely correct. 

 The skin of the Sumatran Rhinoceros," 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, 268.) In Mr. C. J. Andersson's ' Lake Ngami' (2nd 

 edit., p. 263), the same is remarked of one or more of the ordinarily 

 two-horned Rhinoceroses of Africa. This traveller writes — " I have 

 met persons who told me that they had killed Rhinoceroses 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 Eh. tichorhintjs of N. Europe and 

 Asia. 



Bell further mentions, of Eh. suit ate antjs, 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 Planches des Mammiferes, less so in Bell's 



fio-ure in the Phil. Trans., and in that by Dr. Salomon Muller ; and 



it is well shewn about the joivl and base of the lower jaw of our 



stuffed skin of the head of an adult female. In Dr. S. Mtiller's 



fio-ure 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.
