curves backward and terminates over the blade-bone in the latter. 

 In li. wndaicus the neck-folds are less heavy and pendulous, 

 and the posterior plait which crosses the buttock from the base 

 of the tail is less extended, not reaching to the great vertical 

 fold anterior to the hind-quarters, as it does in R. indicns. Of 

 numerous skulls examined of both of them, those of each varying 

 considerably in contour, the width in some being conspicuously 

 greater than in others, the depth of the ascending portion of the 

 lower jaw — from the condyle to base — averages twelve inches in 

 adidts of R. indicus, and never exceeds nine inches in R. soudaicus. 

 The length of skull from occijDut to tip of united nasal bones 

 (measured by callipers) is, — in R. indicus, two feet (half an inch 

 more or less, English measure) ; in R. soudaicus, a foot and three- 

 quarters at most. Breadth of bony interspace between the tusks 

 of the lower jaw, — in R. indicus, one and a half to one and three- 

 quarters inches ; in R. sondaictis, three-quarters to one inch. The 

 skulls of R. sondaicus examined were from the Bengal Sundarbans, 

 the Tenasserain provinces, and Java ; and it was from a Javanese 

 skull that the illustrious anatomist, Cowper, first discriminated it 

 as a distinct species from the others ; the same individual skvdl 

 being: figured in the Osseinens Fossiles of Baron Cuvier, who, in 

 that work, rightly indicates the animal as being a little smaller 

 than the other {d'une taille un jmi moindre), and as otherwise much 

 resembling it ; but in his subsequently published second edition of 

 the Rtgnc Animal, while mentioning the particular distinction of 

 the great neck-fold, he refers to his brother's figure in the Planches 

 des Mammiferes, as illustrative of his R. Javanas. Professor Schirz, 

 however, gives the species of Frederic Cuvier as R. Javanicus. 



But the late Dr. Horsfieid had previously well figured the 

 animal, in his Zoological Researches in Java, as R. sondaicus of 

 Cuvier, and by the same name it has since been figured and 

 described in the great Dutch work of Dr. Salomon Miiller and 

 Professor Senuninck. Now M. Frederic Cuvier's figure of 

 his supposed Javanese Ehinooeros represents, most decidedly, a 

 young animal of the Asiatic Two-horned Rhinoceros, which does 

 not inhabit Java ! And it is a better figure of the latter than the 

 one which he gives as representing that two-horned species. Both 

 are copies of drawings by native artists, sent by MM. Diard and 

 Dusancel ; and in the former instance the posterior horn had been
