represented, consists in the great skinfold at the setting on of the head of 

 R. indicus, which is at most but indicated in R. sondaicus. In skulls of 

 adults, however those of both species may vary in width and especially in 

 breadth anteriorly, the following distinctions are trenchant. Length of 

 skull, from middle of occiput to tip of united nasals, in R. indicus 2 feet 

 (half an inch more or less) ; in R. sondaicus If foot at most. Height of con- 

 dyle of lower jaw in R. indicus 1 foot or even a trifle more ; in R. sondaicus 

 9 inches. Breadth of bony interspace between the tusks of the lower jaw- 

 in R. indicus 1^ inch to 1| inch; in R. sondaicus | inch to 1 inch. These 

 measurements are taken from exceedingly fine examples of both species." 



Turning again to the 'Zoologist,' it is recorded by Mr. Arthur 

 Adams, at p. 7328 of the volume for 1861, tliat at Mew Bay, in 

 Java, near the Straits of Sunda, "the ground is literally ploughed 

 up by the tracks of these unwieldy brutes." The brutes in question 

 being beyond doubt this species, Rhinoceros soudaicus, no other 

 species inhabiting that island. 



I hope, if my life be spared a little longer, to revert to the 

 specific distinctions of rhinoceroses again and again; for much 

 remains to be investigated and satisfactorily explained; it is 

 sufficient to hint a belief, prevalent in all countries where two- 

 horned species occur, that they occasionally have three horns. 

 I need scarcely say that I know of no preserved specimen having 

 this peculiarity. 



The specimen now in the Gardens is from Java, and I am told 

 it has been purchased for the Society, at eight hundred pounds • 

 it is deposited for the present in the first compartment of the 

 elephant-house as you enter from the tunnel. I visited this animal 

 on the 21st March, fourteen days after his arrival, and was par- 

 ticularly struck with the comparatively slender character of the 

 head, which is much longer in proportion to its bulk than that of 

 Unicornis. The skinfolds are of a less massive character and 

 differ very considerably in outline and situation : there is par- 

 ticularly a saddle-shaped shield on the neck of Sondaicus of which 

 I see no homologue in Unicornis ; the back is thickly covered with 

 brown brislle-like hairs; a fringe of similar hairs is also observable 

 on the margin of the ear. The horn is little more than an apology, 

 short and amorphous, as though the poor beast had been long in 

 durance vile, and had worn away this instrument in its efforts to 

 escape. The flattened tubercles, which in the hide of Unicornis 

 have been compared to bolt-heads, are less, and less prominent on
