1. RHINOCEEOS. 303 



In the Museum of the Royal College of Surgeons there is the 

 skeleton of an adult animal (no. 2969 a) that fonnerly had the long 

 front horns of an African Elephant placed on its nasal bones, which 

 Mr. Flower, the present Curator, has properly removed. 



There are also skulls of half-grown or female animals, with the 

 seventh grinder just showing itself, of this species (nos. 2975, 2976), 

 with a large oblong erect lachrymal. 



AU these skuUs have thick intermaxillaries, and the front of , the 

 upper jaw, at the base of the intermaxUlaries, is not suddenly con- 

 tracted. In the three adult skuUs it is 3 inches 9 lines wide ; ia 

 the younger skuU in the CoUege of Surgeons (no. 2975) it is 3 inches 

 3 Unes. The width of the diastema between the cutting-teeth and 

 the front premolar is 2 inches 6 lines in all the specimens. 



There is a stuffed specimen and a moimted skeleton of a young 

 animal, just showiag the horn, in the Free Museum at Liverpool, 

 and the skuU of a second of the same age. These two animals died 

 on the voyage from Calcutta to Liverpool, were named R. sondaicvs 

 by Mr. Blyth, and preserved by Mr. Moore, the energetic Curator 

 of that Museum. Mr. Blyth informs me there is a skeleton of 

 R. sondaicus in the Anatomical Museum of Guy's Hospital, called 

 R. indicus. 



The Indian Ehinoceroses are long-lived. Mr. Blyth speaks of a 

 pair that lived about forty-five years in captivity in Barrackpoor 

 park : they were exactly alike in size and general appearance ; they 

 never bred ; there is no difference in the horns or form of the skulls 

 in the two sexes (Blyth, J. A. S. B. xxxi. p. 155). 



The foetal skuU of R. unicornis (no. 722 D) in the British Museum, 

 received from Mr. Bryan Hodgson, is short ; the brain-case is oblong, 

 ovate, swollen, and convex behind ; the nasal bones are about as 

 long as they are broad at the hinder edge, transversely convex above 

 in the middle of their length and in the deep central groove in front 

 above ; the nasal cavity is long, high, and wide ; the nasal bones 

 are three-eighths of the entire length to the occipital crest ; the 

 length of the skull from the nasal to the front of the orbit is two- 

 fifths of the entire length to the occipital condyles. The iiiter- 

 maxillaries are weU developed, rather thick and short ; they each 

 bear two blunt teeth, scarcely raised above the alveolus, the first on 

 each side is much larger and thicker than the hiader one, which is 

 small and conical. There are three grinders developed on each side, 

 the second and third being rather more developed than the small 

 front one. There appears to have been a fourth tooth on each side 

 more or less developed ; but it and the cavity have been lost. The 

 palate is narrow and deeply concave, nearly of equal width, but the 

 sides are less erect and more expanded behind than in front ; the 

 front edge of the hinder nasal aperture is narrow, and rather in 

 front of a line even with the hinder edge of the third grinder ; the 

 length of the palate from the front edge of the intermaxiUaries is 

 rather more than from the end of the palate to the suture between 

 the basal sphenoid and the basal occipital bone. The vomer is cora^ 

 pressed, and forms a well-marked broad ridge, which is much higher
