1880.] PROF. FLOWER ON THE SKULL OF A RHINOCEROS. 69 



Gibbons {Hylohates) might be interesting, and also, if it could be 

 managed, a Proboscis-Monkey {Semnopithecus nasalis). Adults of 

 this, however, invariably die within a few hours after capture ; and 

 young ones, though tame enough, are too delicate, as, with every care, 

 they rarely survive for a week. Young bears also seem delicate, and 

 a change of diet from sugar and milk to boiled rice killed my last in a 

 day. Tangalungas (a sort of Civet), Gymnuras, Argus Pheasants, 

 Nicobar Pigeons, Brush-Turkeys {Megapodius), and Hawks are among 

 the specimens brought in ; and I have had several Pittas as well. 

 Snakes, Tortoises, Crocodiles up to 1 6 or 1 7 feet in length, and Moni- 

 tors may always be had ; and Orang Utangs (young) would come if I 

 offered a reward for them. The full-grown Orang it is, of course, 

 impossible to catch. I could send any of these things free to Singa- 

 pore if you had any one there to receive and forward them on account 

 of the Society. I have a young Sooloo Deer, a very pretty spotted 

 animal, given me by the Sultan of Sooloo ; but I hardly feel inclined 

 to part with it. The ordinary large Banian Red Deer also some- 

 times comes to me ; the last time I was at sea we gave chase to 

 one in the steamer, and caught it and hauled it on board alive ! 



"You may be interested to hear that I am sending home this mail 

 a skull and skin of head of a two-horned Rhinoceros. The second 

 horn is certainly not very big, but I did not know before that there 

 was a two-horned species of Rhinoceros in Borneo." 



Prof. Flower exhibited the skull in question, which had been 

 kindly lent to the Meeting for examination by Mr. Alfred Dent, and 

 made the following remarks : — 



" In some notes on the cranial and dental characters of Itlmioceros 

 (P. Z. S. 1876, p. 450), I identified the skull of a young animal, 

 obtained in Borneo by Mr. Lowe, of Labuan, and added in the pre- 

 vious year to the British-Museum collection, with R. sumatrensis. 



" The present additional evidence of the existence of a Rhinoceros 

 in Northern Borneo consists of a skull and the skin of the face, 

 with both horns, of an aged individual. The molar teeth are worn 

 down almost to their roots, yet the two lower incisors are retained. 

 This is noted because these teeth are absent in the specimen from 

 Malacca, which formerly lived in the Society's Gardens, and in 

 another in the Brussels Museum (cf. Garrod, P. Z. S. 1873, p. 92). 

 The praemaxillae are also united with the maxillae, though the line of 

 suture is distinctly visible. In size and all essential structural cha- 

 racters the skull agrees with that of the female from Sumatra in the 

 Museum of the Royal College of Surgeons, No. 2933, except that it 

 is shghtly smaller : and the teeth are also relatively smaller ; but their 

 extremely worn condition interferes with minute comparison. It 

 differs greatly from the specimen from Tipperah, described in P. Z. S. 

 1878, p. 634, which was especially characterized by the breadth of 

 the frontal region and the large size of the teeth. I should consider 

 the present specimen to be quite a typical example of Rhinoceros sive 

 Ceratorhinus sumatrensis. The only further point of interest to 

 note is that the mesethmoid cartilage is ossified to a greater extent
