the latter which appeared to me to contribute to a better knowledge 

 of them. 



Macacus melanotus. 



This Ape proves to be a native of Borneo. It was first described 

 under the name of Papio melanotus, by Ogilby, in our 'Proceedings ' 

 for 1839, p. 31. The typical specimen, which is half-grown and in 

 the British Museum, was said to have been brought from Madras ; 

 but for some time past this has been considered very doubtful, as no 

 other specimen has been found in any part of continental India. A 

 second example, without known history, an adult male, was purchased 

 of the Zoological Society in 1866 *. The third specimen, now re- 

 ceived from North-western Borneo (mainland opposite Labuan), is 

 quite young, only 12 inches long. The sides, abdomen, and legs are 

 of a light chestnut-colour ; the tips of many hairs shining golden. In 

 older examples this chestnut-colour is limited to a portion of the hairs 

 only, and more and more replaced by blackish brown. The middle 

 of the head and back and upperside of the tail are black mixed with 

 brown. The longitudinal median crest of long hairs on the head, 

 characteristic of the species, is well indicated. Of particular interest 

 is the tail, which in our specimen is perfect, and which in both the 

 other examples (menagerie specimens) is mutilated. It is 3 1 inches 

 long, covered with short hairs, and extremely slender in the last two 

 thirds of its length ; so that the loss of this portion in specimens kept 

 in captivity can easily be accounted for. 



GYMNURA RAFFLES1I, Var. CANDIDA. 



All the specimens received from Labuan, the mainland opposite to 

 Labuan, and Sarawak differ from the typical form in being of a white 

 colour, only a part of the longest and strongest hairs on the trunk 

 being black. The head, legs, and tail are pure white. As no struc- 

 tural differences can be discovered either in the skull, or dentition, or 

 any other part of the body, I consider it sufficient to distinguish this 

 form as a merely local variety. 



TUPAIA. 



Having received two species of this genus from Borneo, I have 

 examined the series of specimens in the British Museum, which is 

 tolerably complete, at least as regards species. They may be divided 

 thus : — 



I. Species ivith grizzled hair on the hind part of the back and tail. 

 A. Large species. 



1. TUPAIA FERRUGINEA (Raffl.). 



The specimens in the British Museum are from Malacca, Pinang, 

 Singapore, and Sumatra ; according to Schlegel this species occurs 

 also in Java and on the west coast of Borneo (Pontianak). The 

 skull is distinguished by a large oval vacuity in the zygomatic arch.
