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 received 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| 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 RAFFLESII, 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 structural 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 with grizzled hair on the hind part of the back and tail. A. Large species. 1. T U P A I A F E R R U G I N E A (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. * " Macacus speciosus," spec, a, of the ' Revised List of Vertebrated Animals A the Gardens of the Zool. Soc' p. 16. Cf.
