Aring, Kelantan, 23rd Aug., 1899. This Monkey, which is of a clear ashy grey on the back, white below, with dark hands, feet, and tail, agrees with the example from Klang referred to by Mr. Thomas (P. Z. S. 1896, p. 72) as being identical with Cantor's S. albocinereus, which in Dr. Anderson's opinion, is synonymous with S. siamensis of Muller and Schlegel. Under the name siamensis Dr. Anderson gives a description of the present species ; but on reading Miiller's original description I find siamensis to be a dark-coloured Monkey, and there are several specimens in the British Museum of a dark brown Monkey, rather smaller than the specimen under consideration, which agree fairly with Miiller's description and are labelled siamensis. There is therefore no alternative but to allow7 Cantor's name to stand for the present. Cantor's type was founded on a young specimen, but he remarks that when adult it is hardly to be distinguished from S. obscurus; this remark, however, hardly seems to hold good, the present specimen being fully adult and yet showing no such resemblance. 5. SEMNOPITHECUS sp. inc. a. 8 juv. sk. Biserat in Jalor, 26th May, 1899. This specimen is very young and shows no distinctive features by which, with our present knowledge of the group, it could be identified. It shows no sign of a crest and the hair of the head radiates straight back from the facial limit, while the face and cheeks are surrounded by long black hairs. In colour it is of a light golden buff all over, with a tendency to a black tip on the tail. |
