its tributaries, either solitary or in parties of about half a dozen ; 

 they were very active and wild. 



In the Botanical Gardens, Penang, I have seen this species 

 playing in the trees. On Penang Hill I have occasionally seen 

 Lutongs which appeared to belong to this species ; they are very 

 shy, and it is difficult to see much of them before they disappear 

 among the jungle trees. 



In the Museum at Taiping there are specimens from the Larut 

 Hills, Perak. In April 1898, at about 3500 feet elevation in the 

 Larut Hills, I came on a party of from 10 to 20 Semnojrithcci, of 

 this or a closely allied species. 



Eidley (J. S. B. B. A. S. 1894, no. 25, p. 57) says : " 8. obscurus, 

 Reid. The Grey Lotong. This monkey, which is common in 

 Pahang, varies much in colour. Here it is of a dark grey, while 

 further south, in Johore, it is almost black." 



Kelsall (J. S. B. R. A. S. 1894, no. 26, p. 16) says : " S. obscurus, 

 Reid. The Dusky Lotong. This species is very nearly black in 

 Johore. Several specimens were obtained. Common everywhere 

 in the inland districts." 



There are two stuffed specimens in the Siamese Museum, labelled 

 " Siam." 



Colour. Specimens from Kedah. The very handsome fur is 

 darkish grey above, paler below, with hands and feet black. The 

 face is black except for the white nose and the distinctly defined 

 white spaces or rings round the eyes. Iris brown. 



Size. Specimens from Kedah : —

 Monkey. 



Semnopithecus femoralis, Blanf. Faun. Ind., Mamm. p. 42. 



Cantor (p. 5) apparently obtained only one specimen — from 

 Purlis (a small State on the west coast of the Malay Peninsula, 

 north of Kedah), and says that the species does not appear to 

 occur in either Penang or Singapore. Ridley (Mamm. Malay Pen. 

 p. 26), however, says " it is not very common in Singapore, but a 

 few occur in most of the larger jungles." Mr. Oldfield Thomas 

 (P. Z. S. 1886, p. 72) mentions a specimen from Klang, Selangor, 

 collected by Mr. Davison. 



In September 1897, in the woods among the foothills of Gunong 

 Pulai, Johore, were many Lutongs of this species going about in 

 flocks ; they were sby and difficult to see except for a glimpse of a 

 black form disappearing from one high tree to another. 



In the Museum at Taiping there are several stuffed monkeys 

 which I feel inclined to refer to this species. Some from the 

 Larut Hills are labelled by Mr. Wray S. cristatus, Horsf. & Raffl.,
