long and dog-like ; the body is short, compact, and broad-chested, with moderately 

 long, powerful limbs. The head is somewhat flattened above, with pronounced 

 supraorbital ridges. The limbs are relatively longer than in 31. leoninus. The tail 

 is a little more than one-third the length of the body and head, and is rather sparsely 

 clad, contracting somewhat rapidly to a point and carried erect, being somewhat 

 downwardly curved near the tip. 



There are not the marked differences that distinguish the sexes of M. leoninus, 

 Blyth, to which this form is most closely allied, the males and females being alike, 

 and the young are only a little more richly coloured than the adults. These latter 

 attain to a great size, as is evinced by the dimensions of the cranium of the adult 

 (see table, p. 55). I have seen specimens standing at the shoulder as high as a good- 

 sized mastiff and quite as powerful. 



The chief feature of the skull is the great development of the facial portion, 

 which is thrown much forwards. 



It inhabits the Malayan peninsula to tlie south of Tenasserim, Sumatra, and 

 Borneo.

Eace red ; tail short and stumpy, well clad and tufted. General colour, dark 

 yellowish brown. 



The face is nude, with the exception of a few straggling hairs on the upper lip 

 and back part of the cheeks, and a moderately long, yellowish-brown beard. Tlie . 

 colour of the face is intense red with a purplish hue ; but the area of the nose and 

 the lower lip is more or less tinged with brown. The colour of the face is most 

 intense during the rutting season. The callosities and the genitalia of the male are 

 also more or less red. The ears are large and covered entirely with lone silky haks 

 which, however, disappear on their margins. The sparse silky hairs which surround 

 the face are black or dark brown. The fur of the upper parts is darkest on the dorsal 

 line, and of a yellowish brown, as the hairs are annulated with these two colours. 

 The sides of the head, the breast, the under surface of the limbs and tail, and the 

 belly, are greyish. In the adult and old individuals the hair is long, soft, silky, and 



1 In 1838, Ogilby, in his anonymous "Treatise on the Natural History of Monkey.s, Lemurs, and Opossums" 

 published in the " Library of Entertaining Knowledge" (Charles Knight, "Menageries," 1838), recognised that the 

 Japan monkey was distinct from the M. speciosns, Y. Cuvier {= M. arcioides), and proposed for it the n'ame of Papio 

 japonicus ; and he mentions that he had observed a living example of true M. speciosus.
