MACACUS. 65 



The hair generally is wavy, and on the shoulders and between them above and on 

 the sides of the chest it is much longer than on the hind part of the body, with the 

 exception of the dark hairs on the lower part of the flanks, which are also rather 

 long. The hair on the vertex radiates from a point about one inch above the 

 level of the supraorbital ridge, and a few of the front hairs are directed forwards, 

 but the mass outwards and slightly backwards, which is also the direction of the 

 hairs external to the radiating point. There are a few long black supraciliary 

 hairs, also others on the upper lip and chin. The callosities are closely surrounded 

 by the fur. The length of the animal along the curve of the head and back is 

 26'75 inches, the tail measuring 9J inches. 



I obtained on the right bank of the Irawady, about twenty to twenty-five miles 

 below Bhamo, a female monkey which closely agrees with the type of 31. assamensis, — 

 so much so that it is impossible to resist the conclusion that they are one and the 

 same race. It was one of a large colony living below the huge Deva-faced, limestone 

 cliff, at the foot of which lies the small pagoda of Sessoungan. The crews of passing 

 boats and pious visitors generally throw rice and fruits to these monkeys as a work 

 of merit. I observed another and similar colony some miles further down the river 

 on the same bank. At the time, I noted that the adults are apparently larger 

 and more powerful than M. rhesus. They have moderately long tails ; their bodies 

 are dark brown above, the under parts palish, but contrasting decidedly with the 

 former colour. 



The solitary specimen I succeeded in obtaining at that colony was a gravid 

 female, of which the following is a description. 



This monkey is uniformly brown, with a rufous golden tinge over the shoulders 

 and neck, the latter tint paling on the head, more especially over the external 

 angle of the forehead. It is pale yellowish behind the ears and on the back 

 part of the cheeks, where there are a few intermixed black hairs. There are 

 a few black supraorbital hairs, and the ears are tufted with hairs of similar 

 colour besides being well clad internally. The face is surrounded, from behind 

 the ears to the chin, by long pale yellowish hairs, and the beard is well de- 

 veloped, the hairs having a well-defined, almost black, suhapical band. The limbs 

 externally and the upper surfaces of the feet are concolorous with the hinder 

 quarters of the animal. The under surface of the body and limbs are of a pale 

 yellowish. The tail is dark brown at the base, paling somewhat towards the 

 tip, which is slightly tufted. The face and ears are dusky. The buttocks are 

 densely clad with hair to the sides of the callosities, but below the vulva there is a 

 small bare area which in life is suffused with dark purple. This, however, is a 

 gravid female, and I do not know what may be the characters of this region in the 

 female in heat. 



The hair on the vertex radiates more or less ; on the forehead it is erect and 

 rather short and dense, tending to divide outwards and forwards, and on the 

 shoulders it is longer than on the hind part of the body.
