212 PITHECUS 



described as brown, washed over the outer side of the fore-limbs, and 

 more especially between the shoulders and back of the neck with 

 yellowish, which appears in certain lights as pale golden, passing on the 

 upper surface of the head into a pale yellowish brown. The general 

 brownish tint is darkest on the flanks, where it has a fuliginous tinge, 

 and down the front margin of the fore-limbs, over the outer surface 

 of the thighs, the dorsi of the feet and on the tail. The inside of 

 the limbs and the under surface generally are much paler than the 

 upper parts, and have a yellowish tint, inclining to gray. Behind the 

 angle of the mouth, and below and behind the ears and on the chin, 

 the hair is rather long and nearly of the same colour as the under sur- 

 face, but slightly tipped with blackish. There is a moderately dense 

 line of rather long super-orbital hairs with a pencil of similar hairs 

 extending backwards from the external orbital angle of the frontals. 

 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 of about one inch above the level of the super- 

 orbital 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 to the radiating point. There are a few long, black super- 

 ciliary hairs, also others on the upper lip and skin. 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 9j4 

 inches." 



The type of Macacus problcmaticus Gray, in the British Museum 

 is a moderately sized brown monkey without any special character- 

 istics to distinguish it from many others. It is of one uniform tint 

 over the whole exterior portion of the body and limbs, hands and feet, 

 a sepia color becoming yellowish gray on the under parts and inner 

 side of limbs, tail brown, paler than body, some stifif black hairs on 

 the forehead over the eyes. The type was purchased from the 

 Zoological Society, was an immature individual and had lived most 

 of its life in captivity. It is practically impossible to refer this type 

 with certainty to any recognized species, and there is little to be said in 

 defense of a habit of describing individuals from Zoological Gardens, 

 that are immature, have passed most of their lives in captivity, and 

 in the majority of cases with no ascertained locality. The best thing 

 to do with all such specimens is to declare them undeterminable, and 

 strike them out of our list. Such specimens as this type of M.
