OTHER SPECIES 



In Eastern Peru the place of the red-faced spider-monkey is 



taken by a closely allied species (A. ater), in which the face is of the 

 Spider-Monkey 



same black tinge as the fur. From this feature the species derives its 



distinctive title of the black-faced spider-monkey. According to Dr. Gray, it 

 is further distinguished from the red-faced species by the shorter hair on the 

 forehead. 



Passing by one or two species, such as the grizzled spider-monkey 



00 e r " (A. grisescens}, we come to a very well-marked form, known 



as the hooded, or black-capped spider-monkey {A. cucullatus) , first 



described by Dr. Gray from a single example living in the London Zoological 



Society's Gardens, of which the exact habitat was unknown, although believed to 



be Colombia. 



This species is distinguished by the length of the flaccid hair, which is of a 

 mixture of black and silvery gray in color ; and on the crown of the head is 

 elongated, so as to form a large hood, or penthouse over the eyebrows. The fur of 

 the hands, the feet, the crown of the head, and the nape of the neck, is deep black ; 

 while the naked parts of the face are flesh colored. 



The chuva, or white- whiskered spider-monkey (A. marginatus) , 

 White- Whisk- jj as a i rea dy been incidentally mentioned as found in the Lower 



Amazon valley, to the southward of the river plains which are 

 Monkey 



inhabited by the red-faced species. 



It is of nearly the same size as the red-faced spider-monkey ; but .has mod- 

 erately long hair, of a uniform black color, with the exception of that on the 

 forehead and the whiskers, which is white ; the face being flesh colored. As in 

 the last species, all trace of the thumbs has disappeared. It does not appear to be 

 common, since Mr. Bates seems only to have come across one pair, both of which 

 were shot, while specially searching for it in the valley of the Tapajos river. 

 Being at the time unable to procure other animal food, this enterprising traveler 

 was fain to try the flesh, and describes it as being the best-flavored meat he had 

 ever tasted, although it was with difficulty that he persuaded himself to make the 

 attempt. 



This species (A. hybridus) is a native of Colombia, and is of an 



' r M ^ 1 , pl e: " ashy-gray color, sprinkled with black over the greater part of the 



body ; the fur being very soft, with a tendency to curl, and mixed 



with a certain number of long and stiff blackish hairs. Other parts, however, such 



as the crown of the head, the fore-arms, the thighs, and the greater part of the tail, 



are black ; the face being blackish, with white hairs on the lip. The inside of the 



thigh and upper arms are grayish. This monkey is but little known in Europe.

hands, feet, and the crown of the head being of a full black, while the fur of the
