WHITISH SAKI. 



Type locality. Lake Teffe, near £ga, on the Solimoens River, 

 Brazil. Type in British Museum. 



Geogr. Distr. Tonantins to Peru, on the Solimoens River, Brazil. 



Genl. Char. Size large. Hair long and loose hanging down the 

 sides to knees and elbows; tail long, bushy; hair on back of head 

 leaning forward, forming a hood as in P. monacha. 



Color. Face covered with short white hairs; head, shoulders, 

 sides of body, limbs, hands and feet whitish ; back, upper part of sides 

 and tail black, the hairs with whitish tips ; under parts russet ; hands 

 and feet whitish or grayish. Ex type in British Museum. 



Measurements. About the size of P. monacha. 



The type and paratypes of this form described by Gray are in 

 the British Museum Collection, and seem entitled to be regarded as 

 distinct. They differ in color from all other Pitheciae. The adult 

 does not agree with Gray's description for the shoulders and arms 

 are not black, but whitish, the black of the back only covering the back 

 between the shoulders, and there is no black whatever on the arms. 

 The 'whitish' of Gray's description has now become a pale, dirty, 

 yellowish brown, probably giving a very incorrect idea of the animal s 

 appearance in life. The hairs on hands and feet are quite short, the long 

 hairs not going beyond the wrists and ankles. The long hair of the 

 head comes forward to the face as in P. monacha, but the texture is 

 quite different from the hair of that species, being not harsh and 

 straight but having an inclination to curl. 



Bates, to whose book I have so often referred, says, (1. c.) that 

 this monkey is found on the banks of the Teffe south of the Solimoens. 

 An individual, since placed in the British Museum, was a pet of a 

 young Frenchman at £ga. It was so tame that it followed him like 

 a dog about the streets. Its owner was a tailor, and the monkey passed 

 most of the day on his shoulder while he was at work. It was not 

 friendly, however, to any other person.
