This monkey, while resembling somewhat P. opscura, is easily 
distinguished by having the thighs colored like the upper part of the 
body, by the absence of a conspicuously defined nuchal patch, and by 
the dark tail. The hair is much less silky in texture, and more fitted 
for the less temperate climate of the northern region in which it 
dwells. The unique type was collected by L. Tea, and presented to 
the British Museum by the Marquis Doria. :
