Characters.—Head black; back black, washed with grey ; 
back of head, nape of neck, shoulders and humeral region 
black, washed with reddish-brown ; under side and the outer 
and inner surface of both limbs red; tail at base and tip red, 
intermediate portion black. 
The sexes hardly differ; the male being merely rather 
larger and darker, especially on the head and nape, where the 
hair is longer. 
Distribution—Mr. E. Bartlett says that this was the only 
Midas met with by him in Eastern Peru. It was plentiful 
everywhere in the Peruvian Amazons ; and he obtained speci- 
mens both on the Huallaga and Ucayali rivers. 
Habits.—This species is extremely delicate, and will not bear 
the least cold. ‘I have had them alive,” writes Mr. Edward 
Bartlett, “for two or three weeks; but they appear to suffer 
from cold and die. They are kept, however, by the Indian 
women, who make pets of them and put them into the long 
hair on their heads. With this protection they are able to live 
foralong time. Having become tame, they frequently hop out 
and feed, or, having captured a spider or two, scamper back 
again, and hide under the luxuriant crop of their owners, who 
are generally unwilling to part with them.” 

With the succeeding species commences the group of 
Tamarins with no mane and without white lips.
