98 QUADRUMANA. 



The Leoncito Marmoset, Hapalc Iconina, was discovered by the 

 great traveler Humboldt on the warm plains which border the eastern 

 slopes of the Cordilleras. He says : " It is one of the most beautiful 

 creatures I ever saw — lively, merry, and playful, but like all little animals 

 passionate and spiteful. When angry the neck swells, the mane bristles 

 up and it looks like a lion in miniature." Bates saw a very tame one on 

 the upper Amazon and relates: "It ran to my chair, climbed up to mv 

 shoulder, turned about to look into my face, showing its little teeth, and 

 squeaking as if asking my will." This species attains a length of eight 

 inches in the body, and about the same in the tail. 



The next species differs from the others by having tufts of hair more 

 or less developed before and above the ears. 



The Marmoset, Ouistiti, or Sagouin, Hapalc lacchus (Plate III), 

 the commonest member of this group, has a body nine to ten inches long, 

 and a tail twelve to fourteen inches. The color of its long silky fur is 

 black, white, and reddish-yellow. The tail is black, with about twenty 

 small white rings around it and a white tip. 



The PiNCllE, Hapalc CEdipus, has long hair on the top of its head, 

 which hangs down over the forehead and neck, but the sides are bare. 

 Specimens have been found to measure twenty-eight inches, including 

 sixteen inches of tail. 



The Pinche is remarkable for the tuft of white and long hair which it 

 bears on its head, and which is so distinctly marked that the little creature 

 almost seems to be wearing an artificial head of hair. The throat, chest, 

 abdomen, and arms, are also white, and the edges of the thighs are 

 touched with the same tint. On each shoulder there is a patch of 

 reddish-chestnut, fading imperceptibly into the white fur of the chest, 

 and the grayish-brown hair that covers the remainder of the bod)^ Its 

 eyes are quite black. 



The tail of the animal is long and moderately full ; its color slightly 

 changes from chestnut-brown to brownish-black. Its voice is like the 

 twittering of birds. Unfortunately this pretty creature cannot endure 

 captivity, and soon dies. 



To the same group belongs the smallest of all the apes, a little crea- 

 ture which measures at the utmost only twelve inches, including fully 

 six inches of tail. Its fur is yellow and black, its paws reddish-3-ellow. 

 Dark bands run from the back over the sides and thighs. The tail has 

 slight rings. Spix discovered this dwarf species at Tabatinga, on the
