THE MARIKIXA, SAGOUIN, AND TAMARIN. 99 



banks of the Solimoen river, in Brazil ; Bates saw it near San Pablo, iind 

 remarks that on his return to England he was surprised to see a specimen 

 in the British Museum, described as coming from Mexico. The scientific 

 name of this specimen is Hapale PVGMiEA. 



II.— GENUS MIDAS. 



The members of this genus are distinguished from the genus Hapale 

 by the circumstance that the mane is less developed, and that the tail is 

 longer. The number of species is twenty-four. 



The Marikina, Midas rosalia, is larger than the animals just de- 

 scribed ; the face is bare and brown ; the ear large and fringed with dark- 

 brown hair ; on the cheeks and on the pointed brow fine, short, yellowish 

 hair stands out ; the long hair of the head, divided in the middle by a 

 streak of short brown hair, falls down like a mane, and has a dark-brown 

 color, while the rest of the head, the throat, the breast, and the arms are 

 dark orange-brown ; the remainder of the body is covered with a reddish- 

 yellow fur which glistens like gold. This fur is smooth and silky to the 

 touch, and the creature is hence sometimes designated as the " SiLKY 

 Monkey." It is very fastidious about having its beautiful coat kept 

 carefully clean, and soon dies if neglected. It is very timid, has a soft 

 and gentle voice when pleased, but hisses when angry. It is described 

 by Buffon under the name of " Marikina." 



The Silver Sagouin, Midas argcntatiis, is one of the rarest of the 

 American apes, and, according to Bates, is found only in Cameta, a 

 province of Brazil. It is the most beautiful of all ; the long silk}' hair 

 is silver-white, the tail dull-black, the almost bare face flesh-colored. It 

 reaches the length of only eighteen inches, including ten inches of tail. 

 Many naturalists regard it merely as a variety of the common Midas. 



The Tamarin, Midas ursultis, has a pleasing expression, and a face 

 of considerable intelligence. It is black, but the hinder part is mottled 

 with grayish-white. Bates says it never congregates into large flocks, 

 seldom more than three or four being seen together. Like the squirrel 

 it confines itself to the large boughs of trees, whence it peers down on 

 the traveler. It seems, however, to have no fear of man. 



The Marmosets do not seem to be possessed of a very large share of 

 intelligence, but yet are engaging little creatures if kindly treated.
