466 EXPLANATORY INDEX. 



REDSTART (Setophaga or Muscicapa ruticilla). It has 

 nothing to do with the English Redstart. 



RHINOCEROS BEETLE (Megasoma Titan), popularly called the 

 Great Brown Sawyer. 



Roucou. See " Paint." 



SACAWINKI. One of the Squirrel Monkeys. 



This tiny monkey, several times mentioned by Waterton, 

 is plentiful in Guiana, and is noticed by Schomburgk. 



" A troop of little Sacowinkis, or squirrel monkeys, some 

 of the most beautiful and active of their kind, leaped with 

 the agility of a tame squirrel from branch to branch, and, 



SACA.WINKI. 



alarmed by our appearance, uttered their painful call, re- 

 sembling much more the cry of a bird than that of an animal, 

 and then, hastening away, were soon hidden among the thick 

 foliage of the large forest trees." 



Several species of squirrel -monkey appear to be included in 

 the general name of Sakawinki. Stedman figures the Marmoset 

 (Jacchus vulgar is) under the name of Sakawinki, while 

 Waterton, who mentions it as being black, and scarcely six 

 inches in length, evidently refers to the White- whiskered 

 Tamarin (Jacchus leucogenys), which exactly accords with his 

 description and has accordingly been figured.
