LION TAMARIN. 



Type locality. Seen at Popayan, Brazil. No specimen preserved. 



Color. General hue ochre yellow shading into olive brown, annu- 

 lated with black ; back varied with yellow ; hands and feet black, face 

 black ; around the nose and mouth bluish white. 



Measurements. Total length 7 to 8 inches. 



No specimens of this monkey have been procured. Humboldt saw 

 two living individuals at Popayan and from these he made his descrip- 

 tion and gave the name of leonina (1. c). It inhabits the plains of 

 Mocoa, and the fertile banks of the Iga and Japura rivers, never goes 

 into temperate regions, and is rare even in the country it inhabits. 



Whether these specimens represent a distinct species, or some 

 state of pelage of L. rosalia, or a dark form of that species it is 

 impossible to state, and any decision regarding it will have to be 

 deferred until examples are procured.
