Nyctipithecus rufipes, Sclater, P. Z. S., 1872, p. 3, pi. i. 

 Nyctipithecus vociferans, Spix, Sim. et Vespert. Bras., p. 25,

(Plate XV.} 



Characters. Above grey, slightly washed on the back with 

 rufous ; under side reddish fulvous ; three vertical black stripes 

 on the head, similar to N. trivirgatus, but much less distinct, 

 narrower, and showing a prominent triangular white patch over 

 each eye ; ears large and prominent, almost nude (perhaps the 

 result of captivity). Hands and feet rufous ; tail short-haired, 

 cylindrical ; the basal half rufous, the remainder reddish- 

 black. Length of the body, u inches; and of the tail, 16 

 inches. The absence of the long chestnut patch on the back 

 distinguishes N. rufipes from N. trivirgatus, and its paler colour 

 and the indistinctness of its head-stripes, separate it from TV! 

 felinus. 



Distribution. Nicaragua; San Juan del Norte.
