{Plate XVIL) 



Characters. — Above grey, slightly washed on the back with 

 rufous ; under side reddish fulvous ; three vertical black stripes 

 on the head, similar to N. trtvirgatus, 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, 11 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 N. 

 felinus. 



Distribution. — Nicaragua ; San Juan del Norte.
