Characters.—Above grey, slightly washed on the back with 
rufous ; under side reddish fulvous ; three vertical black stripes 
on thhead, similar to LV. ¢vivirgatus, 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 JV. rufipes from JV. ¢rivirgatus, and its paler colour 
and the indistinctness of its head-stripes, separate it from JZ. 
Selinus. 
Distribution.— Nicaragua ; San Juan del Norte.
