Sp. Cu.—Tail vertebre rather more than half the length of body ; the terminal hairs one-fifth to one-sixth this length. Head 
above, dark brown, nearly black, with three white marks, one between the eyes, and another in advance of each ear. Above, 
chestnut brown ; beneath, yellowish white. Tail tipped with black.

rather more than half the length of the body. The ears are moderately long and high, coated 
with hair on both sides; more or less naked within the meatus. The posterior edge of the ear

the gum, of which the anterior two are convex anteriorly ; the next three bow-shaped, or in a 
double curve ; all five continuous across the palate, except, perhaps, the last one; the posterior 
two are likewise convex anteriorly, but interrupted in the centre. There is also a pair of
