_Galago monteiri_, Bartlett, P. Z. S., 1863, p. 231, pl. xxviii.
_Callotus monteiri_, Gray, P. Z. S., 1863, p. 145.
CHARACTERS.--Fur Mouse-grey at base, with white tips; pupils of eyes oval
and vertical; ears very large and naked; hairs on face and cheeks short;
feet broad, short, and strong; toes {47}broad, with rounded discs; thumb
very broad; tail very long. Entirely pale grey over the head, face, cheeks,
body, and tail; throat nearly white; hands and feet dark brown, nearly
black; nose black; ears nearly black. One of the largest species of the
Sub-family. Length, 12 inches; tail, 16 inches long.
DISTRIBUTION.--This species was discovered by Mr. Monteiro in Cuio Bay on
the West Coast of Africa, to the south of Loanda; and the late Captain
Cameron, R.N., brought a few specimens home with him from Bailunda, on his
return from his celebrated march across the Continent.
HABITS.--Little is known of this species from observation in the field. A
few specimens have reached Europe, and on one that lived in the Zoological
Gardens in London, Mr. Bartlett made the following observation: "The animal
has the power of turning its ears back by the complex muscles of their
external aspect, and folding them up when at rest. When moving about or in
search of food they spread out and stand upward and forward, reminding one
of those of the Aye-Aye; but when folded back and down, the animal's face
bears a strong resemblance to the Douroucouli (_Nyctipithecus_)."
