CHARACTERS.--Face and sides of head nearly naked; top of head with large, erect, crest; hair of neck elongated; tail not ringed.

General colour greyish-brown; outside of limbs and base of tail, washed with rusty-red; crest, throat, and lower surface of body, fore-limbs and front edge of hind-limbs white; extremity of the tail black.

PLATE XIII.

{141}Differs from the preceding species, M. geoffroyi, in having a crest.

DISTRIBUTION.--The Pinché Monkey is found in the forests of New Granada, near the coast.

With the succeeding species we commence the description of the Tamarins which have no conspicuous mane on the back of the neck, and that section whose members have a patch of white hairs around the mouth, each looking at a short distance, as Mr. Bates remarks, "as though it held a ball of snow-white cotton in its teeth."

IV. THE WHITE-LIPPED TAMARIN. MIDAS LABIATUS.

Midas labiatus, Geoffr., Ann. Mus., xix., p. 121 (1812); Gray, Cat. Monkeys Brit. Mus., p. 66 (1870).

Jacchus labiatus, Desmarest, Mammalog., p. 95 (1820); Humb., Rec. d'Obs. Zool., Prod. sp. 44 (1811).

Hapale labiata, Wagner in Schreb., Säugeth., i., p. 246 (1840); Mus. Pays Bas, vii., p. 260 (1876, part).

CHARACTERS.--General colour black; under side reddish, the black terminating on the front of the chest in a straight line, the hinder part of the back washed with grey; the hinder part of the chest, belly, inside of the limbs, and the under side of the root of the tail, rust-colour; tip of nose and edges of upper and lower lips white.

DISTRIBUTION.--The forests on the north side of the Amazon.

{142}V. THE RED-BELLIED TAMARIN. MIDAS RUFIVENTER.

Midas rufiventer, Gray, Ann. and Mag. N. H., xii., p. 398 (1843); id. P. Z. S., 1865, p. 735; id. Cat. Monkeys Brit. Mus., p. 66 (1870).

Midas elegantulus, Slack, Proc. Acad. Nat. Sc. Philad., 1861, p. 463.

Hapale labiata (nec Geoffr.), Schl., Mus. Pays Bas, vii., p. 260 (part).

CHARACTERS.--Head, throat, fore-limbs, tail, and hands deep glossy black; hairs of back, sides, and posterior limbs black, broadly tipped with white, not regularly ringed; belly, breast and inner surface of limbs bright brick-red, separated by a distinct line from the black of the back and outer surface of the limbs. On the back of the head a small patch of the same colour as the back; on the top of the head a golden-yellow triangular patch. Lips and tip of the nose, white.

This species is distinguished from the White-lipped Tamarin (M. labiatus) by the spot on the crown and nape; and by the rufous of the under side extending forward nearer to the throat.

DISTRIBUTION.--Banks of the Upper Amazon. Mr. Bates shot a specimen at Tunantins in 69° W. long., and 4° S. lat.

HABITS.--Nothing is known of the habits of this species.

Closely allied to the Red-bellied Tamarin is the so-called MOUSTACHED TAMARIN (Midas mystax, Spix), in which the head, shoulders, and tail are black; the body above brown, sometimes ringed with white, and the belly bright rust-coloured. It can be distinguished, as Dr. Slack points out, from M. rufiventer, by the want of the ashy tips to the hairs of the back {143}and posterior limbs, and the triangular golden spot on the vertex. The hairs of this spot are golden throughout their entire length, in this respect resembling another closely related Upper Amazonian species, the so-called BONNETED TAMARIN (M. pileatus, Is. Geoffr.), from which it can readily be distinguished by the black colour of the under surface. The back of the Bonneted Tamarin is also varied, black and grey, the limbs and tail are blackish, and the lips white.
