"About the jungles of Nychow (S. Hainan) these Monkeys," says Mr. Swinhoe, "were very common. On our landing, abreast of the ship we saw a large party of them on the beach, but they at once retired into a grove above high-water mark. We watched them running along the boughs of the trees and {25}jumping from branch to branch. The discharge of a fowling-piece soon made them scurry away into the thicket, but every now and again their heads would appear from the higher bushes, watching the movements of the enemy. At last, when they observed that our presence implied actual danger to themselves, they climbed the hills and posted themselves about conspicuous rocks, where they chattered and grunted out of danger. Their cries are very like those of _Macacus cyclopis_ of Formosa." The young clings to its mother's stomach for about a fortnight after birth, and is nursed with the greatest care by her; after that time it is able to move about by itself, and it thenceforward rapidly acquires the full use of its powers. Mr. Darwin records that the face of the _M. rhesus_, when much enraged, grows red. When watching this species in the Zoological Gardens, he says: "Another Monkey attacked a Rhesus, and I saw its face redden as plainly as that of a Man in a violent passion. In the course of a few minutes, after the battle, the face of this Monkey recovered its natural tint. At the same time that the face reddened, the naked posterior part of the body, which is always red, seemed to grow still redder, but I cannot positively assert that this was the case." XI.

Yun-nan, p. 83 (1878; with synonymy). _Macacus rhesus_, Sclater, P. Z. S., 1871, p. 222. _Macacus erythræus_ (nec Cuv.), Schl., Mus. Pays-Bas, vii., p. 112 (1876). CHARACTERS.--Very nearly allied to _Macacus rhesus_, from which it differs in its larger size, more hairy ears, and more richly {26}coloured fur, the hairs having the yellow rings rich orange or brick-red, especially on the hind quarters.

MALE.--Dark rich olive-yellow; face pale flesh-colour; sides of the face, neck, and front part of the body olive-grey; hinder parts of the body brick-red; the slaty colour of the fore-limbs, and of the anterior aspect of the legs becoming black on the hands and feet; ears flesh-colour; callosities crimson; throat, chest, and inside of the fore-limbs greyish, washed with rufous above the wrists; belly and inside of the hind limbs greyish, washed with orange-red.
