HABITS.--These Monkeys live in small companies composed of both sexes, in the highest trees in dry spots of the forest, never descending of their own accord to the ground, nor {120}visiting the rice-fields, as their food appears to consist exclusively of fruits. They may be met with, according to Mr. Iversen, the discoverer of this species, at all seasons of the year in the same parts of the forest. They hardly ever visit the more open places, but keep to the highest tree-tops, and make most astonishing leaps from one branch to another. Those observed were very shy, and, on being perceived, would seek to hide in the leafy tops of the trees, even leaving their young exposed on the lower branches. The mother carries her young one under her belly. The species was often observed in company with the Siamang (_Hylobates syndactylus_), but not with other Monkeys. XII. EVERETT'S LANGUR. SEMNOPITHECUS EVERETTI. _Semnopithecus everetti_, Thomas, P. Z. S., 1892, p. 582, pl. xli.; Hose, Mamm. Born., p. 15 (1893). (_Plate XXXVI._) CHARACTERS.--Very closely allied and very similar to _S. hosii_ in size and coloration, but the white is everywhere replaced by dull cream-colour, giving a yellowish wash to the mixed grey of the back and tail; shoulders and middle of back darker; under surface of body and light parts of head cream-colour, instead of white; whole of the forehead and top of the head black, the lower limit of the black passing across the middle of the ear; entire back of neck black; spot in the centre of the forehead above where the eyebrows meet, yellowish-white. The colour of the face, cheeks, and sides of the neck, in contrast to the dark crown, distinguish this species from _S. chrysomelas_. Length of body, 21¾ inches; of tail, 25¾ inches. (_Thomas._) "Since Mr. Thomas described this Monkey," writes Mr. C. Hose in his "Mammals of Borneo," "I have obtained several other specimens, ... and the marking is quite constant." PLATE XXXVI. [Illustration: EVERETT'S LANGUR.] {121}DISTRIBUTION.--Borneo: Mount Kina Balu. Mount Dulit and Mount Batu Song in Sarawak, ranging from 3,000 to 3,500 feet above the sea. HABITS.--This species is a purely mountain form, and does not descend to the plains. XIII. THE CROSS-BEARING LANGUR. SEMNOPITHECUS CRUCIGER. _Semnopithecus cruciger_, Thomas, Ann. N. H.
