[NO. 9. SEMNOPITHECUS vel PRESBYTES PILEATUS.]
The Capped Langur.
HABITAT.—Assam, Chittagong, Tipperah.
DESCRIPTION.—General colour dark ashy grey, with a slight ferruginous tint; darker near head and on shoulders; underneath and on the inside of the limbs pale yellowish, with a darker shade of orange or golden yellow on the breast and belly. The crown of the head is densely covered with bristly hairs, regularly disposed and somewhat elongated on the vertex so as to resemble a cap, whence the name. Along the forehead is a superciliary crest of long black bristles, directed outwardly; whiskers full and down to the chin: behind the ears is a small tuft of white hairs; the tail is long, one third longer than the body, darker near the end, and tufted; fingers and toes black.
SIZE.—A little smaller than P. entellus.
This monkey is found in Northern Assam, Tipperah and southwards to Tenasserim; in Blyth's 'Catalogue of the Mammals of Burmah' it is mentioned as P. chrysogaster (Semnopithecus potenziani of Bonaparte and Peters). He writes of it: "Females and young have the lower parts white, or but faintly tinted with ferruginous, and the rest of the coat is of a pure grey; the face black, and there is no crest, but the hairs of the crown are so disposed as to appear like a small flat cap laid upon the top of the head. The old males seem always to be of a deep rust-colour on the cheeks, lower parts, and more or less on the outer side of the limbs; while in old females this rust colour is diluted or little more than indicated."
Dr. Anderson says that a young one he had was of a mild disposition, which however is not the character of the adult animal, which is uncertain, and the males when irritated are fierce, and determined in attack. No rule, however, is without its exception, for one adult male, possessed by Blyth, is reported as having been an exceeding gentle animal.

The Tipperah Langur.
HABITAT.—Tipperah, Tenasserim.
DESCRIPTION.—No vertical crest of hair on the head, nor is the occipital hair directed downwards, as in the next species. Shoulders and outside of arm silvered; tail slightly paler than body, "which is of a blackish fuliginous hue."
More information is required about this monkey, which was named by Blyth after its donor to the Asiatic Society, the Rev. J. Barbe. Blyth considered it as distinct from P. Phayrei and P. obscurus, which last is from Malacca.
