SEMNOPITHECUS MAURUS. 
the tarsus, which is naked below, and comprises nearly one half of the length of 
the hand. The thumb is very robust, and placed near the fingers, so as to assist in 
rendering complete the movements and offices of the hands of these extremities. 
The length and stoutness of the fingers are proportionate to the stoutness of the 
thumb. The nails of the fingers are uniformly rounded, and elevated in the middle ; 
and of the thumbs, of both extremities, flat and depressed. 
The covering of the Semnopithecus maurus, in adult subjects, is intensely 
black on every part, except the breast, the abdomen, the inner side of the extremi- 
ties, and the root of the tail ; these parts are gray. On the crown of the head, the 
black hairs are slightly tipped with gray ; and as age advances, the gray portion becomes 
more extensive, and also shews itself on the upper parts of the body ; but the 
extremities exteriorly, and the tail, even in the oldest subjects, retain their blackness. 
The hairs are remarkably long, delicate, soft, and silky. On the sides of the head 
they are disposed backward, with a slight inclination outward, and they completely 
conceal the ears. They rise with a gradual slope on the forehead, but on the crown 
of the head they are suddenly deflected, so as to form a dependent crest. On the 
back and on the extremities they lie smooth and close. They are greatly elongated 
on the sides of the body, between the shoulders, so as to hang down to a considerable 
length, when the animal walks on all fours. On the breast anteriorly, and on the 
abdomen, they are short, lax, and straggling. 
The covering of the Simia maura, in its young state, exhibits a great contrast 
to that in the adult. Immediately after birth, our animal has a fulvous or reddish- 
yellow colour; as it advances in age, the colour gradually changes. A gray disco- 
louration first shews itself on the hands, the forehead, and the tip of the tail ; from 
these parts it gradually extends to the neck, the shoulders, and the flanks, and 
assumes from time to time a darker hue, until the coat of the animal is jet black 
above, and gray underneath.

The Semnopithecus maurus is distinguished among the Javanese by the name 
of Budeng, from another species, which has the same form and habit, but a
