below it, passing upwards and forwards across the outside of the limb, 

 on tbe front aspect of which it bends inwards and slightly downwards 

 to the chest. The fold before the haunch, between the groin and 

 the back, is short and less strongly marked than the shoulder-fold ; and 

 its upper extremity is on a level with the head of the femur, it's di- 

 rection being downwards and somewhat forwards. The two folds on 

 the back of the haunch are very short, and the internal extremity of 

 the upper one is on a level witli the lower margin of the genital ori- 

 fice ; the fold below them, across the leg, passes forwards and down- 

 wards, and is the most indistinctly marked of all the folds, almost 

 disappearing when the limb is stretched backwards. The more or 

 less pendulous fold of the neck arises from behind and below the level 

 of the ear, and is continuous below with its fellow of the opposite side ; 

 the skin behind this fold is loose, and forms another fold, which dis- 

 appears, however, when the neck is raised. 



The tubercles of the skin are so small and flat that the skin is 

 almost smooth ; they are about the eighth of an inch in diameter ; 

 and each is surrounded by a shallow sulcus, in which usually four 

 bristles are placed. The latter structures are erect and about one 

 inch in length, and are rather richly distributed, being especially nu- 

 merous on the lower parts of the sides, on the front of the metacarpal 

 and on the back of the metatarsal joints, and less so on the cheeks, 

 throat, and sides of the lower jaw ; while, anterior to the eyes, the 

 face appears to be nude, except on the anterior surface of the pendu- 

 lous upper lip, which has strong bristles set widely apart. On the 

 upper half of the trunk the bristles posterior to the shoulder-fold are 

 almost white in some lights, with a rufous tint in others, while those 

 anterior to the shoulder-fold are dark brown ; on the lower half of 

 the trunk and on the limbs they are black, and on the sides of the 

 belly and over the wrist and heel they are depressed and somewhat 

 curly ; on the neck and head they are shorter and almost white, 

 The hairs on the two margins of the lower third of the tail increase 

 in length from above downwards, the apical hairs being about six 

 inches in length, black at the base, and dark brown throughout the 

 rest of their extent ; the upper two thirds of the tail are covered 

 with light-coloured bristles. 



The general colour of the dry skin is ashy grey ; but when moist it 

 becomes a light brown. The axillae and under surface of the groin, 

 and the creases formed by the folds of the body and neck when these 

 are extended, have a fleshy tint. 



The animal is remarkably quiet, considering that she is chained by 

 her four feet between two trees. During night she becomes very rest- 

 less, and on several occasions has contrived, by stretching her hind 

 legs to the utmost, to reach a strongly built brick wall, which she 

 has butted down with her head. Her restlessness rather increases 

 with the dawn, which is the time when tropical animals that are not 

 exclusively nocturnal in their habits are most active in their move- 

 ments and in their search after food. After the sun is fairly up and 

 she has been satiated by a hearty meal, she lies down on her side, and 

 sleeps until the blazing sun has. half run his. course between the' me-
