A fine male specimen, in the museum of the Zoological Society, Lon- 

 don, measures two feet ten inches in total length ; the length of the arm 

 and hand is two feet five inches. 



In a beautiful adult female specimen of H. agilis, examined January 

 7th, 1839, at the museum of the Zoological Society, the toes were not 

 at all united. The fur of this specimen was glossy, and of a silky tex- 

 ture ; its colour was pale golden yellow, like raw silk, deeper at the roots ; 

 a straw-white superciliary stripe passed across the forehead ; the chest, 

 abdomen, inside of the humerus and of the thighs, were pale umber 

 brown ; the back of the thighs was of a deep golden hue ; length, from 

 vertex to heel, two feet five inches. 



In the Museum of Paris is a specimen of a female Gibbon, which 

 appears to be of the variety Ungka-puti. Above the eyebrows, which 

 are long and black, are perceptible indications of a pale superciliary line, 

 and the full hair round the face is decidedly paler than that of the 

 body ; the general colour, straw-white, with a dusky brownish hue, the 

 straw-white being purer on the back, especially at its lower part ; on 

 the throat and chest the hairs are washed with brown ; the face is black, 

 with scattered black hairs ; head and body, seventeen inches and a half ; 

 hind limbs, to heel, thirteen inches ; arms and hands, twenty-four inches. 

 According to Sir T. S. Raffles (Linn. Trans, xiii. p. 243), the 

 Ungka-puti is from two to three feet in height, of a slender and delicate 

 figure ; covered with soft hair, somewhat woolly, and of a dull yellowish 

 white, darkening to brown on the under and inner surfaces ; the shades, 

 however, varying much in different individuals ; * the face and hands, 

 naked and black. Messrs. Diard and Duvaucel state the face of the male 

 to be bluish black ; that of the female, to have a slight tint of brown. 



VARIETY : UNGKA-ETAM. The following is the description of an 

 adult male specimen in the Paris Museum (de Sumatra, par M. Duvaucel, 

 1821): 



The fur is deep, soft, close, and woolly ; the general colour is black, 



tinged with brown, passing into a chocolate -brown on the loins (in 



another specimen, the loins and lower part of the back are still paler) ; 



the hands and feet are black ; a superciliary band, and the whiskers, 



which are full and bushy, are white ; the eyebrows consist of black, stiff 



hairs ; the total length, from the head to the heel, is about two feet nine 



inches ; the length of the arm and hand is nearly twenty-four inches. 



In another male specimen, the beard is grey, with a flaxen tint. 



A female specimen, in the same museum, presents the following 



characters : the general colour is brownish black, the brown prevailing 



" The uncertain colouring of this Ape, and the want of precise terms of expression for the 

 various tints, prevent the possibility of giving a precise idea of it to those who have not seen the 

 animal." Fred. Cuv. Mamm.
