436 QUADRUMANA. 



The preceding views have been recently confirmed by Dr. Miiller, who 

 notices a variation in the colouring of the H. longimanus (H. Lar), similar 

 to that which prevails in the Ungka'puti, or H. agilis. " The proper Lar 

 or Great Gibbon of Buffon," he states, " has been described by Messrs. 

 Vigors and Horsefield, under a new name that of S. albimana. This 

 species is only observed on the Continent of India, in the neighbourhood 

 of Malacca and Siam, where it appears to be common. It is rather larger 

 than the Oengko of Sumatra, and is distinguished by a more slender 

 figure, and by longer arms. Of this species, also, individuals are found, 

 both of a dark and of a paler hue ; but those of the darker colour seem to 

 be most common. Generally, the yellowish-white individuals, less abundant 

 than the dark, prove to be females of this species (the true S. longimana, 

 Schreber). The adult male is commonly of a dark brownish black colour, 

 with the exception of a circle round the face ; and of the hands, which are 

 of a pale yellow-ochre tint. Generally, the aged female is coloured in the 

 same manner ; but the tint of the body is a little paler, and approaches a 

 yellowish brown." 



GENERAL HISTORY. Of the habits and manners of the white-handed 

 Gibbon, or Lar, no details have been received : it may, however, be safely 

 presumed, that they resemble those of the agile Gibbon, and other species.

LOCALITY. Java. 



DESCRIPTION. The fur is fine, long, close, and woolly. The general 

 colour is ashy grey, sometimes slightly tinged with brown, paler on the 

 lower part of the back ; the top of the head, and the backs of the hands 



of the head, where it was nearly black, and whence it extended, a little paler, over the shoulders and 

 upper part of the back, thence gradually fading to pale brown on the haunches and rump ; the legs and 

 arms were pale brown; the abdomen was brownish grey; a white frontal band, extended over the 

 whiskers, at the sides of the face, and over the beard beneath the chin, but with a tinge of yellow; the 

 hands, including the wrist and the feet, were yellowish white ; the short hairs on the face were dirty 

 white ; under the chin the beard was full, but at the sides of the face rather shorter ; the chin itself 

 was only scantily clad with hair ; the long superciliary hairs were black ; the fur was generally paler at 

 the base. On the top of the head the fur was rather short, wavy, or wool-like, and directed backward 

 from the forehead. The index and second toe, but partially united, at the base of the first phalanx.
