44 MAMMALIA. QUADRUMANA. 



He arrrived in England in August 1817, and survived his transportation till the 

 first of April J819, in the custody of Mr Cross at Exeter-Change. He was shedding 

 his teeth at the period of his death. A figure of the head of this animal, drawn 

 from a cast taken after death, is given by Mr Griffith, (An. King. i. 252), and the 

 head and hands of the adult are figured in Brewster^s Journal^ iv. pi. 4. 



Sub-gen. 2. GIBBONS, Hylobates^Ill. Callosities on thebuttocks* 



P. lar, Desm. (Simla lar, Lin.) The Gibbon. Fur black ; face 

 surrounded with gray hairs. About sixteen inches in height ; 

 arms almost reaching the ground when the animal is erect. In- 

 habits Coromandel, &c. 



P. variegatuSjDesm. (Simla lar,var. Lin.) Fur variegated with gray 

 brown and deep gray. A third smaller than the preceding. - 

 Inhabits the island of Malacca. 



P. leuciscus, Desm. (Simla leucisca, Schreb.) Fur gray ash-colour- 

 ed ; face black ; strong callosities. 

 Similar in form to the preceding, but having the arms longer. They sometimes 



walk erect, balancing themselves with their long arms upon the high branches of the 



bamboo in Java and the Moluccas. 



P. syndactylus, Desm. (Simla syndactyla, Raffles.) The Siamang. 

 Fur of a deep black,, woolly, and very thick, naked under the 

 throat ; index and middle finger of the posterior hands united to 

 the second joint. 



These animals are common in Sumatra. They are generally found assembled in 

 large troops, conducted, it is said, by a chief, whom the Malays believe to be invul- 

 nerable. Assembling at sunrise and sunset, they vie with each other in making the 

 most dreadful cries. At all other times they appear to be perfectly quiet. When 

 any of a troop is wounded it is abandoned to its fate, unless indeed it be a very young 

 one. In this case maternal affection prevails, and the mother of the bleeding young 

 will sacrifice her own life in an ineffectual attack on the enemy. Affection is al- 

 so often displayed under more pleasing circumstances in the care of the persons 

 of their young, by washing, rubbing, and drying them, in spite of the pettish cries 

 and resistance of the little Siamang. This species is readily tamed ; but, unconquer- 

 ably timid, it never displays familiarity, and its submission seems rather the result 

 of apathy than of confidence. It displays little intellectual vigour. It drinks by 

 plunging the fingers in water and then sucking them. Griffith's An. King. i. 256. 



P. agilis, Desm. (Hylobates agilis, F. Cuv.) The Active Gibbon. 



Fur brown, with the back yellow ; forehead very low ; orbital 



arches very prominent ; face of the male bluish black, that of the
