DISTRTCUTION^ OF OPHIDIANS. 231 



otlicr points of tlie peninsula beyond the Ganges, belong to 

 a species known under the name of Hylobates albimaniis, 

 which is the great Gibbon of Buffon, or the true Lar of 

 Gmeijn, Of the two Semnopitheci common in the Isle 

 of Java, one, the Semn. mitratus, is peculiar to that 

 island ; but there is found in Siam a monkey entirely 

 analogous, though with darker tints ; the other, the Semn. 

 maurus, has never been observed in any other part of the 

 globe ; but this species is evidently replaced in Sumatra 

 and Borneo by the Semn. cristatus or pruinosus, which 

 appears not to differ from the Maurus but by its fur being 

 mingled with grey. A third species is said to exist in the 

 eastern part of Java, but we have not yet received from 

 that island the Semn. auratus* or pyrrhus, which ap- 

 pears to belong to a species that inhabits the Isle of Borneo. 

 Java is far less rich in squirrels than the other isles of the 

 Straits ; we there find the Sciurus bicolor, S. nigro- 

 vittatus, S. insignis, and S. melanotis, but none of these 

 species are peculiar to that island. The Tupajas do not 

 there attain the great size of those of Borneo and Suma- 

 tra. The Boyal Tiger, which does not seem to inhabit 

 Borneo, nor any other isle of Malayasia, with the excep- 

 tion of Sumatra, here forms, as in the latter island, a local 

 variety, with very short hair ; and this variety forms the 

 extreme opposite to the Tiger of the North of Asia, to 

 which the long fur gives a very different appearance, f The 

 Island of Java breeds a fine Boar of very large size, Sus 

 verrucosus, differing much from another species, Sus 

 vittatus, which inhabits equally Java, and almost all other 

 parts of Malayasia. One of the most remarkable quadru- 

 peds of Java is the Wild BufRilo, the Banting of the na- 



* The 3'ellowisli livery of this monkej'^ is evidently periodic, or per- 

 haps due to sexual difi'erence. The specimen in the Museum of Paris 

 presents indications of black hairs on the extremities ; we have speci- 

 mens in our museum in tlie livery of moult ; others are wholly black, 

 with the excejition of a yellow stripe on the inner part of the feet, and 

 under the tail. 



t On comparing in our museum specimens of tlie Tiger of Corea 

 with those of Java, we may convince ourselves of tliis effect of climate, 

 particularly on examining the relative thickness of the tail : in the first, 

 tills member appeirs about the thickness of the arm ; in those of Java 

 it has that of a man's thumb.
