Swinhoe found them very common about the jungles of Nychow, 

 southern Hainan. 



40. Semnopithecus nemaeus (Linn.). 



Semnopithecus nemc^us MEYER, P. Z. S., 1892, .665 (in litt.). 



Dr. Meyer (/. c.) has reported the receipt at the Dresden Museum 

 of a specimen of this species from the island of Hainan. He says: 

 "Not being aware that Semnopithecus nemceus has been recorded 

 from the island of Hainan, but only from Cochin China, I beg to 

 state that the Dresden Museum has recently received a male specimen 

 of this monkey together with other objects from there." 



This is the only evidence I have for the inclusion of this species in 

 the present list.

Du Halde (/. c.) reported, in 1735, the existence of a great black 

 ape in Hainan, but referred to it as rare, and gave of it little additional 

 information. Swinhoe, in 1870, referred to Du H aide's account, and 

 confirmed the occurrence of such an animal in the island, but was un- 

 able to secure specimens, and was unable even to see a living example, 

 .although the species was well known to the natives and was sometimes 

 kept by them in confinement. 



In 1892, Thomas described a gibbon from Hainan, presumed to 

 be the species doubtfully referred by Swinhoe to Hylobates pileatus 

 Gray, the description being based on a specimen presented to the 

 British Museum by Mr. W. T. Lay, "to whom it was brought alive 

 from the island, and in whose care it lived for about four years in 

 China." The animal is described as wholly jet black, and while re- 

 sembling Hylobates hoolock, differs from it, and from all other known 

 species, "by the entire absence of the white superciliary streak." 



Pocock, in 1905 (/. c.) , published some interesting observations on 

 a female specimen then living in the Gardens of the London Zoological 

 Society, procured in the island of Hainan, on July n, 1897.
