WHITE-EYELID MONKEY. 



This black monkey has a white ring around the eyes, 

 which gives it a peculiar appearance, and is probably the 

 negro monkey of Pennant. It is found in considerable 

 numbers in the interior, but is not so numerous as the 

 other monkeys, and the gibbons* Though heretofore re- 

 garded by Mr. Blyth himself, as identical with S. obscurus, 

 he has recently written me that he now considers it the 

 same as S. Phayrei, a new species, which he described 

 originally from Arracan specimens.

barbe's white-eyelid monkey. 



This monkey abounds in the forests of Yay, and is 

 nearly allied to the preceding species. Mr. Blyth says: 

 "It is' intermediate between P. Phayrei and P. obscurus; 

 but seemingly, distinct from both. There is no vertical 

 crest, as in the former; nor is the occipital hair length- 

 ened and conspicuously much paler, as invariably in the 

 latter species : but the shoulders and outride of the arm 

 are silvered in both specimens; and the under parts re- 

 semble those of P. obscurus. The tail is very slightly 

 paler than the body ; whereas in twelve adults of P. 

 obscurus (lying together before me, at the time of drawing 

 up this description), the tail is in every one much paler 

 than the body."
