86 SIMIIDiE. 



stances attending the life of if. lasioHs were unfavourable to the full development 

 of the animal, and it is possible, as A. M. -Edwards says, that it may attain to a 

 considerable size, but it can hardly equal M. nemestrinus. The scapula, one of the 

 few bones of the male which have been preserved, indicates a large and powerful 

 animal, and considerably exceeds in size any scapula of M. rhesus that has come 

 under my observation, from which it is chiefly distinguished by its greater breadth. 

 The male, as stated, is supposed to have come from Tse-chuen, which is a very 

 mountainous province of Western China, and the female from the mountains of 

 Tcheli to the north-east.

 Macacus rhesus^ Sclater, Proc. Zool. Soc. 1871, p. 222. 



Swinhoe, in a letter addressed to Dr. Sclater^ on the 7th September 1866, 

 described a monkey from North Lena Island, Hong-Kong, under the name of Sancti- 

 johannis, after Commander St. John, from whom he had received the animal alive, 

 and which was forwarded to the Collection in Kegent's Park, London. Commander 

 St. John described it as a female about four months old, and Swinhoe characterised 

 it thus : " Eyes bright hazel ; face and ears flesh-coloured ; cheeks with a black tuft 

 on either cheek like whiskers ; skin of nude parts tinted with blue and sparsely 

 greyish brown, covered with hairs of a light grey ; the hairs on the belly, bujff ; fur 

 of upper parts washed with bufi^, which is lighter on the head, and brickdust-red 

 round and about the rump. Tail 4J inches, blackish; callosities flesh-coloured. 

 Pace narrow, somewhat projecting."
