extending to the forehead, but a specimen from Travancore in the 

 British Museum has rough hair like M. pileatus devoid of annula- 

 tion, and an unusually long topknot. 



Habits. Very similar to those of other members of the genus. 

 This is the common monkey, tame or wild, of Southern India, found 

 both in wild jungles and in populous towns, where it pillages the 

 shops of the dealers in fruit and grain. Jerdon says " it is the 

 most inquisitive and mischievous of its tribe, and its powers of 

 mimicry are surpassed by none." I do not think that it can excel 

 M. rhesus in inquisitiveness and mischief, but I believe that it is, 

 on the whole, more docile.

Simla pileata, Shaw, Gen. Zool. i, pt. 1, p. 53 (1800). 

 Macacus sinicus, Kelaart, Prod. p. 8, nee Linn. 



Macacus pileatus, Blyth, Cat. p. 9; Anderson, An. Zool. Res. p. 91 ; 

 id. Cat. p. 61. 



Ealdwa, Cingalese. 



Hair rather long, wavy and rough, that of the crown forming a 

 topknot radiating from the vertex, and considerably lengthened, 

 extending in front nearly to the eyebrows. Tail nearly as long as 

 head and body. Caudal vertebrae 24. The skull is similar to that 

 of M. sinicus. 



Colour. Rufous or yellowish brown above, white or whitish below. 

 The upper surface of the tail, hands, and feet sometimes more 

 dusky. Fur hair-brown at base, tipped and sometimes annulated 

 with rufous or yellow. Face and callosities flesh-coloured. Ears, 

 palms, and soles dusky. 



Dimensions. Head and body of an adult male 21 inches, tail 18 

 (Kelaart). Schlegel gives 20 and 23 inches, probably from skins. 

 A male adult skull is 4*9 inches in extreme length, 3 - 5 in zygo- 

 matic breadth. 



According to Kelaart the present form is of less robust make 

 and smaller size than the Southern Indian form, but it is very 

 doubtful if there is any constant difference. For my own part, 

 I doubt if the two are entitled to specific distinction. 



Distribution. Ceylon, throughout the island. 



Habits. Precisely the same as those of M. sinicus. Kelaart says 

 that the latter is more intelligent and less mischievous ; but, as 

 already remarked, the two are probably mere varieties of the same 

 species. M. pileatus is the monkey commonly kept tame in Ceylon, 

 and carried about by jugglers and itinerant mountebanks for the 

 amusement of children, exactly as M. rJiesus is in Northern and 

 M. sinicus in Southern India. It may be mentioned here that 

 those who have only seen monkeys in Europe, and especially in 

 cages, have in general a very imperfect idea of the intelligence, 

 love of fun, and power of mimicry that these animals possess.
