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

 Eritish Museum has rough hair like M. inleatus 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 

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

 on the whole, more docile. 



11. Macacus pileatus. 7'o(/»e Monkei/. 



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

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



Macacus pileatus, Blyth, Cat. p. 0; Anderson, An. Zvoi, Hes. p. 91 ; 

 id. Cat. p. 61. 



Raldwa, 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 vertebne 24. The skull is similar to that 

 of M. sinicus. 



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

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

 dusky. Eur 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 iiiches 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 dift'ei-ence. Yov my own part, 

 I doubt if the two are entitled to specific distinction. 



Distrihution. 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. 31. inleatus is the monkey commonly kept tame in Ceylon, 

 and carried about by jugglers and itinerant mountebanks for the 

 amusement of children, exactly as 31. rhesus is in Northern and 

 31. 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, aixd power of mimicry tliat these animals possess.
