20 CEECOPITHECID^. 



Distribution. Originally described from specimens collected by 

 Sir A. P. Phayre in Arakan. Anderson has since referred to this 

 species specimens from Upper Burma, and a young animal from 

 Perak, Malacca. The latter identification is very questionable, as 

 the Malay peninsula is inhabited by the true pig-tailed Monkey, 

 M. nemestrinus. A few individuals have been introduced into the 

 Andaman Islands, but the species is not indigenous. 



Habits. Scarcely anything is known, except that the young and 

 females are docile' in captivity, old males fierce. In this, as pro- 

 bably in most other respects, this species is very similar to the 

 next.

Mijouk-padi, Burmese ; Ta-o-ti, Burmese of Tavoy ; Bruh, Malay. 



Body stout ; limbs long and powerful ; muzzle in adults much 

 produced. Fur slightly lengthened over shoulders, and short 

 generally. Hair radiating in centre of crown, but not surrounded 

 by the distinct horseshoe-crest of M. leoninus (there is, however, an 

 approximation to it in some specimens). Tail very slender, rather 

 more than one third the length of the head and body. Caudal 

 vertebrae 18. 



The muzzle, in old male skulls especially, is greatly produced, 

 and much resembles that of the Baboons (Cynocephalus) in form. 

 The orbits are nearly as high as broad. 



Colour. Crown of the head dark brown or black, except at the 

 sides ; a broad black stripe extends throughout the middle of the 

 back in many specimens, becoming broader on the rump ; but in 

 young animals and in some adults the back is brown throughout. 

 Fur of upper surface generally yellowish brown, but varying from 

 pale orange-brown to blackish brown in different specimens ; lower 

 parts greyer brown or albescent ; hands and feet sometimes darker 

 than the limbs. Tail black above, light yellowish brown below. 

 The fur on the upper parts and the outside of the limbs is closely 

 annulated with yellow and brown ; basal portion of hair grey. 



Dimensions. Tickell gives as the measurements of an old male 

 from Ye : Head and body 18| inches, tail 7|, hand 3f , foot 6, 

 height at shoulder 16 ; the size, however, varies much, and many 

 individuals attain a much greater development, rivalling, as 

 Anderson remarks, a good-sized mastiff both in height and strength. 

 Of two skulls of adult males in the British Museum one measures 

 6-5 inches long from the occiput and 5 from the foramen, by 4-2 

 broad across the zygomatic arches ; whilst another male adult skull 

 is only 5'78 and 4-4 long and 3'8 broad ; and a third from Mergui 

 5, 3-6, and 3-5. Females must be very nearly as large as males ; 

 the skull of a very old specimen from Tenasserim is 6-2 and 4-2
