42 CEECOPITHECID^;. 



whitish. The nape and sometimes the middle of the back often 

 brownish. Mouth and eyelids whitish, remainder of face black. 



A female obtained by Mr. Davison at Bankasun, in the extreme 

 south of Tenasserim, has the crown of the head and middle of the 

 back hair-brown, sides almost black ; long hair of occiput, limbs, 

 tail, and underparts brownish grey ; feet black above, as usual. 



The young are of a vivid golden ferruginous colour, which soon 

 changes to dusky ash, the rufous colouring remaining longer on 

 parts of the head, throat, flanks, and thighs, and longest of all on 

 the terminal portion of the tail. Probably the female described 

 above retained the coloration of the young on the limbs and tail. 



Dimensions. In an adult male the head and body measured 

 21 inches, tail 32. An adult male skull from Tenasserim * in the 

 British Museum measures in extreme length 4-25, basal length 3, 

 and zygomatic breadth 3-5. In an adult female skull the corre- 

 sponding dimensions are 3 - 8, 2*7, and 2*85 inches. 



Distribution. Malayan Peninsula, Siarn, and the Tenasserim 

 provinces. 



25. Semnopithecus femoralis. The banded Leaf-Monkey. 



Semnopithecus femoralis, Horsfield, Appendix Life Sir T. S. Raffles, 

 p. 642 (1830) (no description) ; Martin, Charlesworttis Mag. N. H. 

 ii, p. 436 (1838) ; Cantor, J. A. 8. B. xv, p. 175 ; Horsf. Cat. 

 p. 10 ; Anderson, An. Zool Res. p. 30 ; id. Cat. p. 52 ; Thomas, 

 P. Z. S. 1886, p. 66. 



Two distinct radiating centres, one on each side of the forehead 

 behind the supraorbital ridge. Hair of the occiput elongate, 

 forming a crest as in S. obscurus. 



Colour. Blackish brown to black, except upon a varying portion 

 of the under surface, which is white, and always includes the lower 

 abdomen and inside of the thighs. Sometimes the latter colour 

 extends only to the knee, in other specimens it passes down the 

 inside of the leg to the heel, and also occupies the centre of the 

 chest, the inside of the arm, and the lower surface of the tail 

 except near the tip. 



Dimensions. Anderson gives head and body 19 inches, tail 22 ; 

 but no measurements from fresh individuals are available. 



Distribution. Borneo, Sumatra, and the Malay Peninsula, ex- 

 tending north into Tenasserim. A specimen was obtained by Mr. 

 Davison at Bankasun in South Tenasserim. 



Nothing is recorded of the habits of this species. 



I am strongly disposed to suspect that S. siamensis, Mull. & 

 Schleg. (S. albodnereus apud Cantor), is a grey form of this 

 species. 



* This is one of a large collection of Indian skulls in tho British Museum 

 labelled as presented by the late Dr. Oldbam. The collection was made by 

 Mr. W. Theobald, and entrusted by him to Dr. Oldham for presentation to the 

 Museum.
