136 DR. J. E. GRAY ON MAMMALS, ETC. FROM CAMBOJA. [April 9> 



From this spot on the forehead I am inclined to distinguish this 

 species or variety by the name of H. pileatus, though this is not 

 quite a distinctive mark, as both H. leucurus and H. agilis have the 

 crown more or less black. 



HyLOBATES PILEATUS. (PI. XXI.) 



Male. — Black ; back of head, back of body, and front hind legs 

 greyish ; forehead and circumference of the black spot on the crown 

 paler grey ; hands and tuft of long hair round the organ of genera- 

 tion white. 



The three specimens in this state are all nearly of the same size, 

 and appear to be adult. They only vary slightly in the size of the 

 coronal spot, and in the extent of the white colour on the hands. 



Female, — White ; back brownish white, slightly waved ; a large 

 ovate spot on the crown, and a very large ovate blotch on the chest, 

 black. 



These specimens are all of one size, and appear to be adult, and 

 are probably female; three have the teats well developed. They 

 vary in the size of the black chest spot, and in the colour of the 

 whiskers, thus : — 



a — b. White ; spot on the chest moderate, reaching only half- 

 way down the abdomen ; whiskers on side of face white. 



c. Brownish ; spot on chest larger, reaching farther down the 

 abdomen ; sides of the face black ; a few black hairs on the throat. 



d. Brownish ; side of the face, under the chin, and the whole of 

 the throat, chest, and belly black ; teats well-developed. 



Young. — Uniform dirty white, without any black spot on chest 

 or head.
