4. PRESBYTIS OBSCURA, SPBSP. (>). 

 (J imm. Ban Kok Klap, Bandon, N.E. Malay Peninsula. 2nd July, 1913. 



An immature male (greatest cranial length 83.6 mm.) differs 

 from normal adults in being of a pale cafe-au-lait colour ; the 

 occiput, nape, median dorsal line and middle areas of the limbs 

 being creamy to liglit buff with the forehead sides of the face and 

 neck, chest, shoulders, sides of body, hands and feet, pale snuff 

 brown. At a casual glance this specimen might be referred to the 

 preceding race, from which however it can at once be distinguished 

 by the arrangement of the hair on the forehead. 



A form of Pr. obscura was common in tlie district, though we did 

 not collect other specimens.
