Color. — Like all the species of this oroiip the pelage of the upper- 

 parts and outer surface of limbs is annulated with light and dark. The 

 light rings and glossy texture of the hair give these parts a changing 

 hue when viewed in difterent lights. The general effect is as follows: 

 Upperparts mununy l)rown, the hairs everywhere aiuudated with 

 l)lackish; top of head strongly tinged with chestnut; sides of head 

 gi-izzled yellowish olive; forehead ornamented with a brow of stiti' 

 black hairs, scarcely separated from the naked orbits by a narrow 

 rim of short, brown hair, which is cut oli' V)y intervening black in the 

 center; underparts, including inner surface of limbs, scantil}" clothed 

 with pale drab-gray hairs of a very silky texture; genitals, broccoli 

 brown; outer surface of limbs, mummy brown, mixed with smoke 

 gray on wrists, ankles, feet, and hands; tail, grayish ])lack aI)ove, 

 hair brown below, with a gradual blending of these colors on the sides 

 of the tail.

Remarl-f>. — Measurements taken from skins of monkeys are so unsat- 

 isfactory that I have omitted them. Skulls indicate that the size of 

 the Luzon form is aljout the same as that from Mindanao, but the 

 smallei" size of the foramen magnum in all of the Luzon skulls would 

 indicate a more slender animal. 



Sjjcciwe/hs examined. — Four, two adult females and two immature 

 males, all from Batangas, Batangas Province, Luzon, Philippine 

 Islands.
