 wliile that on lower aspect of the forearms and legs, very

 whitish hairs, which extend on to the sides of the neck and 

 form a prominent whitish patch. Limbs not very different

 surface of hands and feet like body on the metapodials, the 

 digits dark brown. , 



Skull very like that of lorentzi, but the bullae are less 

 swollen. Incisors slightly smaller, so that the row of four 

 measures about 4*2 instead of 5 mm.

Hah. Weyland Mountains, Dutch New Guinea. Type

Type. Adult male. B.M. no. 21. 8. 1. 11. Original num- 

 ber 51. Collected 20th December, 1920. Four specimens. 



Assuming the identity of the Goliath Mountain specimens 

 described in 1911 with the melanistic P. lorentzi, the present 

 handsome animal may be readily distinguished by the white 

 patches behind its ears, and by the brown instead of rufous 

 lower aspect of the forearms and thighs.
