chest >ind middle area of belly replaced by dull pale cinnamon, 

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

 prominent in lorentzi, is quite absent, these parts being 

 simply dull greyish brown. Head mixed buffy and black. 

 Ears almost naked internally, the metentote with a few 

 ochraceous hairs ; externally they are finely clothed with 

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

 form a prominent whitish patch. Limbs not very different 

 from the body, the forearms above more cinnamon ; upper 

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

 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.

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

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.
