 skull, total length, 114; occipito-nasal length, 95.8; intertemporal 

 width, 39.9; zygomatic width, 77.."); palatal length, 48.3; median 

 length of nasals, 28.1; length of upper molar series, 30.1; length of 

 mandible, 85.6; length of lower molar series, 37.2. This is a large

 It does not closely resemble any known species. 



PITHECUS MANDIBULARS, new species. 



Type-locality. — Sungei Sama, near Pontianak, Borneo. 



Type — Cat. No. 142225, U.S.N.M. 



General characteristics. — Similar in coloration to P.fascicularis, but 

 paler, less red, and the ascending ramus of mandible narrower, 

 higher, and with a backward inclination. 



Color. — Upper parts ochraceous buff; the hairs being gray at base 

 and then banded with black and ochraceous bull", the latter color

Measurements. — Total length, 1,015 mm.; t.-nl, 570; foot. 140; 

 skull, total length, 112; occipito-nasal length, 95.9; zygomatic width, 

 77; intertemporal width, 41.7; palatal length. 45; median length of 

 nasals, 26.9; length of upper molar series, 28; lengths of mandible, 

 80.9; length of lower molar series, 34.8' width of ascending ramus at 

 middle, 22.3; at top, 23.."); extreme perpendicular height, 38.1. 



The great difference in I he shape of the ascending ramus persists 

 in all the skulls, ami when compare. I with that of P.fascicularis 

 renders its narrowness and height conspicuous. The size of the 

 ascending ramus of /'. carimatst is about halfway betweeD those of 

 the Bornean and Sumatran macaques, and in the color of its pelage 

 it is quite unlike both.
