MACACA PAGENSIS Miller. 



1903. Macacus pagensh Miller, Smithsonian Miscellaneous Collections, XLV, 

 p. 61. November 6, 1903. 



Type locality. — South Pagi Island, east Sumatra. 



Geographic distri/mtion. — This animal is probably confined to the 

 Pagi Islands. 



General characters. — Like Macaca nemestrina., but size much less 

 (skull of female only 110 mm. in greatest lenofth). and color much 

 darker. 



Color. — Dorsal surface from forehead to base of tail clear bister, 

 darker than that of Ridgvvay, the drab underfur appearing irregularly 

 at surface when hair is disarranged. Sides of body and inner surface 

 of arms and legs isabella-color. Belly isabella-color, fading to light 

 fawn-color on chest and throat. Outer surface of arms light russet, 

 that of legs dark isabella-color, except on thighs, which are mostly 

 covered by an extension of the brown area of back. A similar but 

 less extensive wash covers proximal half of upper arm. Sides of 

 neck grayish cream-buli', in striking contrast with upper surface. 

 Cheeks and chin brown like that of back, but not quite as dark. 

 Hands and feet dusky brownish. Tail sprinkled with isabella-colored 

 hairs. "Callosities fleshy brown. Palms and soles light fleshy 

 brown.'"" 



6'/?'^///.— The skull (Plate XVIII, tig. 2) is very much smaller than that 

 of a slightly younger female of Macaca neinestrina (Plate XVIIl, tig. 1) 

 from Tapanuli Bay. Sumatra. In general form, however, the two do 

 not appreciably differ. The bony palate is concave laterally (when 

 viewed from below), but to a less degree than in the larger animal. 

 Its median line is nearly straight, and shows only a trace of the deep 

 longitudinal concavity so conspicuous in M. neiiiestrlna in region 

 between premolars. Audital bulla; a little more swollen anterolater- 

 ally than in M. nemestrina^ but this character may be purely individual. 

 Teeth as in Macaca neuiestrina^ but smaller throughout. 



Measurements. — See tables, pages 561-562. 



Specimens exandned. — The type of this species remains uni(|ue. 



Remarls. — Macaca pagensis is a well-marked insular species char- 

 acterized by its small size and dark color. The peculiarities of the 

 posterior molars of the type prove to be individual only, as they are 

 exactly reproduced in some of the specimens of 31. neinestrina now at 

 hand.
