Specinneiu examined. — Only the type. 



CYNOMOLGUS CAGAYANUS, new species. 

 CAGAYAN SULU MACAQUE. 



%>6'.— Aault male (fskin and skull), Cat. No. 125325, U.S.N.M., 

 collected on Cagayan Sulu Island, Sulu Sea (near Borneo), February 

 25, ll.>04, by Edgar A. Mearns, (Original number, 5771.) 



Characters. — Size, the smallest of the Philippine Macaques; about 

 three-fifths the bulk of C. phiUpplnensh ox C. iiiindanensis. 



Color. — The fresh skin was put in alcohol, in w^hich iiuid it was 

 shipped to the Museum. From \\\y recollection I should say that its 

 color is now considerabh^ paler than when fresh. At present the 

 upperparts are olive-brown, with scarcel}^ a trace of chestnut or burnt 

 umber on the head; sides of head brownish gray, face smoke gray; 

 forehead gra\'isli in front, behind which a crest of stiff black hair 

 arises; underparts pale drab-gray ; outer surface of limbs like the back 

 abov'e, ))ut fading at the knee and elbow joints to dral)-gra3^ upon the 

 forearms, hands, legs, and feet; tail above slate-black at base, fading 

 to mouse gi'a}" toward the end, and drab-gray on the under side. 



Skull and teeth. — The skull of the type is similar to that of the 

 male of C. 'miudanensi^., Init is only as large as the female of that 

 species, the proportion of w^eight in the sexes being as 9 to 15. The 

 size would be, therefore, only three-fifths of that of C. mindanensis. 

 In form the skull (juite closely resembles that of C. suluenms/ but the 

 dentition is relatively much heavier. The audital bullie are small, 

 but inflated and prominent apically.
