INTRODUCTION Ixxv 



Alouatta has but one species ursina; Pithecia two, P. satanas; and 

 P. MONACHA ; Ateleus onc, variegatus. Lagothrix also one, lago- 

 TRiCHA ; and Cebus three, C. a. pallidus; C. u. cuscinus; and C. f. 

 peruanus. In Bolivia, the last portion of South America in which Pri- 

 mates occur, four species are found : Callicebus donacophilus ; 

 Saimiri ustus ; Actus boliviensis ; and Alouatta sara. From the 

 above recapitulation it will be seen that the Brazilian Subregion is the 

 home of the Primates in the New World. Every genus save one, 

 QiDiPOMiDAS, is represented within its boundaries, and two, Cacajao 

 and Brachyteleus are not found elsewhere. On the eastern border 

 of the Neotropical region no Primate is found below the southern 

 limit of the Brazilian Subregion, but on the western side the Order has 

 its representatives in Peru and Bolivia of the Chilian Subregion. 



The geographical distribution of each species, so far as known, is
