Alouatta palliata quichua Thomas. 



c?, ? ^/o; ? V9 1917, below Gnalea, about 3,000 feet alti- 

 tude. j" ^^8 1918, near Gualea, about 4,000 feet altitude; 

 $ ^^7 1919, near Gualea, about 4,500 altitude. 



The places where this fine series has been collected is 

 not very distant from the type-locality, so that the pree^ent 

 specimens are practically topotypes. The colour of the late- 

 ral mantle fringe is rather variable. In the finest old male 

 it is shiny black like the pelage generally, only with single 

 hairs somewhat sepia-coloured, or partly straw coloiired like 

 the ticks across the lower back, except a tuft near the in- 

 guinal region which is påle yellowish brown. In the other 

 male the mantle fringe is a påle shade of warm sepia. The 

 same is the case with the dorsal parts of the mantle, but 

 the lower aspect of the same is more similar to »snuff brown» 

 (Oberthur & Dauthenay 303, 3), but as the hairs are glossy 

 it looks still lighter. In another (female) the mantle fringe is 

 entirely glossy »snuffbrown» or yellowish brown of a some- 

 what lighter shade, and in the third it is much lighter, most 

 similar to »chamois» (1. c. 325, 1 & 2). Only the last one 

 has any considerable number of påle hairs at the tip of the 

 tail and bordering the naked under parts. These hairs are 

 putty coloured» (1. c. 311,4). On the tail of the other spe- 

 cimens there are only a few scattered longer hairs which 

 are somewhat brownish. They look, however, as faded and 

 eventually belonging to another pelage. 



The greatest length of the skulls of the males is 106,5 

 and 118 mm., and in the females about 106 mm. The con- 

 dylobasal length of the male skulls is about 97 and 107 mm. 



Ateles^ fusciceps Gray. 



2 (^(^ both collected near Gualea at an altitude of 4,000 

 feet; 1 $ V12 1920, S:to Domingo de los Colorados, 2,000 feet. 



The measurements of the largest skull agree nearly with 

 those published by Elhot (Eev. of the Primates II, p. 43) 

 except that the length of the uppér molar series is a little 

 greater viz. 27 mm. 



^ Elliot 1. c. has changed the vvellknown and correct name Ateles 

 into Ateleus, but it is, of couise, not the shghtest reason for such a pro- 

 ceeding.
