ECUADOR HOWLER MONKEY. 



Type locality. Vinces, west coast of Ecuador. Type in Zoological 

 Museum, Turin. 



Genl. Char. Similar to A. palliata, but general color chocolate 

 brown instead of black. 



Color. Male adult. General color chocolate brown, the hairs 

 at base yellowish fulvous, with yellowish tips. Hair on flanks long, 

 golden yellow. Hands, feet and tail chocolate brown. 



Female adult. The chocolate brown color of the male is less con- 

 spicuous, the general dominating hue being yellowish fulvous. 



Young Male. General color dark gray, many hairs being of a 

 golden hue particularly at the tips. 



M. Festa states (1. c.) that this species is nearly extinct in the 

 Province of Vinces, and is only found in certain places on some planta- 

 tions of cacao, where hunting is forbidden. 



It seems to have its nearest relationship with A. palliata.
