Inhabits South America. 



We have three very distinct species of this genus in the British Museum collection, viz. : 



1 . With short, close, yellowish grey fur, with three equal, narrow, elongated streaks on the head ; which 

 appears to be the Simia trmrgata of Humboldt, described from a specimen which had lost its external 

 ears : hence it has been formed into a genus under the name of Aotus. Lesson has called the same spe- 

 cies N. Duruculi, and Schinz, N. Humboldtii. It is the N. trimrgatus of the British Museum Catalogue, and 

 probably the N. mciferans of Spix, and the Northern Miriquina of M. Natterer. 



2. With short close fur, like the former, but of a darker colour, with two white and three black tri- 

 angular spots on the forehead. This is the species here figured. 



3. The species from Santa Fe de Bogota, which is rather yellowish grey, but with long, very dense fur, 

 and with three indistinct blackish spots on the lower edge of the forehead. In the ' List of the Mammalia 

 in the British Museum ' I regarded it as a variety of the preceding species, but having procured another 

 specimen, and examined others, from the same country, I am convinced it is a distinct species.
