Bates states (1. c.) "in the neighborhood of Para a reddish colored 

 species prevails, (M.) beelzebul; in the narrow channels near Breves 

 I shot a large, entirely black kind; another yellow-handed species, 

 according to the report of the natives, inhabits the Island of Marajo, 

 which is probably the M. Havimanus of Kuhl" ; {ruHmanus is probably 

 intended = A. beelzebul) ; "some distance up the Tapajos the only 

 howler found is a brownish black species." The type of Mycetes dis- 

 color Spix, is in the Munich Museum. It is a rather small black animal 

 and may be an immature example of the present species or A. caraya, 

 but more probably of A. beelzebul, as A. caraya has a more southern 

 habitat. Spix procured his specimen at Fort Carupa on the Amazon.
