Spix, who discovered this species in the forests of the river Solimoens (Upper Amazons) in 1820, 

 describes it very concisely as "maximus, familiaris, vociferans, immaculate plumbeo-niger, 

 subtus nigro-plumbeus, axillis subspinosis," and tells us that it is there well known as the 

 " Peru do Mato," or " Dog of the AVood." More recent explorers have supplied the cabinets 

 of Europe with numerous specimens from the same district. Hauxwell got it at Pebas, 

 Edward Bartlett at Nauta and Sarayacu, and Whitely at Yquitos. From Peru M. nigrifrons
