This species appears to have been described and figured as long ago as 1772, by the Abbe Rozier in the 
“ Journal de Physique,” but to have escaped the notice of ornithologists generally, until M. Temminck 
characterized it in his “Pigeons et Gallinacees” under the name of Perdix Sonninii, the appellation assigned 
to it by the Abbe not being retainable according to the rules of modern nomenclature. It is of the same 
size as Eupsijchortyx cristatus, but is distinguished from that species by the absence of spots on the chest, 
which part is of a uniform vinaceous or reddish grey. 
Habitat. Guiana, Caraccas, and the southern provinces of Mexico, from all of which countries I have seen 
specimens. M. Natterer states that it is also to be found “ in the bushes of the prairies on the banks of 
the Rio Branco in Brazil.” 
The figures represent the two sexes of the size of life.
