The Marbled Quail was first described by Gould from specimens obtained at 
Santa Fé de Bogoté. It is very closely allied to O. guianensis, some examples 
examined, especially one from Lion Hill, Panama, approaching that species very 
closely. Mr. Bangs® is of opinion that the Chiriqui bird, which he says is darker, 
should be separated from true 0. marmoratus, and has named it O. castigatus. The 
species appears to frequent the forests, and was met with by Tschudi in the Andes of 
Peru at elevations of from 4000 to 7000 feet. Its habits are unknown.

The chestnut crown and under surface of the body distinguish this species, the black 
face and throat being also conspicuous features. The type specimen from Tucurriqui, 
Costa Rica, is probably a female, as it agrees with a bird of this sex obtained by 
Mr. Underwood at Miravalles. A male from Veraguas sent by Arcé has the crown of 
a somewhat paler chestnut colour, and the mantle of a more uniform dark olive-brown, 
not showing the fine vermiculations of the Costa Rican female, while the light spots 
at the end of the inner webs of the inner secondaries are not visible. 
Very little is known respecting the habits of the Black-eared Quail. Like its 
allies, this species inhabits the forest. Mr. Richmond’? met with a flock of rather 
more than a dozen on the Rio Escondido, and when flushed they took refuge in the 
branches of the trees, afterwards flying off into the forest two or three at a time. 
Mr. Underwood obtained a single specimen at Miravalles 1°, but no more were seen, 
and it appears to be a scarce bird.
