ORTYX, Stephens. 
Ortyx, Stephens, Shaw’s Gen. Zool. XI, 1819. Type Tetrao virginianus, E. 
Ch. —Bill stout. Head entirely without any crest. Tail short, scarcely more than half the wing, composed of moderately 
soft feathers. Wings normal. Legs developed, the toes reaching considerably beyond the tip of the tail; the lateral toes short, 
equal, their claws falling decidedly short of the base of the middle claw. 
The genus Ortyx embraces numerous species, more or less resembling the well known Bob- 
white of the United States. They are chiefly confined to Mexico, Central America, and the 
West India Islands. An Ortyx cubanensis, from Cuba, is said by Cabanis to resemble 0. texanus 
much more than virginianus.
