SP. CH Male. Lores white. Throat white, encircled by a black band which starts near base of upper mandible and becomes 

 broader in front of the neck. A wliire line over the eye, commencing at the nostril and running laterally on the neck, bordered 

 above by a narrow line of black. Crown dark brown, margined with gray and tinged with rufous. Feathers on lower part of 

 hind neck dull black, id contra! parts eded with white and tipped with reddish brown. The shoulders and upper portions of the 

 back chestnut, mottled with deep brown, bordered with ash; the rest of the upper parts light brown, becoming lead color on

 by a general rufous tinge. The transverse bars on breast and abdomen are less rich and numerous. Bill horn color above, 

 lighter beneath. In all other respects like the male. Length ?| inches. 



This bird bears a close resemblance to the Ortyx virginianus, but the following differences may 

 at once be detected on comparing the two species: The 0. texanus is smaller, the rufous color 

 of the breast is paler, but forms a more perfect band in the male specimen. The transverse bars 

 on abdomen are twice as broad as those of the 0. virginianus, while the rich chestnut tinge 

 forming the prevalent tint on the back of the latter is replaced in the 0. texanus by a light 

 brown and a more general ashv hue.
