THRIOTHORUS BERLANDIERI, Couch. 
Sp. Cu.—Exposed portion of bill nearly as long as the head. Above, dark rusty brown, most vivid on the rump. A whitish 
streak over the eye, bordered above with brown. Chin white; rest of under parts dark brownish red ; the under tail cdverts 
and sides of the body barred with dusky. Exposed surface of wings and tail barred throughout with dusky. Legs flesh color. 
Length, 5.25; wing, 2.25; tail 2.12. 
Hab.—Northeastern Mexico towards the Rio Grande. 
This species bears a very close resemblance to the 7’, ludovicianus. It is, however, smaller, 
the bill longer and more slender, the notch more conspicuous. The wings are proportionally 
shorter and more rounded, the primaries projecting less beyond the secondaries ; the first quill 
is larger. The tail is shorter and considerably more graduated. The colors above are darker, 
especially the reddish of the rump. The under parts are of a much deeper reddish brown, 
nearly as dark as the rump of /udovicianus and almost as deep as in Catherpes mexicanus ; the 
sides under the wings in two specimens exhibit distinct, though distant bars of dusky, not seen 
in any skins of the other species before me. 
The lateral tail feathers are nearly half an inch less than the others, nearly twice as great a 
difference as in ludovicianus. 
This species has been named by its discoverer, Lieut. Couch, after Dr. Berlandier, late of 
Matamoras, Mexico.
