THRIOTHORUS BERLANDIERT, Couch. 



Sp. Ch. — 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 c verts 

 and sides of the body barred witli dusky. E.fposed surface of wings and tail barred throughout with dusky. Legs flesh color. 

 Length, 5.25; wing, 2.25 ; tail 2.12. 



//„(). — Nortlieastern Mexico towards the Rio Grande. 



This species bears a very close resemblance to the T. 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 prqecting 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 ludovicianus and almost as deep as in Oatherpes 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 

 difl'arence as in ludovicianus. 



This species has been named by its discoverer, Lieut. Couch, after Dr. Berlandier, late of 

 Matamoras, Mexico.
