List of specimens. 



THEIOTHOEUS BEELANDIEKT, 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 cj verts 

 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 hears a very close resemhlance to the T. ludovicianus. It is, however, smaller, 

 the hill longer and more slender, the notch more conspicuous. The wings are proportionally 

 shorter and more rounded, the primaries projecting less heyond 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 Gatherpes 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 

 difierence as in ludovicianus. 



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

 Matamoras, Mexico.
