_Thryothorus berlandieri_, COUCH, BAIRD, Birds N. Am. 1858, 362,
pl. lxxxiii, fig. 1 (New Leon); Rev. 124.
SP. CHAR. 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-coverts 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. Valley of Rio Grande.
The distinctive features of this race will be found indicated on page
141. This form bears to the _T. ludovicianus_ about the same relation
that _Harporhynchus longirostris_ does to _H. rufus_; and is hardly to
be considered a distinct “species” from it. It should be noted that in
both cases the lengthened bill and deeper color belong to the Rio
Grande. It has not yet been met with north of the Rio Grande, but
doubtless extends into Texas. Nothing is known of its habits.
