nor do they agree with T. 1. berlandieri (sec Baird, Birds of 

 North Am., 1858, p. 362, pi. lxxxiii, fig. 1). The type and two 

 other specimens collected by Lient. Couch in 1853 are in the col- 

 lection of the National Museum. (For previous records of these 

 Rio Grande Wrens, see Bulletin U. S. Geological and Geo- 

 graphical Survey, Vol. IV, No. 1, p. 8, and note by Dr. Cones; 

 also ibid., Vol. I, No. 3, p. 3S3 ; also Ridgway's 'Manual of 

 North American Birds,' foot-note on p. 550.) 



After the capture of three specimens of T. 1. berlandieri in 

 1853, so long an interval elapsed before any more specimens were 

 taken that Mr. Ridgway considered the form not well enough es- 

 tablished to be given a place in his "Manual.' Last year I ob- 

 tained from my collectors three fine specimens of berlandieri 

 from Victoria, Tamaulipas, Mexico, and this year I have received 

 fifteen adults and one young from Nuevo Leon, Mexico, from the 

 exact localities visited by Lieut. Couch in 1853. Thryothorus 

 I. berlandieri can assuredly now be considered what Mr. Ridg- 

 way predicted, — a good tenable race ; in fact it seems to me to be 

 worthy the full specific rank given it by Prof. Baird. It is this 

 accumulation of berlandieri specimens from northeastern Mexico 

 that makes it possible to recognize the real status of the Rio 

 Grande birds, for which I propose the name 



Thryothorus ludovicianus lomitensis. Lomita Wren. 



Sp. Char. — Adult breeding plumage: Upper parts grayish brown, 

 grayer on head, reddish on rump; white spots on rump numerous and 

 not wholly concealed. Auriculars brown; sides of neck behind auricu- 

 lars conspicuously streaked (sometimes barred) with white and black. 

 Wings and tail lighter than hack; edges of wing and tail barred conspic- 

 ously with white and black; tail bars broken up more or less, showing 

 great irregularity. Under parts : throat and breast white, the latter 

 faintly washed with buff; belly buff; flanks barred more or less indistinctly 

 with brown ; under tail-coverts barred black and white. 



Adult winter plumage : Upper parts chocolate brown, the under parts 

 more strongly washed with buff and occasionally becoming quite tawny. 

 On account of the seasonal variation of these Wrens I have designated 

 three examples as types: a male and a female in the faded plumage of 

 the breeding season, and a male in the darker plumage of winter.
