DESCRIPTION OF A NEW SPECIES OF PIPILO 

 FROM MOUNT ORIZABA, MEXICO. 



BY ULYSSES O. COX. 



While on Mount Orizaba, Mexico, as a member of Dr. Sco- 

 vell's party during the summer of 189 1 I made a small collection 

 of birds of the region which Mr. Robert Ridgway of the U. S. 

 National Museum has had the kindness to identify for me. 

 Among them Mr. Ridgway finds a Pipilo which appears to be 

 anew species. I have given it the specific name oi'izabce and 

 append here Mr. Ridgway's description and comparison with 

 related species. 



Pipilo orizabae Cox, sp. nov. 



"Sp. Char. — Most like P. maculatus Sw., but no black whatever on 

 upper parts, which are plain grayish brown; white markings of scapulars 

 and wing feathers nearly obsolete, sides and flanks much paler in color, 

 and size somewhat greater. 



'■'■Adult male (No. 132,72^, U. S. National Museum, Mount Orizaba, ^-f- 

 Mexico, alt. it.ooofeet; Ulysses O. Cox): Above uniform dull grayish 

 brown, slightly tinged with olive, scarcely darker on the head; outer- 

 most scapulars with marginal elongated spots of white, and lowermost 

 middle and greater wing-coverts with more roundish terminal spots of 

 the same; no white markings on remiges, but primaries edged with 

 light brownish gray; tail (except middle feathers) very dark brown, the 

 three outermost feathers with a large, abruptly denned, white spot termi- 

 nating inner webs, that on the lateral feather nearly 1 inch long. Chin, 

 throat, and chest blackish brown, gradually lightening on sides of head 

 and grading gradually into color of crown, the throat spotted with white 

 beneath the surface; sides, flanks, and under tail-coverts ochraceous- 

 buff, somewhat deeper anteriorly; median lower parts white, broadest 

 and purest anteriorly, next to blackish brown of the chest. Bill black; 

 legs light brown, toes darker. Total length (skin), 8.30 1 ; wing, 3.35; 

 tail, 3.85; exposed culmen, 0.60; tarsus, 1.17; middle toe, 0.78. 



"This bird is obviously quite distinct from both P. maculatus 

 and P. macronyx, as well as their hitherto described allies. 

 The pure white and abruptly defined tail-spots, and entire
