Most like JI. I/runneicapilln-s affinis, the under parts very similar, 

 but under tail-coverts barred, instead of spotted, with black; pileum 

 grayish brown, with feathers dusky centrally; general color of back 

 much more grayish, the black streaks much broader; lateral rectrices 

 broadly tipped with dull white, but not barred with white, except 

 sometimes (on outermost rectrix only) toward end. 



Adults {sexes (dike). — Pileum and hindneck grayish brown, each 

 feather dusky centrall}', producing a squamate appearance; general 

 color of back, scapulars, and rump grayish brown or brownish gray, 

 this broken by conspicuous, sharply defined broad white streaks, each 

 margined along each side by a broad black streak; upper tail-coverts 

 barred with black or dusky; middle rectrices pale grayish brown or 

 brownish graj', broadly barred or banded with dusky; other rectrices 

 dusky, broadl}' tipped with white, the white terminal area becoming 

 pale brownish gray at tip, often forming a distinct narrow terminal 

 band; outer web of lateral rectrix broadly barred or transversely 

 spotted with white, these bars or spots becoming more grayish basally; 

 outer webs of other rectrices broadly barred with black and pale 

 brownish gray; wings conspicuously barred and spotted with brown- 

 ish gray, white, and blackish; a broad superciliary stripe of white; 

 lores gi'ayish; a broad postocular streak of grayish brown; rest of 

 sides of head, with under parts, white, the flanks and anal region tinged 

 with brownish buff; auricular region finely (sometimes obsoletely) 



« Professor Sumichras^t is of the opinion that Jalapa, aa a locality for this species, 

 is an error, the specimens so labeled probably coining from a higher altitude. 



'' A specimen said to be from the Valley of Mexico is precisely like Vera Cruz 

 examples.
