Bangs — Notes on Birds from Western Colombia. 159 



P. stictonota (Berl.) of western Bolivia, three well marked geographic 

 races should be recognized, as follows: 



Premnoplex brunnescens brunnescens (Scl.). 

 Central and western Colombia to Peru. 



Wings, tail and groimd color of under parts all very dark brown ; spots 

 on under parts large, clearly defined, fulvous; throat, ochraceous. 



Premnoplex brunnescens coloratus (Bangs). 

 Sierra Nevada de Santa Marta, Colombia. 



Wings, tail, ground color of under parts, and back, all richer or redder 



brown, less blackish, most of spots on under parts and throat ferruginous. 



Premnoplex brunnescens brunneicauda (Lawr.). 



Costa Rica, Chiriqui and Veragua. 



Much grayer or more olivaceous brown throughout, spots on under 

 parts much paler and less sharply contrasted with ground color, and less 

 distinctly bordered with blackish; throat dull fulvous. 



Henicorhina leucophrys guttata (Ilartl.). 



Three specimens, two adult males, one youngish female, San Antonio, 

 western Colombia. 



These three skins belong to a form of the gray-breasted wood wren that 

 appears to me well characterized and that tallies as well as can beexpected 

 with Hartlaub's short description of bis Troglodytes guttalus from New 

 ( irenada.* 



Kidgway, in part III of his Birds of North and Middle America, skil- 

 fully untangled the races of Henicorhina and arranged them under five 

 species in a most satisfactory way. He, however, said he was unable to 

 consult Hartlaub's description of Troglodytes guttata s and Suggested that 

 that bird might be his Henicorhina hilaris bangsi. There is in the library 

 of the Museum of Comparative Zoology at Cambridge, Mass., a copy of 

 Hartlaub's work, and the short Latin description of Troglodytes guttatus 

 seems to me certainly to have been drawn up from a gray-breasted, black- 

 headed Henicorhina and not from a member of the hilaris group. 



The three skins in the present collection do not agree in subspecific 

 characters with any of the races of Henicorhina leucophrys recognized by 

 Kidgway, differing from H. leucophrys leucoplirys (Tsch.) of Peru in 

 having the black postocular streak not extended below the eye, but as 

 in H. leucophrys colina (Bangs) of Costa Rica and Chiriqui, the cap, 

 however, is sooty blackish throughout in the males, scarcely shaded at 

 all with brownish medially; the female ( which also appears to be young- 

 ish) has the cap brownish medially. From H. leucophrys colina the 

 Colombian birds differ in several characters in addition to their blacker 

 1 leads, more noticeable of which are, that the white superciliary streak is 

 much wider and is broadly continued forward directly to nostril; throat 

 whiter, less grayish and less streaked with black; breast slightly paler 

 gray and flanks decidedly paler brown; brown of back of the same shade 

 as in H. I. colina.
