158 Nelson New Birds from Southern Mexico. 



wings and tail and under tail coverts blacker and more strongly con 

 trasted with the brown; size about as in typical sinaloa. 



Remarks. This subspecies is based upon five specimens. Typical T. 

 sinaloa is exactly intermediate in coloration between russeus and cin- 

 ereus. 



Troglodytes brunneicoJHs nitidus, subsp. nov. 

 . Zempoaltepec Wren. 



Type. No. 143,058, $ ad., U. S. Nat. Mus., Biological Survey Coll. 

 From Mt. Zempoaltepec, Oaxaca, Mexico. Collected July 8, 1894, by E. 

 W. Nelson and E A. Goldman. 



Distribution. Humid forests on Mount Zempoaltepec, Oaxaca, and 

 adjacent parts of the Cordillera in northeastern Oaxaca (above 6,500 

 feet). 



Subspecific characters. Both adults and young differ from typical T. 

 brunneicollis in the deeper, or darker, reddish bistre-brown of upperparts, 

 and the darker and richer buffy-cinnamon on neck and breast; size about 

 the same. 



Remarks. This subspecies, based on two adults and one young of the 

 year, from the very humid forest on Mount Zempoaltepec, shows the in 

 fluence of the environment in its darker colors compared with T. brun- 

 neicottis, the type of which was taken in the more open and arid pine and 

 fir forest of the mountains at La Parada near Oaxaca City, central 

 Oaxaca. 



Henicorhina leucophrys f estiva, subsp. nov. 

 Guerrero Wren. 



Type.$o. 186,596, $ ad., U. S. Nat. Mus., Biological Survey Coll. 

 From Omilteme, Guerrero, Mexico. Collected May 23, 1903, by E. W. 

 Nelson and E. A. Goldman. 



Distribution. Heavy oak forested mountain slopes of the Cordillera of 

 western Michoacan and central-southern Guerrero (above 7,000 feet). 



Subspecific characters. Intermediate in coloration between H. leuco 

 phrys mexicana (Nelson) and //. leucophrys capitalis Nelson, but most like 

 the former from which it differs mainly in having crown, top of neck 

 and fore part of shoulders bistre brown; rest of back and rump slightly 

 duller shade of rusty rufous; bill longer. 



Remarks. The color of crown and top of neck in this form contrasts 

 more strongly with the rusty rufous of the rump than in mexicana, and 

 like the latter it shows no sign of the darker line on the sides of the crown 

 of H. I. capitalis.
