It should be noted that aside from these specimens from Tumaco and 

 Barbacoas we have but one specimen of this species from that part of the 

 Pacific Coast region of Colombia lying between Tumaco and Alto Bonito. It 

 is worthy of comment that while in the Eastern Andes House Wrens cross the 

 range through the Temperate Zone, in the Central and "Western ranges they 

 are not found above the subtropics. It is also surprising that in the first- 

 named range three forms of T. musculus occur while, if we except the 

 Tumaco region, only one is found throughout the whole region west of the 

 Magdalena River.

This strongly marked race occupies the Temperate Zone of both slopes 

 of the Eastern Andes descending to the upper ftargin of the Subtropical 

 Zone. The upperparts are appreciably darker than in striatulus while the 

 underparts from bill to vent are uniform vinaceous-buff to wood-brown, 

 with no white areas. On the western slope a native-collected specimen 

 labeled "Anolaima, Feb. 4, 1913" is intermediate toward striatulus while 

 on the eastern slope a specimen from Quetame approaches T. m. neglectus. 

 The type of columbm loaned me by Mr. Stone is typical of the race for which 

 it stands.

(34366) Troglodytes musculus neglectus subsp. nov. 



Char. Subsp. — ■ Similar to T. m. striatulus but rump, upper tail-coverts, flanks and 

 ventral region more rufescent; the tail shorter. 



Type.— No. 122488, Am. Mus. Nat. Hist., c? ad., Buena Vista (above Villa- 

 vicenoio), alt. 4500 ft., Eastern Andes, Colombia, March 8, 1913, F. M. Chapman. 



Remarks. — This form, which is based on ten specimens, all from Buena 

 Vista, is in color an intermediate between striatulus and clarus, of both of 



1 Intergrades toward T, m. albicans. 



2 One intergrades toward T. m. columbx.
