412 Chapman, The Genus Scytalopus Gould. . [oct. 



namon-brown, the back with subterminal black bars. The wings, 

 except in very worn plumage, are externally edged with a lighter 

 brown than the back, and at least the inner feathers are barred. 

 The rectrices are more or less barred in all but two of these thirteen 

 specimens. The underparts are grayish, of about the same shade 

 as in Myornis senilis and the flanks, ventral region, and under tail- 

 coverts are barred with black and ochraceous-buff or ochraceous- 

 tawny. 1 The feet in life are marked as "brown," "brownish" or 

 "yellowish" and in dried skins resemble those of S. griseicollis in 

 similar condition. 



All these specimens appear to be adult, but four lack the slight 

 trace of silvery white in the crown, while the remaining nine show 

 this mark in varying degrees. Possibly, as in <S. micropterus, this 

 character is individual. 



Instead, therefore, of being a representative of the black, uni- 

 formly colored bird to which the name magellanicus has by most 

 authors hitherto been misapplied, it is evident that this southern 

 form is more closely related to S. sylvestris. 



Specimens examined. — Chile: Valparaiso, 1. Ecuador: Zaruma, 

 2; Gualea, 1; Mt. Pichincha, 3. Colombia: Andes, W. of Popayan 

 (alt. 10,340 ft.), 8; Cerro Munchique, 9; Cocal, 3; Almaguer, 4; 

 Valle de las Pappas, 3 ; Laguneta, 3 ; Santa Isabel, 2 ; Sta. Elena, 1 ; 

 Fusagasuga, 1; El Roble, 2; El Pifion, 2. 



Scytalopus canus sp. now 



Char. sp. — With a general resemblance to S. niger (Swains.) 2 but adult 

 grayer throughout, the underparts paler than the upperparts, the center 

 of the abdomen grayer than surrounding parts; tail shorter, the feathers 

 narrower and softer, their barbs, apically, more or less separated; bill 

 shorter, feet and tarsi more slender; apparently closely resembling, and 

 perhaps representing, S. unicolor Salv. of Peru, but much smaller, the 

 female of the same color as the male. 



The juvenal plumage is evidently conspicuously barred above and below 

 with cinnamon-buff and therefore resembles that of S. griseicollis rather 

 than that of S. niger.
