Scytalopus sylvestris Tacz. 



Scytalopus sylvestris Tacz. P. Z. S., 1874, p. 138 (Pallaypainpa, cen. Peru). 



Range. — Peru northward to the Temperate and Alpine Zones of the 

 Central (and Eastern?) Andes of Colombia and northeastward to the Sierra 

 of Merida, Venezuela. 



Remarks. — I refer to this species, of which I have seen no authen- 

 tic specimens, an adult female, from the Paramo of Santa Isabel, in 

 the Central Andes. It has the forehead grayish, the rest of the 

 upperparts somewhat light mummy-brown, the feathers of the back 

 narrowly margined with black; the tail is somewhat browner than 

 the back; the underparts are deep neutral gray; the flanks, ventral 

 region, and under tail-coverts barred with black and ochraceous- 

 tawny. A young male from the same locality is passing from Juv- 

 enal into adult plumage. It resembles the adult but has more 

 barred feathers in wings and on the nape, and the three remaining 

 tail-feathers of the juvenal plumage are distinctly barred with 

 black and ochraceous-tawny. 



To this species I also refer four specimens taken in the Temperate 

 Zone of the Andes of Merida, Venezuela. They have the flanks 

 paler, abdomen whiter, tail and upperparts blacker, but these dif- 

 ferences are at best racial and probably only individual. 



A Venezuelan specimen in molt has enough of the postjuvenal 

 plumage remaining to show that it is distinctly barred with ochra- 

 ceous-tawny above as well as below. 



Possibly our birds may not be true Scytalopus sylvestris but they 

 agree too closely with Taczanowski's description of that species to 

 warrant separation from it without comparison with Peruvian 

 specimens. 



Although this species more nearly resembles S. magellanicus 

 (Gmel.) than does any of the other species here considered, it is not 

 clear whether it is a representative of that species. 



Specimens examined. — Colombia: Parama of Santa Isabel, 2; 

 Venezuela; Paramo de Conejos, Sierra of Merida, 4.
