Miller and Boyle secured an excellent series of ten specimens of this 

 species in that elevated region near the northern end of the Western Andes 

 known as the ParamUlo.. In general coloration it resembles Myornis senilis 

 with which, however, it has no close relation. Although approaching in 

 size and superficially resembling Scytalopus niger (Swains.), the more loosely 

 constructed rectrices and differences in the color of the young indicate that 

 it is not a representative of that species.

Merul[axis] grisei^collis Lafr., Rev. Zool., 1840, p. 103 ("Bogotd"; type exam- 

 ined). 



Found by us only in the Temperate Zone of the Eastern Andes near 

 Bogota. Examination of the type of Lafresnaye's Merulaxis squamiger 

 shows it to be based on the juvenal plumage of this species. Mr. Bangs 

 sends me, ia addition to the types of griseicoUis and squamiger, a Lafresnaye 

 specimen (No. 4854) labelled "Scytalopus erythropterus Lafr." I cannot 

 find that this name was published. The bird is a not fully adidt specimen 

 of Scytalopus griseicoUis. 



The whitish abdomen, unbarred tawny flanks and rump, and brownish 

 tail, distinguish the adult of this species. The juvenal plumage is con- 

 spicuously and evenly barred both below and above.

(1819) Scytalopus sylvestris Tacz. 

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



I refer to this species, of which I have seen no authentic 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 

 juvenal 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.
