° 1915 J Chapman, The Genus Scytalopus Gould. 417 



This a strongly marked species of the Alpine Zone of the Santa 

 Marta group known only from the specimens collected by W. W. 

 Brown for E. A. and O. Bangs. Thanks to Mr. Outram Bangs I 

 have examined six of these, including the type. In general color 

 this species resembles S. griseicollis (Lafr.) but it is darker below 

 and the rump, flanks, upper and under tail-coverts are barred 

 with black, though less distinctly than in any other of the northern 

 species having bars on these parts. 



The feet are heavier even than in S. micropterus, and the bill is 

 more laterally compressed, deeper at the base with the culmen more 

 ridged and elevated than in any other species of the genus known 

 to me. The bill thus approaches in form that of Myornis senilis 

 but the tail is short as in Scytalopus. 



Possibly S. latebricola represents the species to which I have ap- 

 plied the name of S. sylvestris Tacz; but it is much larger than that 

 species and, aside from the differences in the shape of the bill (syl- 

 vestris having a bill like that of griseicollis), sylvestris appears always 

 to have the back dark olive-brown, whereas in the adult of S. late- 

 bricola it is deep mouse-gray. 



Specimens examined. — Colombia: Paramo de Chiruqua, 4; Par- 

 amo de Macotama, 2.

 Scytalopus analis Auct. (not of Lafr. = Triptorhinus paradoxus Kittl. ; 

 type examined). 



Range. — Subtropical Zone in Ecuador and Colombia. 



Not uncommon in the denser low growth of the heavy forests of 

 the Subtropical Zone of all three ranges and occasionally extending 

 upward to the lower border of the Temperate Zone and rarely down- 

 ward to the Tropical Zone. All our twenty-four specimens have 

 the flanks, lower abdomen, rump and upper tail-coverts barred with 

 rusty and black. The white crown-patch appears to be a purely in- 

 dividual character not dependent upon age, sex, season or locality. 

 It is well developed in some immature specimens and wanting in 

 others, is present or absent in both sexes, and in specimens from the 

 same locality. Nine specimens possess it to a greater or less degree, 

 fifteen are without it.
