Valparaiso (alt. 4,500-5,500 ft.) Santa Marta Mts., Col., June 9, 1899, G. H. 

 Hull. 



Range. — Subtropical Zone, Santa Marta Mts., Colombia; Andes of 

 Merida, Venezuela. 



Description of Type. — Upperparts deep, neutral gray; forehead and 

 orbital region black; crown with a silvery white patch slightly mixed with 

 gray; rump cinnamon-brown, the feathers terminally barred with black 

 and ochraceous-tawny; upper tail-coverts similar in color but less distinctly 

 barred; tail Prout's brown, more fuscous toward the shaft; wings much 

 like the back, more or less margined externally with the color of the tail; 

 underparts paler than the back, neutral gray, the abdominal region cen- 

 trally whitish; the flanks and under tail-coverts barred with black and 

 bright cinnamon-brown or ochraceous-tawny; feet (skin) brownish; bill 

 black, gonys brownish. Wing, 51; tail, 33; tarsus, 20; culmen, 13 mm. 

 (A second male is without a tail, but, in other respects, including the white 

 crown-patch, agrees with the type.) 



Juvenal Plumage. — With a general resemblance in pattern to the same 

 plumage of S. micropterus, but everywhere paler; upperparts Prout's brown; 

 crown slightly darker; the feathers very narrowly margined with black; 

 loral and ante-orbital region ochraceous-buff ; rump not sharply barred with 

 black and ochraceous-tawny; tail, lacking; wings externally much like the 

 back, the coverts terminally barred with black and ochraceous-tawny; un- 

 derparts rather uniformly barred with ochraceous-buff and black; the bars 

 on the flanks deeper, more transverse, less lunular. (Described from No. 

 97940 American Museum of Natural History, Valparaiso, Col., taken from 

 the nest, June 30, 1899.) 



Postjuvenal Plumage. — Similar to that of the adult but upperparts 

 between Prout's brown and mummy-brown. 



Remarks. — In the light of our large series of this group it appears 

 that the three Santa Marta specimens of Scytalopus referred by 

 Dr. Allen (/. c.) to S. latebricola Bangs, and the one immature speci- 

 men provisionally identified by Bangs, as S. sylvestris Tacz. are 

 representatives of S. micropterus micropterus Scl. 



The presence in both our adult specimens of the white crown- 

 patch, which is often, but not always, found in S. micropterus, and 

 so far as I am aware, in no other species of the genus, betrays the 

 relationships of sanctaz-marta> with the species. Furthermore, the 

 juvenal plumage of sanetw-martos resembles in pattern that of mi- 

 cropterus. It is important to note that both species inhabit the 

 Subtropical Zone. 



Scytalopus latebricolor, on the other hand occupies the Alpine 

 Zone, and is a much larger bird than sanctoe-martce (wing, 63 mm.)
