em form true fuscus. In the northern form the scaly markings come 

 farther down on the breast and sides, and the belly is whitish, not buffy, 

 as in true fuscus. 



Sclerurus albigularis propinquus subsp. nov. 



Type (and only specimen secured on this trip *), from Ghirna, Colombia ; 

 altitude, 7,000 ; No. 6152, $ adult, coll. of E. A. and O. Bangs. Collected 

 Feb. 7, 1899, by W. W. Brown, Jr. 



Subspecific characters. Somewhat intermediate between S. canigularis 

 Ridgw., of Costa Rica, and true S. albigularis of Venezuela, most like the 

 former but with pectoral band paler; throat lighter gray; upper parts 

 duller brown, not chestnut. The new form is also the smallest of the 

 three. 



Color. Back burnt umber with a slight olive cast, head rather more 

 dusky; rump and upper tail-coverts bright chestnut; wings dark brown, 

 primaries, tertials, and secondaries edged with burnt umber; primary 

 coverts dusky-brown ; greater and lesser coverts and scapulars chestnut ; 

 throat smoke-gray ; pectoral band dull ferruginous ; belly and flanks hair- 

 brown, some of the feathers edged and tipped with dull yellowish-fer 

 ruginous ; under tail-coverts chestnut ; tail blackish edged with chestnut ; 

 'iris hazel ; tarsus dusky ; 'f culmen dusky; mandible yellowish toward 

 base, dusky at tip. 



Measurements. Type, adult $ : Wing, 82.6; tail, 56.4; tarsus, 23; ex 

 posed culmen, 21.8. No. 5684, $ adult, from Palomina: Wing, 83; tail, 

 56; tarsus, 23.2; exposed culmen, 21. 



Remarks. The second specimen (the type) of this form secured by Mr. 

 Brown is just like the first, which could not be referred to either S. canigu 

 laris or S. albigularis. $ I therefore no longer hesitate to give it a name.
