This well-marked species, although perhaps most like T. niodestus 

 (Cabau.), is very distinct from that bird. The size is much greater, the 

 plumage altogether grayer, and the bars on the tail broader and more 

 sharply defined. Their characters may be more precisely contrasted, as 

 follows : — 



T. modestus.—Wiug, 2.30; tail, 2.25-2.35; bill, from nostril, .40-.45 ; tarsus, .80-.90; 

 middle toe, .52-.58. Above, grayisb-umber, becoming gradually more grayisb 

 on the pileum. Tail cinnamon-umber, with narrow and rather indistinct biirs 

 of blackish less than half as wide as the interspaces. Lower parts bnffy-white, 

 without grayish shade across the juguium ; sides, flanks, and anal region, and 

 crissum deep ochraceous. Hab, — Highlands of Costa Rica. 



T. zeledoni.—\Ymg, 2.50-2.60; tail, 2.1.5-2.45; bill, from nostril, .48-..50 ; tarsus, 1.00; 

 middle toe, .02-65. Above, brownish-slate, more olivaceous posteriorly. Tail gray- 

 ish-brown, with broad and sharply defined bars of blackish, equal in width to the 

 interspaces. Lower parts grayish-white, with a distinct grayish shade across the 

 juguluin ; flanks, anal region, and crissum light grayish-fulvous. iTaft.— Atlantic 

 lowlands of Costa Rica.
