Above brownish -slate, becoming more olivaceous on the rump, upper 

 tail-coverts, and tail. liemiges with very indistinct (scarcely observable) 

 darker bars. Tail heavily but somewhat irregularly barred with dusky 

 black, the black bars about as wide as the interspaces. A sharply defined 

 and conspicuous superciliary stripe of white; a wide stripe of brownish- 

 slate ("like the crown) along upper half of the auriculars. Chin, throat, 

 cheeks, and lower parts iu general grayish- white, with a faint grayish 

 washacross the jugulum, more distinct on the sides of the breast. Flanks, 

 anal region, and crissum light fulvous. Lining of the wing grayish- 

 white. [Type in Mus. K. R.] 



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

 (Caban.), 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.— Wing, 2.30 ; tail, 2.25-2.35 ; bill, from nostril, .40-.45 ; tarsus, .80-.90 ; 

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

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

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

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

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



T. zeiedoni.—\Ymg, 2.50-2.(i0; tail, 2.1.5-2.45; bill, from nostril, .48-.50 ; tarsus, 1.00; 

 middle toe, .62-65. 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 

 jugulum ; flanks, anal region, and crissum light grayish-fulvous. Hah. — Atlantic 

 lowlands of Costa Rica. 



2.— PSEUDOCOLAPTES LAWRENCII (Ridgway, MS.). 



Sp. ch.— Wing, 4.15-4.35; tail, 4.15-4.30; bill, from nostril, .50 ; tar- 

 sus, 1.00-1.05; middle toe, .6S-.70. Primaries, primary-coverts, greater 

 and middle wing-coverts brownish-black, the first more brownish ; both 

 rows of wing-coverts tipped with bright ochraceous. Tufts on sides of 

 neck creamy buff. 



Adult: Pileum, nape, and auriculars brownish-black, streaked with 

 rusty-fulvous ; nape more conspicuously streaked with light fulvous or 

 bilfif ; a narrow superciliary streak of buff. Back, scapulars, lesser wing- 

 coverts, and tertials ferrugiueous, the feathers of the back very indis- 

 tinctly bordered terminally with dusky. Kump, upper tail-coverts, and 

 tail bright brick-rufous, immaculate. Chin, throat, and sides of the 

 neck creamy-buff, the latter deepest, and immaculate; the throat faintly 

 barred with dusky ; jugulum and breast light buff", the feathers bordered 

 with dusky, producing a conspicuously striped appearance — the dusky 

 prevailing laterally, the buff medially ; middle of the abdomen plain 

 deep buff. Sides and flanks ferrugiueous, considerably lighter than the 

 back ; crissum plain rusty -ochraceous. Bill blackish, the gonys whit- 

 ish. Feet horn-color (greenish-olive in life). Iris dark brown.
