518 NEW BIRDS FROM LOWER AMAZON. 



2. Thryophilus teeuioptera, sp. no v. 



Sp. char.— Similar to T. leucotis (Lafr.), but larger (!), darker, 

 browner (?), and with auriculars distinctly streaked with dusky. 



Habitat. — Lower Amazon (Diamantina). 



Adult male (Diamantina, Lower Amazon, June 29, 1887 ; C. B. Eiker) : 

 Above light bister-brown, becoming more rufescent on wings, rump, 

 upper tail-coverts, and tail, especially the latter, which inclines to tawny 

 brown or russet ; back narrowly but rather distinctly barred with dusky ; 

 greater wing-coverts narrowly barred with dusky, and remiges much 

 more broadly and distinctly barred with same, the bars broader and 

 blacker on secondaries ; tail crossed by about ten broad bars or narrow 

 bands of black, these growing gradually broader towards end of tail, 

 where they are about equal in width to the tawny interspaces, or about 

 .10 wide; uppertailcoverts very faintly (hardly perceptibly) barred with 

 deeper brown. A narrow but very distinct superciliary stripe of white, 

 margined above by a narrow blackish line ; a broad post-ocular streak 

 of the same color as pileum ; sides of head otherwise grayish white, the 

 auriculars distinctly streaked with dusky ; chin and throat plain white ; 

 sides of neck similar to hind-neck, etc., but more grayish. Lower parts 

 (except chin and throat) dull buffy, fading into dull whitish on middle 

 of breast and belly, tinged with grayish on sides, and deepening into 

 light brown on flanks ; the under tail-coverts pale tawny brown. Upper 

 mandible black, edged with paler ; lower mandible dull whitish, tinged 

 with dusky terminal ; legs and feet dusky. Length (skin) 4.90; wing 

 2.65, tail 2, exposed culmeu .05, bill from nostril .45, depth at base .17, 

 tarsus .90. 



Another specimen (same locality, June 27, sex not determined) is 

 similar in color to the type, except that the lower parts are slightly 

 darker. Length (skin) 4.80 ; wing 2.45, tail 1.80, exposed culmeu .63, 

 bill from nostrils .45, tarsus .82. 



This species agrees pretty well in its characters with Mr. Sharpe's de- 

 scription of T. leucotis (Lafr.), in Vol. VI of the British Museum Cat-- 

 alogue of Birds, p. 207. but whether of the same species or not it certainly 

 is not the Thriothorus leucotis of Lafresnaye (Rev. Zool. 1845, 338). 



The most nearly related species with which I have been able to com- 

 pare it is T. galbraithi (Lawr.) from the Isthmus of Panama, from which 

 the new species differs in decidedly darker, though otherwise similar, 

 color of pileum, hind neck, back, and scapulars; barred back; black 

 line along upper margin of superciliary stripe ; conspicuously streaked 

 ear coverts; much less fulvous sides and flanks; decidedly larger bill, 

 and other characters. 



3. Cyphorhinus griseolateralis, sp. nov. 



Sp. char.— Nearest G. salrini Sharpe,* but much grayer; posterior 

 portion of sui)erciliary stripe white; sides of neck dull ash-gray; mid- 



* Cyphorhinus salvini Shaupk, Cat. B.. Brit. Mas. VI, 1881, 292, pi. 18, fig. 1 (Rio 

 Napo, eastern Ecuador).
