Grallaricula boliviana, new species. 



Specific characters. — Most nearly resembling Grallaricula costaricensis, 

 but not closely related to any known species. Throat ochraceous streaked 

 with black, a white breast-patch; lower breast ochraceous, the feathers 

 sharply margined with black, giving a scaled appearance, much as in 

 Preninoplex guttata. 



Type.— No. 137,177, Am. Mus. Nat. Hist., c? ad., Incachaca, 7700 ft., 

 Prov. Cochabamba, Bolivia, May 16, 1915; Miller & Boyle. 



Description of type. — Upper parts between brownish olive and light 

 brownish olive, the crown with darker centers, sides of the forehead basally 

 ochraceous; lores and a narrow eye-ring ochraceous, minutely tipped with 

 black; tail fuscous, the outer feathers externally margined with olive- 

 brown; wings fuscous, externally margined with olive-brown, the inner 

 margins of all but the outer quills ochraceous-buff; under wing-coverts, 

 bend of the wing and outer margin of alula deeper; ear-coverts tinged with 

 cinnamon-brown; throat ochraceous, loosely streaked with black; a narrow 

 white breast-patch; a broad ochraceous band across the lower breast, the 

 feathers sharply bordered with black; flanks more olivaceous, with some 

 buffy feathers obscurely margined with blackish; center of the abdomen 

 white; tibiae brownish olive; lower tail-coverts buffy; feet dark brown; 

 maxilla brownish black; mandible yellowish. Wing 60; tail 28; tarsus 21 ; 

 culmen 12.5 mm. 



Specimens examined. — Grallaricula bolwiana, the type. Grallaricula 

 costaricensis, Costa Rica, 1 ; Veragua, 1 . 



Remarks. — The discovery of this very distinct species introduces a new 

 type of coloration into the genus Grallaricula, and extends the known range 

 of the genus from Ecuador to Bolivia, a distance of approximately 1000 

 miles. Doubtless this gap will in time be filled by the discovery of one 

 or more species of these elusive little birds in Peru. 



Synallaxis stictothorax piurae, new subspecies. 



Subspecific characters. — Similar to Syyiallaxis stictothorax stictothorax 

 Scl., but back more rufescent; wings more widely margined with bright 

 cinnamon-rufous, this color occupying all the outer web of the inner pri- 

 maries and both webs of the secondaries basally; tail almost wholly cin- 

 namon-rufous, the blackish area, which occupies all the inner web of the 

 four central rectricesin stictothorax, reduced to a small, faint, terminal patch. 



Type. — No. 163,085, Am. Mus. Nat. Hist., 9, Chilaco, near Samate on 

 the Rio Chira, Prov. Piura, Peru, May 27, 1919. 



Specimens examined. — Synallaxis stictothorax piurae. Peru: Type 

 locality, 1 d\ 3 9,1?; Samate, Prov. Piura, 1 ?. 



Synallaxis stictothorax stictothorax. Ecuador: Bahia de Caraque, Prov. 

 Manavi, 5; Guayaquil, 4 (topotypes) ; Daule, 1 ; Puna Island, 6; Machala, 1. 



Remarks. — Some specimens of stictothorax stictothorax have the secon- 

 daries basally rufous, but this character is apparently never so highly de- 

 veloped as in piurae. in which the wing, when closed, appears to be almost
