Panama (topotypical) specimens of perspicillata in their darker crown, more 

 ochraceous (rather than fulvous) lores and orbital region. 

 Baudo (3500 ft.), 4; Barbacoas, 1.

Grallaria perspicillata Lawr., Ann. Lye. N. H. N. Y., VII, 1862, p. 303 (Lion 

 HiU, Panama). 



Evidently occupies the lower Atrato region and eastward into Antio- 

 quia. In its generally paler colors, a specimen from the Rio Salaqui agrees 

 with Panama specimens rather than with periopthalmica. A Puerto Val- 

 divia male has the fulvous markings still paler while its olive-green back 

 is more like that of G. p. lizanoi than of true perspicillata.

(2213a) Grallaricula costaricensis Lawr. 



Grallaricula costaricensis Lawb., Ann. Lyo. N. H., N. Y., VIII, 1867, p. 346 (Bar- 

 ranca, Costa Rica). 



A male from Cocal and a female from San Antonio are more extensively 

 washed with ochraceous below than five of six specimens of costaricensis. 

 The male has the entire underparts ochraceous; the female has the abdomi- 

 nal region white; above they agree in color with costaricensis but they 

 are somewhat larger. Doubtless the west Colombian bird will be found 

 to be separable but this species is so variable in color that I should prefer 

 to see a much larger series before adding to the nimiber of described races. 

 Grallaricula vegeta Bangs, the type of which I .have examined, appears to 

 me to be inseparable from costaricensis. 



Grallaricula flavirostris brevis Nels., of which I have seen the type and 

 three topotypes, has the back more olivaceous, the crown grayer than in 

 costaricensis. This form may be confined to the Subtropical Zone of Mt. 

 Pirri. In the absence of authentic specimens of flavirostris I cannot com- 

 ment on its relationships to that race, but it is apparent that all the speci- 

 mens examined from Costa Rica, Panama, and Colombia, represent but 

 one species. Two specimens from Zaruma, Ecuador, which may be flavi- 

 rostris, are more yellow below than costaricensis and have the maxilla as 

 well as mandible yellow.
