Mr. Ridgway has kindly sent us the type of this Grallaria, which was recently 

 described by Mr. Cherrie. It is most nearly allied to G. perspicillata of Panama, 

 having striated flanks like that bird and not plain fulvous ones like G. intermedia, 

 though it has the dark grey back of the latter bird, in that respect differing from 

 G. perspicillata. 



According to Mr. Cherrie, the range of G. lizanoi is probably restricted to the low- 

 lands of the Pacific side of the mountains of Costa Eica. 



Chiriqui specimens of G. perspicillata are somewhat intermediate between the typical 

 Panama birds and G. lizanoi. The fawn-coloured shaft-stripes of the feathers of the 

 back are narrow, and the whole back is slightly greyer. The ultimate status, there- 

 fore, of G. lizanoi with regard to G. perspicillata is hardly established, 



6. Grallaria intermedia,

In many respects this bird is intermediate between G. perspicillata and G. dives, 

 having the spotted wing-coverts, the rictal stripe, and the striped chest of the former, 

 and the unspotted grey back and rufous flanks of the latter. These characters, we 

 think, render it quite distinct, and we consider Mr. Ridgway was right in separating 

 it specifically. Its range would appear to be confined to Costa Eica, where it occurs 

 on the eastern side of the Cordillera.
