Grallaria lizanoi, Cherrie, Pr. U. 8. Nat. Mus. xiv. p. 3427. 
G. perspicillate similis, sed dorso saturate cinereo pileo concolore, striis rhachidalibus dorsi paucis et tenuis- 
simis, striis corporis subtus latis: rostro nigro, mandibule basi pallida, pedibus pallide plumbeis. 
Long. tota 5:0, ale 3-1, caude 1-2, rostri a rictu 1-0, tarsi 1-4. (Descr. maris exempl. typ. ex Trojas,

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. ézanoi is probably restricted to the low- 
lands of the Pacific side of the mountains of Costa Rica. 
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. izanoi with regard to G. perspicillata is hardly established.

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 Rica, where it occurs 
on the eastern side of the Cordillera.
