G. guatemalensi quoque similis, sed omnino obscurior et, preter rostrum robustum, minor ; capite summo fere 
nigro, plumarum marginibus nigris latioribus: subtus saturate ferruginea: rostro longiore, robustiore. 
Long. tota 7°2, ale 4:3, caude 1°6, rostri a rictu 1°3, tarsil*85. (Descr. exempl. ex Calovevora, Panama.

Hab. Costa Rica, Irazu (Rogers), Turrialba (Zeledon®); Panama, Volcan de Chiriqui 4, 
Calovevora*, Santa Fé+ (Arcé). 
Though the bill is somewhat stouter, this is a small dark form of G. guatemalensis 
found in Costa Rica and the State of Panama, another still smaller allied form 
(G. regulus) occurring in Guiana, Colombia, and Ecuador. 
G. princeps was discovered by our collector Arcé, who sent us several specimens from 
the State of Panama. It was subsequently found in Costa Rica, whence we have also 
an example and where Mr. Zeledon has met with it.

Hab. Panama, Volcan de Chiriqui®, Mina de Chorcha®, Santa Fé +, Santiago de Vera- 
euas 4 (Arcé), Lion Hill (M‘Leannan 12%). 
This Grailaria was one of M‘Leannan’s discoveries during his residence on the 
Isthmus of Panama. Mr. Lawrence described his first specimens in 18611, and the 
bird has since been traced as far as the district of Chiriqui®. Other records of it are 
given in Costa Rica and Nicaragua, but the birds there referred to doubtless belong— 
the former to G. intermedia and the latter to G. dives. | 
The olive-brown back, with its fawn-coloured elongated shaft-stripes, render this 
species distinct from all its southern allies and from the closely affined Central- 
American birds which follow. 
M‘Leannan says G. perspiciliata is not common on the Isthmus of Panama, where it 
it is to be observed in the dense woods and jungle, leading a solitary life on the 
ground ”.
