1870.] MR. 0. SALVIN ON THE BIRDS OF VERAGUA. 195 
Myrmotherula menetriesi. 
Calovevora; Chitra; Bugaba; V. de Chiriqui. 
The undetermined species, no. 93 of my previous list, is, I think, 
a female of this species, which is the only member of the genus 
Arcé has yet sent us from Veragua. Mr. Lawrence enumerates 
four species of this genus as found in Costa Rica, two of which I 
have nut yet seen; the two others are also found at Panama, and 
may therefore belong to Veragua, but have hitherto escaped notice. 
I may also mention that we possess a skin collected by Carmiol in 
Costa Rica, which does not differ from these Veraguan birds, to 
which we have applied the above name.

Bugaba. 
Agrees with Panama specimens. The species is also found in 
Costa Rica (Lawr. Ann. Lye. N. Y. ix. p. 109).

Bugaba. 
This species is also found in Costa Rica (Lawr. J. c.). Arcé’s speci- 
mens agree with others from Panama, whence the types were 
obtained.

Mina de Chorcha; Bugaba. 
Specimens, including examples of both sexes, from the district of 
Chiriqui, agree with Panama skins of the true G. nudiceps, Cassin. 
A little further north, in Costa Rica, the race Sclater and I described 
as G. chiroleuca is found, which extends onwards into Honduras.

Bugaba. 
This bird seems to be much more abundant at Panama than fur- 
ther to the northward, as no additional specimens have been obtained 
in Costa Rica since the original examples were sent to Berlin by 
Dr. Hoffmann.
