Two specimens of this common Central-American species have at 
last been obtained by Arcé. The bird seems also to be rare in Costa 
Rica, from which country I have received specimens since I wrote 
the note on P. emilie (P. Z. 8. 1867, p. 152).

By no means. an uncommon species in Veragua. The specimens 
sent. by Areé differ in no way from Guatemalan and Mexican 
examples.

A single specimen only. The bird is common on the Panama Rail- 
way-line and about the eastern shores of the gulf of Nicoya in Costa 
Rica. In Guatemala this species is replaced by P. roberti, which, 
however, is only found in the forest-region of northern Vera Paz. 
Oreopyra calolema.

Oreopyra leucaspis. 
V. de Chiriqui. 
On reaching the voleano of Chiriqui, the locality whence Warsze- 
wiez obtained the original specimen of this species, Arcé procured 
an interesting series of skins of it. He writes me word that the fe- 
males are like the females of Oreopyra calolema, and have the breast 
cinnamon. If this view is correct, we should have three species with 
females very closely resembling one another, viz. O. /eucaspis, O. ci- 
nereicauda, and O. calolema; and then the true O. castaneiventris 
(Anthocephnla? castaneiventris, Gould) will in all probability be the 
female of O. leucaspis. A close examination of a number of speci- 
mens of the so-called O. castaneiventris shows that Chiriqui speci- 
mens are of a brighter green above, and have the uropygium coloured 
uniformly with the back. In districts where O. calolema alone occurs, 
Specimens of the so-called O. castaneiventris have the back of a duller 
green, and the uropygium tinged with bluish; the bill, too, appears 
to be somewhat shorter. So far as our present knowledge extends, 
the geographical distribution of the three species is as follows :— 
Oreopyra leucaspis is restricted to the volcano of Chiriqui, O. cine-
