Show 1870.] MR. o. SALVIN O N T H E BIRDS O F VERAGUA. 205 on the Panama Railway and in Costa Rica, the northern limit of range. 131. PHAETHORNIS LONGIROSTRIS (Delatt.); Gould, Mon. Troch. i. t. 19, Intr. p. 42. Bugaba. Two specimens of this common Central-American species have at last been obtained by Arce. The bird seems also to be rare in Costa Rica, from which country I have received specimens since I wrote the note on P. emiliee (P. Z. S. 1867, p. 152). Phaethornis emiliee. Calovevora ; Boqueti de Chitra; Cordillera del Chucu. 132. CAMPYLOPTERUS HEMILEUCURUS (Licht.); Gould, Mon. Troch. t. 45, Intr. p. 52. Calovevora; Chitra ; Cordillera del Chucu. By no means an uncommon species in Veragua. The specimens sent by Arce differ in no way from Guatemalan and Mexican examples. Phceochroa cuvieri (Delatt. et Bourc.) ; Gould, Mon. Troch. t. Intr. p. 55. Bugaba. A single specimen only. The bird is common on the Panama Railway- 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 calolcema. Calovevora ; Cordillera del Chucu ; V. de Chiriqui. Oreopyra leucaspis. V. de Chiriqui. On reaching the volcano of Chiriqui, the locality whence Warsze-wiez obtained the original specimen of this species, Arce procured an interesting series of skins of it. He writes me word that the females are like the females of Oreopyra calolcema, and have the breast cinnamon. Ii this view is correct, we should have three species with females very closely resembling one another, viz. O. leucaspis, O. ci-nereicauda, and O. calolcema ; and then the true O. castaneiventris (Anthocephnla 1 castaneiventris, Gould) will in all probability be the female of O. leucaspis. A close examination of a number of specimens of the so-called O. castaneiventris shows that Chiriqui specimens are of a brighter green above, and have the uropygium coloured uniformly with the back. In districts where 0. calolcema 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- PROC. ZOOL.
