Q supra mari similis, sed dilutior ; capite summo dorso concolore: subtus cinnamomea; cauda ad basin viridi, 
rectricibus lateralibus albido terminatis, fascia lata subterminali chalybeo-nigra. (Descr. maris et femine

Eastern Costa Rica and thence southwards to the higher mountains of Western 
Panama are the homes of this species, which was discovered by Arcé on the slopes of 
the Volcan de Cartago!. The same collector subsequently obtained us a good series of 
specimens from various points in the mountains of Western Panama. According to 
M. Boucard this species is only met with in the forest 9°. | 
4. Oreopyra pectoralis.

O. caloleme similis, sed pectore (a fronte adspecto) nigro nec micanti-viridi distinguenda. (Descr. exempl. 
typ. ex Costa Rica. Mus. nostr.) 
Hab. Costa Rica (Endres 2). 
A single male in our collection and others in that of Gould, all apparently prepared 
by Endres, are all that we have seen of this species, which differs from the ordinary 
form in having a black instead of a glittering green breast. Though the types are 
marked as coming from Costa Rica, we have as yet no clue to which district the 
species belongs. . 
The female of this bird is probably undistinguishable from that sex of O. calolema. 
The female specimens we associate with the males of 0. pectoralis are made up by the 
same collector in a precisely similar way. 
b®, Pileus dorsum concolor. 
DELATTRIA. 
Delattria, Bonaparte, Consp. Av. i. p. 70; Salv. Cat. Birds Brit. Mus. xvi. p. 308. 
This genus, which was first separated by Bonaparte, has frequently been united to 
Ceeligena, with which it has several characters in common, but the bill is straighter and 
the lateral rectrices are of nearly uniform colour, and without the conspicuous white 
tips which distinguish Celigena clemencie. Delattria has also a close affinity to 
Oreopyra, but the style of coloration is different and none of the species have the 
glittering crown possessed by all the members of the latter genus.
