OREOPTEA. 333 



Though 0. leucaspis has a very restricted range, confined to the Volcano of Chiriqui 

 and the higher hills in its vicinity, it appears to be a very common bird in its own 

 home. Arce sent us a large series of skins including fully adult birds and young in 

 all stages of advancing maturity. It appears firom the latter that the young males are 

 not like the females in their first plumage, but resemble the older birds, the white 

 throat and glittering head being assumed gradually. In some birds purple feathers 

 appear at the edge of the white throat and even in the middle of it, and thus show 

 the close relationship 0. leucaspis bears to 0. calolcema, in which the whole throat is 

 reddish purple.

R(A. Costa Rica {Garcia ^ \ Carmiol% Navarro {B<mcard^). 



This species was described by Mr. Lawrence firom a specimen sent him from Costa 

 Rica by Mr. A. C. Garcia ^, but the exact place where it was procured was not recorded. 

 All the specimens we have received are in the same condition, and the only precise 

 recorded locality where the species occurs is Navarro, where M. Boucard obtained a 

 single specimen in May ^. Judging from what we find in 0. lewcaspis, 0. cinereicauda is 

 probably restricted to the forests of some of the higher mountains of Costa Rica in the 

 vicinity of San Jose, the capital. 



As a species 0. dnereicavda is quite distinct firom 0. lettcaspis, though the two birds 

 resemble each other in many respects. The females are probably not separable with 

 certainty, and that sex of 0. calolcema is almost exactly similar. The bird we beUeve 

 to be a female of 0. cinereicauda has a longer bill than the others, and we place it 

 under this name on that account.
