OREOPYRA. 333 
Though 0. deucaspis 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. Arcé sent us a large series of skins including fully adult birds and young in 
all stages of advancing maturity. It appears from 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 O. leucaspis bears to O. calolema, in which the whole throat is 
reddish purple.

O. leucaspi similis, sed rostro forsan longiore, capite summo ceeruleo tincto et cauda grisea ad apicem obscuriore 
nec chalybeo-nigro distinguenda. (Descr. maris ex Costa Rica. Mus. nostr.) 
Hab. Costa Rica (Garcia! *, Carmiol®), Navarro (Boucard *). 
This species was described by Mr. Lawrence from 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 O. leucaspis, O. cinereicauda is 
probably restricted to the forests of some of the higher mountains of Costa Rica in the 
vicinity of San José, the capital. 
As a species 0. cinereicauda is quite distinct from O. lewcaspis, though the two birds 
resemble each other in many respects. The females are probably not separable with 
certainty, and that sex of O. calolema is almost exactly similar. The bird we believe 
to be a female of O. cinereicauda has a longer bill than the others, and we place it 
under this name on that account.
