It is just possible that Mr. Gould’s Anthocephala castaneiventris 
may be the female of this species ; and the presence of a specimen of 
that species agreeing with Mr. Gould’s examples from Chiriqui, shot 
in the same locality as the bird now described, lends some colour to 
the supposition. In Mr. Gould’s collection are three specimens of 
his A. castaneiventris, which, through his kindness, I have had an 
opportunity of examining; one of these has the shining crown so 
characteristic of the males of the genus Oreopyra, to which I refer 
the present bird. Mr. Gould’s figure represents both male and 
female (vol. iii. pl. eciii), and I am inclined to think he has judged 
rightly. Observing the sexes of O. hemileuca, analogy would sug- 
gest that the female of O. calolema is without the shining head, and 
that the under surface is a dull brownish grey. I have not hesitated 
to describe this bird as above ; for, should the surmise prove correct, 
the name castaneiventris is totally inapplicable. 
All hitherto known of the genus Oreopyra was the existence of a 
single specimen, in Mr. Gould’s collection, of O. Jewcaspis, upon which 
the genus was founded. It was one of Warszewicz’s discoveries in 
the Volcano of Chiriqui. The present collection makes known two 
additional species of the same form; and I have no hesitation in 
placing in the group the bird, from the same locality, doubtfully
