Oreopyra castaneiventris, Lawrence, Ann. Lye. New York, ix. p. 124 (1868, part.). 



Mr. Elliot states that this species is closely allied to 0. leucaspk, but is distinguished by its ashy white 

 tail ; the under tail-coverts are also paler and the bill is longer (culmen i inch). 



The female resembles that of 0. leucaspis, but has the bill longer than in that species. 



It appears to be confined to Costa Rica, 



The figures in the Plate represent two males and a female of the size of life.

This s|)eeies has already heen figured in the Monograph — the male as 0. leucaspis, the female as 

 A, castanewentns. It has been thought better to take advantage of the opportmiity of re-figuring it 

 along with the other two species of the genus. 



Like 0. cinereicauda^ it has a white throat, but may be easily distinguished from that species by its 

 black tail. 



At present it is only known from Panama, where it has been found on the Volcan de Chiriqui, 



In Costa Rica O. cinereicauda takes its place.
