New York, ix. p. 124 (1868, part.). Mr. Elliot states that this species is closely allied to 0. leucaspis, but is distinguished by its ashy white tail; the under tail-coverts are also paler and the bill is longer (culmen 7/8 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. [R. B. S.]
