Material examined. A male and a female from Ramphastos brevicarinatus, Barro Colorado Island, Panama Canal Zone, collected by Mr J. Van Tyne of the University of Michigan, through whose kindness I have been enabled to examine them. The species was originally described from “probably Ramphastos tocard” (which is R. brevicarinatus) from Colombia. My material agrees with the original description and is probably correctly identified, although, as will be further considered, another species of the same genus occurs upon toucans.
