The Brazilian genus Cephalepis comprises two species, with lengthened ornamental crests terminating in a single plume, on which account they stand alone not only in their own family, but, so far as I am aware, among birds generally. The females are entirely devoid of this conspicuous character. I think it very probable that additional species of this form will be discovered when the natural productions of the interior of Brazil become better known.
