DORIFERA VERAGUENSIS, Salvin. Veraguan Lance-bill. Dorifera veraquensis, Salvin, Proc. Zool. Soe. 1867, p. 154. Hemistephania veraguensis, Elliot, Synopsis of the Humming-Birds, p. 82 (1878). Tue very dark shade of the green under-surface, coupled with the metallic green forehead, which is darker than in D. ludovici@, serves to render this species recognizable from the last-named bird. It was described by Mr. Osbert Salvin from Veraguan skins collected by Enrique Arce ; and I have a skin in my collection said to be from Costa Rica; but there may be some doubt as to the correctness of this locality. Mr. Salvin published the followwing remarks when first calling attention to the distinctness of the Veraguan bird :—‘‘ There seems to be considerable individual variation between members of this species ; or I should be inclined to separate, as a distinct race, the bird found in Veragua, a single specimen only of which has as yet reached me. The shining forehead is considerably darker and of a bluer shade, the bill longer, and the under plumage blacker than in a New Granadian specimen of D. ludovicie before me ; the wings, too, are shorter. Should the receipt of additional specimens confirm the constancy of these distinctions, I propose for this race the name of Dorifera veraguensis.” The Plate represents two males and a female bird, drawn from specimens lent to me by Messrs. Salvin and Godman.
