This is a somewhat larger-sized bird than the D. hidovlcia;, with a slightly longer 

 bill. There is no difi"erence in the color of the plumage, and I doubt very much, 

 should the locality be unknown, whether the two birds could always be distin- 

 guished. It may be regarded as a race, but hardly as a distinct species. Total 

 length, 5 in. Wing, 2^ in. Tail, 1^ in. Culmen, l^^g in.
