Goldman, of the Biological Survey, U. S. Department of Agriculture, has been detailed to the Smithsonian Biological Survey of the Panama Canal Zone to collect mammals and birds in the Canal Zone and adjacent parts of Panama. The most interesting discovery in his work to date has been a hummingbird representing a beautiful new genus and species. The type came from the higher slopes of the Cerro Azul   ...   GOLDMANIA, new genus.  Type Goldmania violiceps, new species.  Genus named in honor of Mr. E. A. Goldman.  Generic characters.— In general appearance similar to Saucerottea, but under-tail coverts small and very short; the three median ones remarkably specialized, being very narrow at base, broad and strongly decurved distally and very stiff; tenth, or outermost primary, shorter than ninth and abruptly attenuate near tip in adult male; bill longer than head, terete, narrow, slightly expanded basally and nasal operculum overlapping edge of mandible; feathers on tarsus very short, leaving inner side completely exposed.   GOLDMANIA VIOLICEPS, new species  ...  collected by E.
