DEFINITIONS

MERGANETTA
(Anatidae; Ϯ Chilean Torrent Duck M. armata) Genus Mergus Linnaeus, 1758, merganser; Gr. νηττα nētta  duck; "In many of its characters it approaches the Ducks (Anatidæ), but in others it evinced an affinity to the Mergansers (Mergus), especially in its long and stiff tail-feathers, and narrow and pointed beak. It differs, however, from either of the groups mentioned in having, in both sexes, a strong spur on the wing. Mr. Gould proposed for this new bird the name Merganetta armata.   Genus MERGANETTA.  Rostrum haud minus longum quam caput, rectum; fere cylindraceum, ungue apicali distincto, incurvato, at minus abrupte quam in genere Mergus dicto.  Mandibula superior lamelloso-dentata, vel tornio crasso carneo, intus profunde serrato, instructa; naribus linearibus fere centralibus.  Alæ mediocres primariis secundo et tertio longissimis; humeris calcare valido et acuto armatis.  Cauda, ut in mergo, rigida.  Tarsi aliquanto elongati, squamis hexagonis ad latera obtecti, et antice scutellis. Digiti palmati, medio quam tarsus paululum longiore; halluce libero, alte posito, et paululum lobato.  MERGANETTA ARMATA. " (Gould 1842); "Merganetta Gould, Proc. Zoöl. Soc. London, 1841 (1842), p. 95. Type, by monotypy, Merganetta armata Gould." (Peters 1931, I, 188).  Recent work indicates that this currently monospecific genus should again be split into three separate species (i.e. M. armata, M. colombiana, M. leucogenis).
Var. Marganetta.
Synon. Raphipterus.
