Circe (Circe latirostris), John Gould A very common species, the synonymy of which has much perplexed me: on the Continent it is very generally known by the name of Circe, a term applied to it by M. Bourcier: my friend Saucerotte has also given the name of Schimperi to it in his MSS., an appellation which has unhappily found its way into our scientific lists of Humming-birds; I say unhappily, because both Schimperi and Circe must give place to Swainson’s older name of latirostris; but what could have induced this latter author to place the bird in the genus Cynanthus, I cannot imagine. This illustration has been restored to its original vibrancy by enhancing colors and removing unwanted marks. A monograph of the Trochilidæ, or family of humming-birds was published between 1849 and 1887 by English ornithologist John Gould. This monumental work depicts and describes all the known species of hummingbirds at the time - comprising 418 lithographic plates and information on 537 species."
