LEPTODON
(Accipitridae; Ϯ Grey-headed Kite L. cayanensis) Gr. λεπτος leptos  fine, slender; οδων odōn, οδοντος odontos  tooth; "Leptodon n.g. (F. cayanensis et palliatus Auct. A Recent. sub genere Cymindi, nimis diverso, enumerati ¹))  ...  ¹) Char. Rostrum compressum lateribus planis; longit, dimidii capitis, sutura tota æqve arcuata, dente ante medium parvo. - Nares membrana tectæ, antice rima transversa apertæ, (in Cymindi rima infera, longitudinalis).  Pedes spongioso-incrassati, reticulati, digitis subtus planis" (Sundevall 1836); "Leptodon¹ Sundevall, Vetensk.-Akad. Handl. for 1835, p. 114, 1836—type, by monotypy, "Falco cayanensis et palliatus auct."   ...   ¹ It has been claimed that Leptodon was previously used by Rafinesque for some genus of mollusks, but such is not the case.  Rafinesque (Ann. Gén. Sci. Phys., 5, p. 295, Sept., 1820) created for the species Unio leptodon the subgenus Leptodea, which, of course, does not prevent the further use of Sundevall's term for the Cayenne Kite.  It appears that nobody except Sherborn (Ind. Anim., sect. sec., p. 3500), who gives the correct spelling of Rafinesque's name, ever consulted the original reference.  Authors evidently relied on Scudder (Nomencl. Zool., Supplem. List, p. 185, 1882), in whose work the name is misquoted as "Leptodon."" (Hellmayr & Conover 1949, XIII, 22).
