DEFINITIONS

GAMPSONYX
(Accipitridae; Ϯ Pearl Kite G. swainsonii) Gr. γαμψονυξ gampsonux,  γαμψονυχος gampsonukhos  hooked-claw, an epithet of the vulture  < γαμψος gampsos  curved; ονυξ onux, ονυχος onukhos  claw; "This bird decidedly belongs to the Accipitrine subfamily of the Falconidæ  ...  It possesses the bill of the Hawks, and also the shortness of wing which so strongly characterizes them; but the structure of the wing itself is the same as in Falco, the second quill feather being the longest, and the first and second of these feathers being marked on the inner web by an abrupt emargination near the apex; while the tarsi also display the character of the same group in having the acrotarsia reticulated  ...  the bird before us, although a New World species, I shall invest with an Old World name. GAMPSONYX.  Rostrum breve; mandibulis integris; naribus rotundatis.  Alæ breves; remige secunda longissima, tertia secundæ fere æquali; primæ et secundæ pogonio interno fortiter prope apicem emarginato.  Cauda mediocris, æqualis.  Pedes mediocres; tarsis reticulatis, acrotarsiis infra genu usque ad medium plumatis.   SWAINSONII.  ...  Dⁿⁱ Swainson, naturæ indagatoris seduli, acutississimi, felicissimi, hæc avis, ab illo primum detecta, merito nomen ferat."
