DEFINITIONS

GALLINULA
(Rallidae; Ϯ Common Moorhen G. chloropus) Late Med. L. gallinula  moorhen or waterhen, so named for its cocked tail and halting progress  < L. gallinula  little hen, chicken  < dim. gallina  hen   < gallus  cockerel; "Gallinula. Genus 88.  ...  **1. LA POULE-D'EAU ...  GALLINULA.  ...  Elle est à peu près de la grosseur d'une petite Poule.  ...  On les trouve dans les rivieres & les étangs. Elles font leur nid dans les broussailles qui se trouvent sur leurs bords" (Brisson 1760): based on "Gallinula Chloropus" of Aldrovandus 1599-1603, and many other authors, and Fulica Chloropus Linnaeus, 1758; "Gallinula Brisson, Orn., 1760, 1, p. 50; 6, p. 2. Type, by tautonymy, Gallinula Brisson = Fulica chloropus Linné." (Peters, 1934, II, p. 202).  This genus formerly included Paragallinula, Porphyriops, Porphyriornis and Tribonyx.  
Var. Callinula, Galinula.
Synon. Hydrogallina, Stagnicola.

gallinula
Late Med. L. gallinula  moorhen or waterhen  < L. gallinula  little hen  < dim. gallina  hen  < gallus  cockerel.
● ex “Gallinago minima” of Belon 1555, “Gid,” “Jack-Snipe” or “Judcock” of Ray 1713, and “Petite Beccassine” of Brisson 1760 (syn. Lymnocryptes minima).

nesiotis
Gr. νησιωτης nēsiōtēs  islander  < νησος nēsos  island.
● The Campbell Island Teal is confined to one small island of the Campbell Is. group south of New Zealand. Marchant & Higgins 1990, assumed the name to be a compound of Gr. νησιον nēsion islet, and ωτις ōtis eared (i.e. the island form of Anas chlorotis). No etymology is given in the original description (J. Fleming 1935), and the name could also be construed a compound of the specific combinations Nesonetta aucklandica, Auckland Island Teal, and Elasmonetta chlorotis, Brown Teal, with which species A. nesiotis was directly compared (Anas).
● “The name ‘Island-hen’ given to this bird by the inhabitants of Tristan d’Acunha has suggested to me the specific name nesiotis” (P. Sclater 1861) (‡Porphyriornis).
