DEFINITIONS

ARUNDINAX
(Acrocephalidae; † Thick-billed Warbler A. aedon) L. arundo, arundinis  reed; Gr. αναξ anax, ανακτος anaktos  master, ruler; "Arundinax, nobis.  This genus was first detected by Mr Jerdon, among a number of specimens of Calamoherpe arundinacea (?), which the only species as yet ascertained a good deal resembles, on a superficial view.  ...  Its true affinity, however, is with Sphenura and its allies, and not with the preceding group.  The bill is somewhat more produced and tapering, slenderer and less laterally compressed, than in Sphenura, with barely discernible emargination of the upper mandible, and the rictal bristles are smaller and more slightly curved; rest as in Sphenura, but the tail-feathers narrow and much graduated.    Ar. olivaceus, nobis.  General aspect of Calamoherpe arundinacea (?), but at once distinguished by its shorter and thicker bill, and much more graduated tail-feathers." (Blyth 1845); "Arundinax Blyth, 1845, Journal Asiatic Soc. Bengal, XIV (II), no. 164, p. 595.  Type, by monotypy, Arundinax olivaceus Blyth, 1845 = Muscicapa aedon Pallas, 1776." (JAJ 2020).
Var. Araudinax.
Synon. Phragamaticola.

Aedon
L. aëdon, aëdonis  nightingale  < Gr. αηδων aēdōn, αηδονος aēdonos  nightingale, songstress  < αειδω aeidō  to sing.  In Gr. myth. Aëdon, wife to Zethus, was changed into a nightingale when, in attempting to murder the eldest son of her fecund sister Niobe, she killed her own son Itylus.  In other versions of the legend she was metamorphosed into a goldfinch.  The ICZN has banned the use of diacritic marks in scientific names, but in transliteration the Gr. aëdon should be so spelled, the diaeresis indicating that the second of the two vowels be pronounced separately.  Similarly, amongst other examples, the ubiquitous Gr. combining form -oïdēs.  Unhappily, whereas the removal of the German umlaut (ü) is compensated for by the addition of an e after the modified vowel, the removal of the diaeresis, a useful guide to pronunciation, leaves no trace of its passing.
• (Muscicapidae; syn. Cercotrichas † Rufous-tailed Scrub Robin C. galactotes) "VI. Fam.  Sylviadae Vigors.   ...   Aedon: Sylvia galactodes Temminck u.a." (Boie 1826). "Aedon Boie, 1826, Isis von Oken, col. 972. Type, by monotypy, "Sylvia galactodes Temminck" = Sylvia galactotes Temminck. Not Aedon T. Forster, 1817." (JAJ 2019).  This is the Rufous Bush Chat of an earlier generation of British birdwatchers.
• (Muscicapidae; syn. Luscinia † Thrush Nightingale L. luscinia) "101. SYLVIA LVSCINIA.  Luscinia Aedon?   ...   101. AEDON LVSCINIA.  NIGHTINGALE." (T. Forster 1817); "Aedon Forster, 1817, Synop. Cat. Brit. Birds, pp. 14; 53. Type, by monotypy, Aedon luscinia Forster = Motacilla luscinia Linnaeus." (Ripley in Peters, 1964, X, p. 32).
• I have yet to locate or verify Aedon of Vieillot, referred to by Bonaparte, 1850, Conspectus, I (1), p. 286: "599. Ædon, Boie 1826. nec Vieill.".
