DEFINITIONS

SYNALLAXIS
(Furnariidae; Ϯ Rufous-capped Spinetail S. ruficapilla)  Gr. συναλλαξις sunallaxis, συναλλαξεως sunallaxeōs  exchange; perhaps given because Vieillot thought the two species may represent the two sexes of a single species, or an allusion to their characters warranting generic separation.  Reichenbach 1853, complained that Synallaxis, of feminine gender, contained the Latin masculine noun axis  axle, and wondered what scientists were to make of it!; "SYNALLAXE, Synallaxis.   Bec grêle, entier, pointu; mandibule supérieure un peu arquée, l'inférieure droit; narines couvertes de plumes à leur base; ailes courtes, arrondies." (Vieillot 1818); "SYNALLAXE, Synallaxis. Genre de l'ordre des Oiseaux SYLVAINS et de la famille des GRIMPEREAUX   ...   La SYNALLAXE A QUEUE ROUSSE, Synallaxis ruficauda, Vieill., a été apportée du Brésil.   ...   La SYNALLAXE A TÊTE ROUSSE, Synallaxis ruficapilla, Vieill., se trouve au Brésil.   ...   Les différences qu'on remarque entre cet oiseau et le précédent, ne caractérisent-elles pas les sexes?" (Vieillot 1819); "Synallaxis Vieillot, Nouv. Sict. Hist. Nat., 24, 1818, p. 117. Generic characters only; species added op. cit., 32, 1819, p. 310. Type, by subsequent designation, Synallaxis ruficapilla Vieillot (G. R. Gray, List Gen. Bds., 1840, p. 17)." (Peters 1951, VII, 80).
