DEFINITIONS

EMARGINATA
(Muscicapidae; † Sickle-winged Chat E. sinuata) L. emarginatus  emarginated  < emarginare  to provide with a margin; "Sickle-winged Chat  ...  Tip of P9 greatly attenuated, in some specimens forming sickle 1 mm wide and 10 mm long" (Keith et al. 1992); "SAXICOLIDÆ.  Genus I. EMARGINATA.  Emarginata, gen. nov. . . . .Type. E. sinuata." (Shelley 1896); "Emarginata Shelley, Bds. Afr. i, p.89, 1896.  Type by original designation, Luscinia sinuata Sund." (W. Sclater, 1839, Syst. Av. Aethiop., II, p. 459).  Sharpe 1903, remarked that Emarginata was an adjective, and could not be employed in a generic sense.  Such conservatism led to a proliferation of replacement names during the nineteenth century by authors like Illiger, Cabanis, and Sharpe.
Synon. Karrucincla, Phoenicuroides, Poliocichla, Psammocincla.
