DEFINITIONS

ESTRILDA
(Estrildidae; Ϯ Common Waxbill E. astrild) Specific name Loxia astrild Linnaeus, 1758. It has been suggested that the name derives from a German or Dutch avicultural term for a waxbill. However, an incandescent Reichenbach 1849, wrote that the name Estrelda, from astrild, was neither Latin nor English, nor anything else, and castigated the linguistically proficient authors who foisted it on the scientific community (“Der Name Estrelda, aus Astrild gemacht, ist weder lateinisch noch englisch, noch sonst etwas; man könnte ihn kaum deutsch-englisch nennen und muss erstauen, wie ein paar sprachkundige Männer ihn in die wissenschaft aufzunehmen vorsuchten”); "ESTRILDA.   Rostrum breve, conicum, immarginatum.  Alæ breves, rotundatæ; remige 1^ma spuria, minuta, 3^tia, 4^ta, et 5^ta æqualibus, longissimis.  Cauda subelongata, gradata.  ... Type. Loxia astrild. Linn.  This, and the preceding genus [Amadina], appear strictly confined to the warm regions of the old world; and will detach a vast number of species from the Loxiæ and Fringillæ of Linnæus. I have endeavoured in vain to reconcile the different groups of these birds proposed by Brisson, Cuvier, and Vieillot, with any thing like a geographic or a natural arrangement; and this must be my apology for not adopting either their names or characters; the first would lead to much confusion, while the latter are artificial. The minute spurious quill, (which I have termed, for the sake of uniformity, the first), seems to be an unerring indication of an African or Asiatic origin; and I find the same character in all those I have seen from New Holland." (Swainson 1827); "Estrilda Swainson, Zool. Journ. iii, p. 349, 1827.  Type by original designation, Loxia astrild Linn." (W. Sclater, 1930, Syst. Av. Aethiop., II, p. 794).   
Var. Astrilda, Estrelda, Estrila.

Black-tailed Waxbill (incana)
SCI Name: Estrilda perreini incana
INCANA
(Cisticolidae; Ϯ Socotra Warbler I. incana) Specific name Cisticola incana P. Sclater & Hartlaub, 1881; "Cisticola incana Scl. & Hartl., P. Z. S. 1881, p. 166, pl. 15.  TYPE in British Mus., "♂ coll. by Prof. Balfour, 23 March 1880, on Sokotra Is."; imm. ♂, wing 50, tail 44: examined and judged to be, not a Cisticola, but more like a Franklinia, probably best classified as the Type of:- Incana incana genus nov., defined thus:-  Form.  Near Franklinia, viz. bill long, very straight, slender and much compressed apically; feet rather large; wings short, obtuse, weak (the foregoing copied from the orig. descr. in P. Z. S. 1881, to which add); texture of plumage loose and soft, particularly dense and puffy on lower back and rump; but tail Cisticoline, less steeply graduated than Franklinia, and rectrices not so narrow (twelve in no., as in both sp.).   Coloration (Only Summer and juvenile dresses known) Plain brownish grey above and white below; more like Franklinia than any species of Cisticola, except tail which is of Cisticoline spotted fan pattern above and below, with white tips and outermost edgings, that of the male Summer dress also with conspicuous white mirrors.  Habits (according to description). Much more like Franklinia than Cisticola." (Lynes 1930).
