DEFINITIONS

MYRMOTHERULA
(Thamnophilidae; Ϯ Pygmy Antwren M. brachyura) Dim. < genus Myrmothera Vieillot, 1816, antpitta; "GENUS II. MYRMOTHERULA.  Cauda brevis; sæpe brevissima: rectricibus plerumque duodecim, interdum decem: rostrum tenue, subulatum, non magis altum quam latum: acrotarsiis et paratarsiis divisis.  In M. pygmæa and the next following species of this genus the tail is very diminutive, and the tail-feathers are much narrowed. In the latter part of the series it is longer and more broadly feathered, but never so elongated as in true Formicivora. The general facies of these two genera is otherwise nearly the same.   1.

● "Sporophila intermedia Cabanis  ...  Loxia grisea Gmelin (Syst. Nat., 1, [2], p. 857, 1789) was long used for the above species. The name rests exclusively upon "Le Gros-Bec de Virginie" Daubenton, Pl. Enl., pl. 393, fig. 1, called by Buffon "Le Grisalbin." The rather poor figure shows a blackish bill, white throat, and whitish superciliaries, and I am inclined to agree with Chubb (Bull. Brit. Orn. Cl., 41, p. 35, 1920) that the name is better dropped as undeterminable." (Hellmayr 1938, XIII, 176) (unident.).
