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.
