(Strigidae; Ϯ Forest Owlet H. blewitti) Gr. ἑτερος heteros  different, strange; γλαυξ glaux, γλαυκος glaukos  owl; "Heteroglaux, Gen. Nov.   Size, medium; head, small; disc, imperfect; nostrils, medium sized, pierced well inside the margin, of a moderately developed cere; external orifice of ear, smaller than eyes, circular, without operculum, mouth of internal orifice, crescentic.  Wings short, with short wing ends, first four primaries very conspicuously notched on the inner webs, 4th primary longest, 3rd intermediate between 4th and 5th, 2nd intermediate between 5th and 6th, 1st equal to 8th; tarsi, stout, short, equal to mid toe without claw, densely covered with silky feathers; upper surfaces of toes, thickly covered with stiff bristly-shafted feathers, inner toe longer than outer.   This very peculiar form of owl which I cannot identify with any known genus, though it approaches Surnia, Dum; Athene, Boie; and Ieraglaux, Kaup, was obtained by my friend Mr. F. R. Blewitt in the dense forests of the eastern portion of the Central Provinces, on the borders of the Tributary Mehals. At first sight it would certainly be classed as an Athene; but the head is much smaller than in any of the Athene's I possess   ...   Heteroglaux Blewitti, Sp. Nov." (Hume 1873); "Heteroglaux Anonymous = Hume, Stray Feath., 1, 1873, p. 467. Type, by monotypy, Heteroglaux blewitti Hume." (Peters 1940, IV, 147). The Forest Owlet was believed extinct, but rediscovered in Maharashtra, India, in 1997.
