Muscitrea Blyth, J. A. S. B., xvi, p. 121 (1843). Type, Tephrodornis grisola Blyth, 1843.
The genus Muscitrea is one which it has been very difficult to place, in part owing to the plumage of the young bird not being known. Mr. B. B. Osmaston has now shown (Journal Bombay Nat. Hist. Soc. xvii, p. 159) that the young is at no stage spotted or squamated, characteristics which at once prevent it being placed either in the Muscicapidae or the Pericrocotidae (Campephagidae). As the young is paler, but brighter, than the adult, it appears best suited by its other characters to a place in this family, though even in this it is somewhat aberrant.
In Muscitrea the sexes are alike. The bill for a Warbler is. exceptionally strong, deep and is much compressed laterally; there are three strong rictal bristles and there are numerous supplementary hairs which overhang the nostrils; the wing is long and the first primary large, exceeding in length half the second; the tail is square.
