DEFINITIONS

HYLIA
(Scotocercidae; Ϯ Green Hylia H. prasina) Gr. ὑληεις hulēeis  dwelling in the woods  <  ὑλη hulē  woodland, forest; "Genus HYLIA, nobis.  Small, in general appearance sylviform.  Bill curved, upper mandible thick or wide on the lateral view, compressed towards the end, carinated, nostril in a large membrane.  Wings moderate, first quill spurious, third and fourth longest and nearly equal, tail rather long, legs moderate, tarsus with about four large scales in front, toes slender, claws rather large.  Type Sylvia prasina, Cassin.    63. HYLIA PRASINA, (Cassin.)  Sylvia prasina, Cassin, Proc. Acad. Philada. 1845, p. 325. "Stiphrornis superciliaris, Temm. Mus. Lugd."?   This bird is by no manner of means a Stiphrornis, if S. erythrothorax is the type, which appears to be the case, nor is it a Chloropeta of which C. natalensis, Smith, is the type, nor moreover do we know any other genus to which it belongs, and so set up for ourselves as best we may." (Cassin 1859); "Hylia Cassin, 1859, Proc. Acad. Nat. Sci. Philadelphia, p. 40.  Type, by original designation, Sylvia prasina Cassin." (Traylor in Peters, 1986, XI, p. 221).  The Green Hylia and the Tit Hylia Pholidornis were formerly treated in a separate family Hyliidae, a proposal recently resurrected.
