IOLE

(Pycnonotidae; Ϯ Buff-vented Bulbul I. charlottae) Gr. myth. Iole, daughter of King Eurytus of Oechalia and promised in marriage to Hercules. "The following very distinct form among the Flycatchers is also believed to be from the same quarter [Singapore].  Iole, Nobis, n. g.  Allied to Muscipeta, and especially to my M. plumosa (J. A. S. XI, 791), but the beak much less widened, being nearly similar to that of Trichastoma ferruginosum ...  Feet as in Muscipeta, but rather stouter ...  Plumage soft, and excessively dense and copious over the rump; the crown (at least in the species described,) subcrested, with pointed feathers much as in Hypsipetes.  I. olivacea, Nobis." (Blyth 1844); "Species previously listed as I. olivacea, but specific epithet (preoccupied when species included in Hypsipetes) replaced before 1961 and thus permanently invalid" (del Hoyo & Collar 2016).
Var. Jole.
