DEFINITIONS

EURILLAS
(Pycnonotidae; Ϯ Little Greenbul E. virens) Gr. ευρυς eurus  broad, wide; ιλλας illas, ιλλαδος illados  thrush. In ornithology illas refers to an assortment of unrelated, supposedly thrush-like birds. Oberholser, here quoted, frequently used the term for bulbul; "EURILLAS, ¹ new genus.  Chars. gen.—Genus generi "Andropadus" dicto simile, a quo differt rostro latiore et depressiore, naribus rotundatis.  Type.—Andropadus virens Cassin.  The type of the genus Andropadus is A. importunus (Vieillot), from which A. virens differs so much in structural characters that its generic separation seems necessary.  The very much broader, more depressed bill, oval instead of slit-like nostrils, are very distinctive.  The tomia are scarcely or not at all incurved, and the closed bill is thus without the groove which is so conspicuous along the commissure of Andropadus importunus.  The outline of the culmen is nearly straight until near the tip, while in Andropadus it is curved almost from the base.  The rictal bristles are also more strongly developed in Eurillas.  From other related genera, except Stelgidillas, Eurillas may easily be distinguished by the serrations of the subterminal portion of the cutting edge of the maxilla, and from Stelgidillas by the short, broad, and much-depressed bill.   ...   ¹ Eυρυς, latus; ιλλας, turdus." (Oberholser 1899); "Eurillas Oberholser, 1899, Proc. U. S. Nat. Mus., 22, p. 15.  Type, by original designation, Andropadus virens Cassin." (Rand in Peters, 1960, IX, p. 225).
