DEFINITIONS

STELGIDILLAS
(Pycnonotidae; Ϯ Slender-billed Greenbul S. gracilirostris) Gr. στελγις stelgis, στελγιδος stelgidos  strigil, scraper; ιλλας illas, ιλλαδος illados  thrush; “STELGIDILLAS, ² new genus.   Chars. gen.—Genus generi "Chlorocichla" dicto simile, sed maxillæ tomii parte subterminali distincte serrata; nec corpore subtus clare flavescente.  Type.—Andropadus gracilirostris Strickland.  The uncertainty which has attended the determination of the proper generic affinities of Andropadus gracilirostris has led to the placing of this species in three different genera, with the characters of none of which does it sufficiently agree.  From Criniger it may be at once distinguished by the depressed and slender bill—the maxilla with serrations on the cutting edge just posterior to the subterminal notch.  The narrow, depressed bill separates it easily from either Andropadus or Eurillas, while from Chlorocichla, to which it seems to be most closely allied, it differs in the presence of serrations on the distal portion of the maxillar tomium.  All the known species of Chlorocichla, moreover, are yellow or yellowish olive below, and the genus, as restricted by Captain Shelley, is a well-defined group.  The species described by Cabanis as Andropadus gracilis is not perfectly typical, but should apparently be associated generically with gracilirostris.   ...   ² στελγις, strigilis; ιλλας, turdus.” (Oberholser 1899).
