DEFINITIONS

CHLOROSPINGUS
(Passerellidae; Ϯ Common Bush-tanager C. flavopectus ophthalmicus) Gr. χλωρος khlōros  green; σπιγγος spingos a form of σπινος spinos, probably identical to σπιζα spiza a finch (< σπιζω spizō  to chirp) commonly eaten at Athens, and identified by most authors as the Chaffinch, but the names could just as well have applied to any small bird. In ornithology the epithets spingos and spiza used in combination are not confined to the finches (Fringillidae), but used indiscriminately for an assortment of finch-billed or finch-like birds (e.g. Ploceidae, Thraupidae, Emberizidae, Passerellidae, Cardinalidae, Drepanididae). The Common Bush-tanager, Chlorospingus or Bushfinch and its congeners were formerly treated as tanagers Thraupidae; "Gen. CHLOROSPINGUS nov. gen *)  Grün-Ruderfink.   719. 1. Ch. leucophrys Nob. —  **)  Tanagra leucophrys Licht. in Mus. Berol.   ...   *) Von χλωρος, grünlich und σπιγγος  nom. prop. — In der Bildung der Flügel und des Schwanzes ist die Gruppe der vorhergehenden [Hemispingus] noch sehr ähnlich, der Schnabel hingegen ist stärker, kürzer, höher und daher dem Typus von Pipilo annähernd ähnlich, nur schwächer als in dieser Gattung, welche grössere Formen aufweist und von welcher sich Chlorospingus ausserdem durch nicht abgerundete Flügel und Schwanz wesentlich unterscheidet.    **)  ...  Die folgenden, uns nicht genügend bekannten Arten scheinen der hier beschriebenen sehr ähnlich zu sein:  1.
