DEFINITIONS

FORPUS
(Psittacidae; Ϯ Green-rumped Parrotlet F. passerinus) Probably arbitrary, but perhaps from Gr. φορεω phoreō  to possess, and πους pous  foot, alluding to the dextrous toes of the parrotlets. Prestwich 1963, suggests an anagram of L. profus  spread out  < profundere  to stretch at full length, with reference to the short, wedge-shaped tail; "Forpus.  Dass durch Aufstellung der Sippe Psittacula das System mit keiner natürlichen Sippe bereichert worden haben bereits andere gefühlt und ausgesprochen. Besser zu einander passen Psittacus passerinus Lin. und rufirostris, denen ich andere, die Mitte zwischen beiden haltende Conurus mit hellgrünem und blauem Gefieder anzureihen geneigt bin. Sie bilden eine der sich überall in der Natur darbietenden Suiten, die unbedenklich als Gruppe gesondert werden können, wenn gleich die sicherlich in der Lebensweise auszeichnenden Eigenthümlichkeiten noch unbekannt geblieben." (Boie 1858, Journal für Ornithologie, 6, 363); "Forpus Boie, Journ. f. Orn., 6, 1858, p. 363. Type, by subsequent designation, Psittacus passerinus Linné. (Hellmayr, Field Mus. Nat. Hist. Publ., Zool. Ser., 12, 1929, p. 446, note 2.)   ...   Replaces Psittacula Illiger 1811 not of Cuvier 1800" (Peters, 1937, III, p. 202).
