Abstract	Psittaciform birds from the Middle Eocene of Messel (Hessen, Germany) and from the Lower Eocene London Clay of Walton-on-the-Naze (Essex, England) are described (Psittacopes lepidus n. g., n. sp. and three unnamed species). These birds resemble the Recent Family Psittacidae in the morphology of the tarsometatarsus, but exhibit distinct differences in other skeletal elements, especially in the rather coly-like beak and in the wing skeleton. For the first time the presence of the QuercypsittidaeMourer-Chauviré 1992 in the Lower Eocene London Clay is demonstrated; this family differs distinctly from the four taxa mentioned above. Since new material ofPalaeopsittacus georgei Harrison 1982 from the type locality shows that this bird was anisodactyl (and therefore not a member of the Psittaciformes), the Quercypsittidae only contain the genusQuercypsitta Mourer-Chauviré 1992.Es werden psittaciforme Vögel aus dem Mittel-Eozän von Messel (Hessen, Deutschland) und aus dem Unter-Eozän des London Clay von Walton-on-the-Naze (Essex, England) beschrieben (Psittacopes lepidus n. g., n. sp. und drei unbenannte Arten). Diese Vögel ähneln der rezenten Familie Psittacidae im Bau des Tarsometatarsus, zeigen aber deutliche Unterschiede in anderen Skelettelementen, besonders im eher mausvogelähnlichen Schnabel und im Flügelskelett. Die QuercypsittidaeMourer-Chauviré 1992 werden erstmals aus dem Unter-Eozän des London Clay nachgewiesen; diese Familie unterscheidet sich deutlich von den oben erwähnten vier Taxa. Da neues Material vonPalaeopsittacus georgei Harrison 1982 aus der Typus-Lokalität zeigt, daß dieser Vogel anisodactyl war (und damit kein Vertreter der Psittaciformes), beinhalten die Quercypsittidae nur die GattungQuercypsitta Mourer-Chauviré 1992.
