(Psittacidae; Ϯ Red-breasted Parakeet P. alexandri) Mod. L. psittacula  little parrot, parakeet  < dim. L. psittacus  parrot  < Gr. ψιττακος psittakos  parrot; "Perruches ...... Psittacula." (Cuvier 1800); "As an item of importance to extra-limital workers, I might notice that Opinion No. 39 legitimatises Cuvier's Psittacula, and this is quite different to the genus now so called and is antecedent to Palæornis. Thus Psittacula Cuvier was provided for Les Perruches, and as examples in the Leçons are cited P. alexandri and P. rufirostris. These, as understood by Cuvier, were congeneric and are typical Palæornis of Vigors. I have already indicated that Conurus Kuhl was typified by Lesson by Palæornis and should displace it. At the present time Psittacula Cuvier will replace Conurus, while Palæornis must altogether disappear.  Apparently for the South American Parrots now termed Psittacula, Boie's genus name Forpus will come into use" (Mathews 1917).
