DEFINITIONS

LYBIUS
(Lybiidae; Ϯ Black-billed Barbet L. guifsobalito) Gr. λιβυος libuos unidentified bird, possibly allied to the woodpeckers, mentioned by Aristotle and Aristophanes; L. Libya or Libua  Africa; "Libyum novum Avium genus n)   ...   n) Neque minus hæc avis mirum confusarum notarum exemplum est. Rostrum Loxiæ Coccothraustis forma, eadem cum illa durioribus nucibus vivendi ratio, iidem mores; unde Coccothrausti subjunxit BUFFONIUS T. 111. p. 471. Sed rostrum illi serratim incisum margine, quod nulli ex Passeribus competit, nec ea nota alii propior est quam Trogonii, cui & duobus modo digitis anterioribus congruit: at unum tantum posteriorem nacta est, in quo cum Pico tridactylo & Alcedine tridactyla convenit. Guifsobalito, nominis abyssinici partem, avi nomen fecit BUFFONIUS, a clar. Anglo equite BRUCE adlatæ, cui inter Picas sine dubio locandæ, quum latinum quoque genericum nomen invenire æquum sit, placuit Lybius, quæ vox & patriam exprimit & ARISTOTELI jam adhibita est. Facile quoque erit locum in tabula reperire: inter Bucerotem & Trogonem serratirostres aves poni poterit, punctataque linea & cum hoc connecti & cum Pico tridactylo; dein alia ad sinistram excurrat usque ad marginem tabulæ, ubi stellula pingatur, quæ inflexa tabula ostendet locum ubi in opposito latere alia inscribenda erit, cui aliquanto sursum nunc movenda Lox. Coccothraustes respondeat." (Hermann 1783); "Lybius Hermann, Tabl. Affin. Anim., 1783, p. 217, note n. Type, by monotypy, Lybius guifsobalito Hermann." (Peters 1948, VI, 55).
