(Psittacidae; Ϯ Australian King Parrot A. scapularis) Alister William Mathews (1907-1985) son of Australian ornithologist and author of this name Gregory Mathews; "Genus CXC. Aprosmictus Gould, Proc. Zool. Soc. Lond., 1842, p. 111 replaces Ptistes Gould, Handbook Birds Austr. ii. p. 37, 1865.   Genus CXCI. Alisterus nom. nov. replaces Aprosmictus Gould, 1865, not 1842.   When Gould introduced his genus Aprosmictus he stated "Types Platycercus scapulatus and erythropterus." When Gray, in the Cat. Gen. Birds, 1855, designated types he selected the latter, and of course against this there can be no objection. However, in 1865 Gould proposed a new name for the erythropterus group, and restricted Aprosmictus to the scapulatus group. This misuse of the names was carefully nated by Gray in the Handl. Gen. Sp. Birds B. M. 1870   ...   As Gray's action settled the matter, there is no other course open save the introduction of a new name for the group erroneously known by the generic name of Aprosmictus and the use of Aprosmictus for the genus hitherto known as Ptistes.  The type of Alicterus is A. cyanopygius = Psittacus cyanopygius Vieillot." (Mathews 1911); "Alisterus Mathews, Nov. Zool., 18, 1911, p. 13. New name to replace Aprosmictus Gould 1865 not of Gould 1843. Type, by original designation, Psittacus cyanopygius Vieillot = Psittacus scapularis Lichtenstein." (Peters 1937, III, 248).
