The Parrots have been arranged under many named subdivisions, the limits of which are mostly arbitrary, though several very natural groups are tolerably distinct. First, among the species with square tails, we may notice the great Black Cockatoos of Australia (Calyptoryncfms, Vig.), large crested species, with beak of extraordinary strength, and very deep vertically. Their plumage is black, with some red or yellow on the tail; wings capable of vigorous flight; and food the seeds of the Eucalypti, \\\Va the juice of which fruit their bills are generally stained. Attempts to maintain them in captivity appear to have always hitherto failed. The subdivision Con/don, Wagleri, is barely separable. The White Cockatoos (Plyctolophui, Vieillot), the species of which inhabit the Indian Archipelago and Australia, fall into two minor groups according to the form of the crest. Their disposition is sin- gularly gentle and affectionate, and several species are abundantly brought alive to Europe, where they are kept with much facility. Their singular antics and extraordinary grotesque movements are well known to all. The square-tailed species without crests constitute th'e restricted Parrots (Psittacus) of several authors, and are found in the old and new continents. They are generally esteemed for the facility with which they learn to speak ; and the majority are gaily coloured : it is neces- sary, however, to subdivide them much further. One group, termed Nestor, is remarkable for the extraordinary elongation of the upper mandible, which far overhangs the lower : it is believed to be employed in hooking up bulbs: the members of this division are essentially crestless Cockatoos, allied to PL nasicus, and are also natives of Aus- tralia. The Love-birds (Psitfacula, Kuhl), compose a beautiful
