HISTORY OF THE PARROTS. 
satisfactorily resolve. In addition to the true Maccaws, 
the typical form of this subfamily, it appears natu- 
rally to embrace many of the other American long- 
tailed species, now divided into separate generic 
groups (except by Wagler, who retains the whole 
under the single genius Sittace), one of which has 
been characterized under the title of Psittacarc, 
Vigors, answering nearly to the Peruclie-Aras of 
the French ornithologists, the members of which are 
distinguished by having the orbits and face to a 
greater or leB8 extent naked, as exhibited in the spe- 
cies selected for illustration. Another is composed 
of the species in which those parts are feathered, and 
for which the title of Aratinga has been proposed, 
though it is probable that a still further generic sub- 
division of this latter group will be required. In 
this division, also, we would place the long-tailed 
Parrots of the ancient world, forming the genus Pa- 
Iceornis, Vigors, a group whose history and distri- 
bution he has traced with such acumen and classic 
lore in the pages of the Zoological Journal. With 
this group we shall commence our illustrations, as it 
is through one of its members, the Palccornis Barra- 
bandi, Vigors, that a connexion appears to be sup- 
ported with the Platycercine or broad-tailed division, 
which stands at the further extremity of the circle of 
the Psittacidce. This bird, with the tail and general 
character of Palaornis, exhibiting a near approach 
in the proportions of its legs and feet to the genus 
Plritycercus, Vigors, of whose region or metropolis
