304 ON THE CLASSIFICATION OF BIRDS, Ti 
Tricnociossus, Vigors. (fig. 273.) 2 _ 
Bill compressed : the upper mandible 
much hooked ; the margin without , 
a notch: under mandible length- + 
ened; much longer than deep. 
Wings pointed ; the three first quills WP 
equal ; tertials longer than the secondaries. T ail | 
long, cuneated ; the feathers narrowed throughout. 
T. Swainsonii. Le Vaill. pl. i. pl. 24. Zool. Ill. ii. pl. 92. 
Lorivs, Brisson. Bill as in Trichoglossus. Wings 
pointed. The two first qullls.the longest. Tail — 
moderate, rounded, or graduated ; the feathers broad, 
and hardly narrow at their tips. 
L. garrulus. Z. Ill. ii. pl. 12. Isidorii. Z. Ill. ii. pl. 8. 
Pyrruopes, Sw. Bill and general structure of Lorius. 
Tail cuneated, very long; the feathers narrow and 
pointed ; the two middle pair greatly exceeding the 
others. Indian Islands: representing Palgornis. 
P. papuensis. Le Vaill. i. pl. 77. : 
Suzram. PLATYCERCINE. Loriets. 
Tail long, very broad, considerably cuneated, Bill 
strong, thick, toothed: the culmen very convex. Un- 
der mandible deep, but very short: the gonys curved. 
Feet and toes slender. Tarsus longer than the hallux. 
Vicorsis, Sw.* General structure of Platycercus. 
Orbits naked. Tail lengthened, even, or slightly 
rounded ; the feathers broad throughout. Rasorial. — 
V. vasa. Le Vaill. pl. 81. niger. Le Vaill. pl. 42. — 
Puatycercus, Horsfield and Vigors. Tail cuneated, re- 
fet wish to name this interesting group, of which I only know the typical _ 
/@istinctions, in commemoration of the excellent ornithologist who first de- 
ge fined, and ably illustrated, many of the groups in this family ; and whose 
- efforts towards determining their natural arrangement have been conducted — 
on sound philosophical principles. I have adopted. nearly all the genera 
proposed by Mr. Vigors, simply because I have found them natural. Those ~ 
of M. Wagler I have totally rejected : they are not better than M. Lesson’s, — 
and have therefore no claim to a preference, even on the score of bare | 
priority: they seem to me, in short, highly artificial and altogether inad- 
missible. I suspect that in Végorsia the tail feathers terminate in fine points . 
.,.{although I have not a specimen to refer to), because | view it as the Taso- 
rial type of this circle, representing the Plyctolophine. - |
