ON THE CLASSIFICATION OF BIBOS. 
Tbichoglossus, Vigors, {fig- 273.) 
Bill compressed : the upper mandible 
much hooked ; the margin without 
a notch : under mandible length- 
ened ; much longer than deep. 
Wings pointed j the three first quills 
equal ; tertials longer than tlie secondaries. Tail 
long, cuneated ; the feathers narrowed throughout. 
T. Swainsonii. Le Vaill. pi. i. pi. 24. Zool. 111. ii. pi. 92. 
Lobius, Brisson. Bill as in Trichoglossus. Wings 
pointed. The two first quills the longest. Tail 
moderate, rounded, or graduated ; the feathers broad, 
and hardly narrow at their tips. 
L. garrulus. Z. 111. ii. pi. 12. Isidorii. Z. HI. ii. pi. 8. 
PvBBiioDES, 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 Patesornis. 
P. papuensis. Le Vaill. i. pi. 77. 
SuBFAM. PLATYCERCINiE. 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. 
ViGORSiA, Sw.* General structure of Platyce.rcns. 
Orbits naked. 'Fail lengthened, even, or slightly 
rounded ; the feathers broad throughout. Rasorial.

• I wish to name this interesting group, of which I only know the typical 
distinctions, in commemoration of the exccileiit ornithologist who first de- 
fined, and ably illiistralcd, many of the groups in this family ; and whose 
efforts towards determining their tialuralarrangement have been conducted 
on sound philosmihical principles. J have adopted nearly ail 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 Iherefore no claim to a preference, even on the score of bare 
priority : they seem to rne, in short, highly artificial and altogetlicr inad- 
missible. I suspect that in Vigorsia the tail feat hers terminate in fine points 
(althoufli 1 have not a specimen to tefer to), because 1 view It as the laso- 
rial type of this circle, rcpreseiiting the PU/deiophina.
