In addition to the species described, the following 
belong to this present genus, viz. Plydolophus Philip- 
pinarum, Red-crested Cockatoo, a native of the Phi- 
lippine Islands; Plyct. Moluccensis, Wag., the Great 
red-crested Cockatoo, which is found in the Mo- 
luccas, Sumatra, 8cc. ; Plyct. cristata, Wag., also a 
native of the Moluccas, and the Plyct. rosei-capil- 
lus, Vieill. (Psittacus Eos. of Kuhl), which, how- 
ever, departs from the type in the form and struc- 
ture of the crest, approaching in this respect nearer 
to Wagler’s genus Licmetis, which is represented by 
the Psittacus nasicus of Temminck, described in the 
1 3th volume of the Transactions of the Linnaean 
Society, and in the “Planches Coloriees,” plate 351. 
Nearly allied to the Cockatoos, and included in 
that genus by many authors, is the Red-crowned 
Parrot ( Psittacus galeatus of Latham, Kuhl, &c.) 
It forms the type of Wagler’s genus Corydon, and, 
according to the views of that author, forms the con- 
necting medium between the Cockatoos and the ge- 
nus Calyptorynchus of Vigors and Horsfield, upon 
which we are about to enter,' and for which group 
we propose to give the title of Geringore, taken from 
the name applied to one of the finest and largest 
species by the natives of Australia. The characters 
of the genus Calyptorynchus are: — Bill thick, 
very strong, much higher than long, wide at the 
base, compressed towards the culmen, greatly arch-
