We now arrive at the fifth or fissirostral division 
of the Psittacidce, which, by Mr Swainson, has been 
designated by the name of Platycercina (Broad- tail), 
the members of the genus Platycercus of Vigors 
and Horsfield being considered as its typical repre- 
sentatives. Of the other groups whicli belong to 
this section, we only venture to speak noth diffi- 
dence, not having had an opportunity, as well from 
want of time as of materials, to make that strict 
analysis of the species which is required to trace out 
with certainty the true affinities, and exact station 
of each. We have sufficient data, however, to be- 
lieve, that the ground Parrakeets (gen. Pezoporus, 
Illig.), the beautiful miniature Maccaw-looking spe- 
cies belonging to the genus Nanodes, Vigors, the 
two species composing Wagler’s genus Nymphicus, 
represented by the Psitt. sisetis and Psitt. Nova 
Hollandia of authors, and some other forms, among 
which, perhaps, the Psittacus Platurus of Tem- 
minck's “ Planches Colories” may be included, en- 
ter into it. Those interesting species which inhabit 
Madagascar, and known by the name of Vasas, viz. 
Psilt. niger and Psitt. mascarinus, Linn., forming 
Wagler’s genus Coracopsis, also shew a decided affi- 
nity in form and habit to the true Platycerci, and 
there is little doubt belong to the division. To the 
genus Palao’rnis, Vigors, which we have placed 
among the Macrocercina, or Maccaw section, an
