h. AVith a green space on the mantle, or interscapnlary region green with hlne 
margins in adult. 
Larger (wing 215 — 230), the outermost tail-feathers broadly, the next two 
pairs narrowly edged with red. 
A. huruensis Salvad. : Distrib. — Burn. 
h”. Smaller (wing 175); the tail-feathers not edged with rosy, only tipped 
therewith. 
A. sulaensis Rchw. : Distrib. — Sula Islands and Pehng. 
The Sula form of this Parrot was first discovered, either in Sula Mangoli 
or Sula Besi or in both islands, by Mr. Wallace’s assistant, Allen, and 
W allace observed that the Sula birds possessed a reddish bill, whereas in 
those of New Guinea it is black with the base of the upper mandible red. 
Schlegel’s specimens from Sula Mangoli, from the collections of Bernstein and 
Hoedt, did not confirm the validity of the differences pointed out, the three 
first sent to the Leyden Museum all had black bills with some red at the base 
of the upper mandible. The perfect red bill seems to be a sign of maturity. 
The discovery of this handsome species on Peling Island, w'hich is separated 
from Celebes by a strait of less than 20 kilometers, and its absence on the 
mainland (so far as is known) , is a curious circumstance. It is one of those 
facts which have led us to consider as probable the opinion that the Peling and 
Sula groups are the remains of one large island, which has been broken up in 
comparatively recent times. The genus Aprosmictus finds its maximum develop- 
ment in New Guinea, but the eight species recognised by Count Salvadori 
range from Eastern Australia to Peling. 
The Burn form, which probably stands nearest to that of Peling and Sula, 
is larger and has a broad red border on the inner web of the outer tail-feathers. 
Compared with Tanygnathus, Prioniturus and Loriculus, Aprosmictus occupies 
a somewhat remote position; it differs chiefly by its shortened reversed toe, by 
its long, graduated, broad- feathered, blue tail, and by its general coloration of 
red and blue. 
ORDER PICI. 
The Woodpeckers form a part of the heterogeneous group of birds com- 
bined under the term Picariae^ perching-birds which are neither Birds-of-Prey, 
Parrots, Passeres, nor Pigeons. They include the Woodpeckers, Cuckoos, 
Hornbills, Toucans, Trogons, Rollers, Swifts, Humming-birds, King- 
fishers, Bee-eaters, and others. Some of these birds contrast as strongly 
with others as do the long-acknowledged Orders ; for instance, the Woodpeckers
