Diagn.— ¢. Viridis; torque angusto cervicali postico auran- 
tiaco: macula verticali antice roseo-rubra, postice plaga 
cinerea terminata: alis fascia lata grisea, secundarias occu- 
pante, bipartitis, axillis cyanescentibus : rectricibus interme- 
diis valde elongatis, denudatis, disco terminatis.

Mr. Wallace obtained specimens of both sexes of this Parrot near 
Macassar in Southern Celebes, and has also lately met with it again 
in Northern Celebes, near the Lake of Tondano, though more sparingly 
than P. flavicans. I have examined Temminck’s type in the Leyden 
Museum, and I can see no difference between that and Mr. Wallace’s 
birds. 
This species may be distinguished from the former at the first glance 
(1) by its narrow and distinct hind neck-collar, that in P. flavicans 
being broad and extending all round the neck and over the body 
below ; (2) by its rosy head-spot, bordered behind by a broad greyish 
blotch, the head-spot in P. favicans being rosy, and situated in the 
middle of a bluish blotch ; (3) by the blue shoultlers and pale greyish 
band formed by the secondaries, the wings in P. flavicans being 
uniform green ; (4) by the elongated under tail-coverts, those of P. 
flavicans being comparatively short.

The British Museum contains specimens of two nearly allied, but 
probably distinct species of this section of the genus Prioniturus, both 
from the Philippines. They are distinguished in Mr. Gray’s Cata- 
logue as P. discurus and P. spatuliger. But as the latter specific 
appellation was used by Bourjot St.-Hilaire for a compound species 
formed by the union of P. setarius and P. discurus, it is a useless 
synonym. It follows, therefore, that whichever of the two Philippine 
species is different from that in the Paris Museum, which is the type 
of Vieillot’s and B. St.-Hilaire’s figures, will require a new name. 
I take this opportunity also of exhibiting a Table illustrative of the 
present condition of our knowledge of the distribution of the Psitta- 
cide in the Eastern Archipelago, which I have drawn up at the re- 
quest of Mr. A. R. Wallace. In the Indian Region, which includes 
the great islands of Sumatra, Java, and Borneo, and extends over 
the Philippines, the generic types of this family are few. Paleornis 
and Loriculus are the most prominent. Psittinus consists of a single 
species found in Malacca, Sumatra, and Borneo: and Cyclopsitta,
