4, On THE SPECIES OF THE GENUS PRIONITURUS, AND ON THE 
GEOGRAPHICAL DisTRIBUTION OF THE PsITTACIDE IN THE 
Eastern ARCHIPELAGO. By Puintie Lutritey Scuater, 
M.A., SECRETARY TO THE SOCIETY. 
Having lately examined specimens of all the known species of the 
group of Parrots denominated Prioniturus by Wagler, I take the 
opportunity of endeavouring to rectify some errors which have been 
made with regard to their synonymy and geographical distribution. 
Genus Prioniturus, Wagler. 
a. Prioniturus. 
1. PRIONITURUS FLAVICANS. 
Psittacus platurus, Vieill. Nouv. Dict. xxv. p. 314, et Enc. Méth. 
p- 1367 (2). 
Prioniturus flavicans, Cassin, Proc. Ac. Phil. vi. p. 373; Journ. 
Ac. Phil. iii. p. 155(@ ). 
*« Psittacus discosurus, Vieill.”’, Temm. in Mus. Lugd. 
Diagn.— ¢ . Viridis, collo undique cum pectore toto flavicantibus : 
macula verticali ruberrima undique ceruleo circumdata : alis 
extus viridibus fere concoloribus : rectricibus intermediis valde 
elongatis, denudatis, disco terminatis. 
2. Pileo eyanescente: macula verticali nulla: collo undique 
cum pectore flavicantibus : rectricibus intermediis paulo elon- 
gatis, apicibus angustatis, et subdisciformibus. 
Hab. Inins. Celebes, regione Boreali circa lacum Tondano (Forsten 
et Wallace). 
Mus. Lugdunensi ( det 2 ). 
Examples of both sexes of this Parrot are in the Leyden Museum, 
obtained by Forsten at Tondano in Northern Celebes, and marked 
* Psittacus discosurus, Vieill.2 The bird is not Psittacus discurus 
of Vieillot, but possibly, I think I may say probably, his Psittacus 
platurus. However, as this is by no means certain from Vieillot’s 
insufficient description, and as the next species is generally con- 
sidered to be the P. platurus, it is better to adopt for the present 
species the name flavicans, under which Mr. Cassin has accurately 
described the female. Mr. Wallace has lately met with this bird in 
the same locality as that in which Forsten found it. As he truly 
says *, it is “very distinct in both sexes”’ from the P. setarius. 
2. PRIONITURUS SETARIUS. 
Psittacus setarius, Temm. Pl. Col. 15. 
Prioniturus platurus, Wagl. Mon. Psitt. p. 523 (nec Vieill.) ; Bp. 
Consp. Av. p. 6. 
Psittacus spatuliger, mas, Bourj. Perr. t. 53. 
Racket-tailed Parrot, Lath. Gen. Hist. ii. p. 167. pl. 24. 
Prioniturus platurus et P. wallacii, G. R. Gray, List of Psitt. p.17.
