1885,] DURING THE VOYAGE OF THE YACHT ' MARCHESA.' 251 



fauna would probably show a preponderance of western rather than 

 eastern species. 



In the following list I have given in full the Philippine localities, 

 and also the occurrence in Borneo and Celebes, of each species, 

 together with such notes on the habits of the birds as my limited 

 residence on the islands permitted me to make. Where the extreme- 

 length measurements of the different species are given, they are in 

 all cases taken from the birds while in the flesh. The wing-mea- 

 surements only are from the dry skin.

None of the above birds appear to be immature, at least so far as 

 regards plumage, neither does there seem to be any sexual difference. 

 The feathers of the crest are all strongly tinged with lemon-yellow 

 at the base, but the reddish-orange colour which, on the under tail- 

 coverts, gives its specific name to the bird, is on the crest invariably 

 confined to one solitary feather. In some skins the ear-coverts are 

 strongly washed with orange-yellow. Length 32*5-330 centims. ; 

 wing 2 1 "2-21 '8; no difference between S and J. Iris pinkish 

 red ; brown in the young bird. Bill bluish. Tarsus blue-grey. 



This bird is exceedingly common on the island of Sulu, where 

 it seems generally to occur in small flocks of three or four indi- 

 viduals. It is often to be seen in a state of captivity among the 

 natives, and one individual was brought alive to Europe in the yacht 

 ' Marchesa,' and presented to the Zoological Society by Mr. Kettle- 

 well in 1884 '. The flesh of this species is good eating, and free 

 from the bitterness so characteristic of many of the Parrots. 



2. Prioniturus discurus (Vieillot). 



Psittacus discurus, Vieillot, Gal. des Ois. i. p. 7, pi. 26. 



Prioniturus discurus, Wald. Tr. Z. S. ix. p. 132 ; Sharpe, Tr.

Hab. Luzon {Meyer, Everett) ; Negros (>S^feere) ; Zehu {Everett); 

 Panaon {Everett); Mindanao {Cuming, Everett, Murray) ; Basilan 

 {Steere) ; Sulu {Burbidge) ; Balabac {Steere) ; Guimaras {Meyer). 



It is j)robable that this species is not common in Sulu Island, for 

 during a residence there of more than six weeks I never obtained a 

 single specimen, and oidy once saw it.
