Oriolxjs frontalis. (PI. XL.) 



Flavo-aurantiacus ; corona occipitali latissima, alls caudaque ni' 

 gerrimis ; dorso concolore ; remigibus ex toto nigria ; cauda elon- 

 gafa, rectrieibus lateralibus plus minusve Jlavis, mediis duabus 

 ex toto nigris vel puncto apicaliflavo. 



Pure deep yellow, the black on the head leaving only a small 

 frontal spot ; wings entirely black, rarely showing a uiinnte tip or 

 edging of yellow ; yellow on the tail beneath generally less than in 

 O. acrorhynchos, diminishing regularly to the middle feathers, which 

 are wholly black, or in some specimens show a yellow point on the 

 extreme apex of the web ; bill flesh-colour ; feet plumbeous ; iris 

 red. 



In the female the two middle tail-feathers are olivaceous yellow, 

 the tertiaries olive-margined, and the primaries white-edged. A 

 variety of the female occurs with the bill jet-black. 



Length ITS inches ; wing 6 inches ; tail 4| inches. 



Hab. Sula Islands. 



This species is very like 0. acrorhynchos of Manilla, but differs 

 sufficiently in its richer and more uniform colour, longer tail, jet-black 

 wings and middle tail-feathers, and the smallness of the frontal 

 yellow spot. 



Artamus monachus. 



Artamus monachus, Bp. Consp. p. 343, ex Teram.

 lores blackish ; wings and tail ashy lead-colour, primaries blackish

 Celebes, as well as the Sula Islands. 



HiRUNDO JAVANICA. 



Hirundo javanica, Lath. ; Temm. PI. Col. 82. fig. 2. 



I have specimens of this bird from Sumatra, Borneo, Java, and 

 Lombock, as well as the Sula Islands. It agrees well with Tem- 

 minck's figure, and scarcely differs from H. neoxena, Gould, figured in 

 the ' Birds of Australia,' but in being darker on the imder surface, 

 and having a brassy tinge on the wings. 



Hab. Sula Islands and westward to Sumatra. 



Myiagra ptjella. 



C<Brulea; doi'so abdomineque cceruleo-cinereis ; ventre et caudts 



tectricibus inferioribus albis^ cinereo tinctis; alls caudaque 



cinereis, plumis cceruleo marginatis.
