1863.] MR. A. R. WALLACE ON THE BIRDS OF BOURU. 29 



the various islands that it is impossible to separate birds which other- 

 wise agree exactly in form and coloration. A. papuensis, Bp. Consp. 

 p. 344, will have to be considered as a very slight local variety of 

 the present bird. 



HiRUNDO JAVANICA. 



Hirundo javanica, Lath., Temm. PI. Col. 83. f. 2. 

 Hub. Bouru and the islands westward. 



MyIAGRA GALE ATA. 



Myiagra galeata, G. R. Gray, P. Z. S. 1860, p. 352. 



Hab. Bouru and the Moluccas. 



Remarks. — The only two specimens procured are ashy above, with 

 faint signs of glossy blue and rufous white beneath ; they probably 

 show the immature plumage of the species, of which I have speci- 

 mens from Ceram and the small islands east of it, and also from 

 Morty, north of Gilolo. 



Monarcha loricata. (PI. VI.) 



Nigro-chalybea, subtus alba ; mento gulaque squamatis, nigro' 

 chalybeis ; cauda alba, rectricibus mediis nigris, duabus utrin- 

 quejuxta medium nigro terminatis ; rostro pedihusque cceruleo- 

 plumbeis. 



Blue-black ; beneath pure white, except the throat, which is 

 covered with scaly feathers of a rich metallic blue-black ; this colour 

 meets the black of the upper parts at the angle of the mouth, and 

 extends in an oval shield to the bottom of the neck ; under wing- 

 coverts white ; tail with the three lateral feathers on each side en- 

 tirely white, the next two black-tipped, and the middle pair entirely 

 black, with occasionally some white touches on the outer webs ; 

 bill and feet lead-blue ; iris dark. 



The sexes are alike ; in the young bird the white is replaced by 

 pale reddish brown, and the black by fuscous brown. 



Total length 7 inches ; wing 3|^ inches. 



Hab. Bouru Islands (Moluccas). 



Remarks. — This beautiful species is nearly allied to M. leueura of 

 Mr. G. R. Gray, which I sent from the Ke Islands, east of Ceram. 



Rhipidura tricolor.

Rhipidura bouruensis. 



Fusco-plumbea ; capite nigro, ventre pallide rufo, alts caudaque 

 fuscis ; gula albeseente, pectoris maculis elongatis albis ; stria 

 supraoculari occulta, alba ; tectricibus majoribus pallide ter- 

 minatis, remigibus ultimis pallide marginatis; rectricum duarum
