Birds observed in the Island of Negros. 103 



An example sent does not differ from Indian and Ceylon in- 

 dividuals. By INIontbeillard^s title it appears that the type came 

 from the Philippines. 



DiCRURUs MiRABiLis, sp. n. (Plate V.) 



Lower breast, abdominal region, flanks, and under tail-coverts 

 pure vv^hite. Remainder of plumage black, with glossy green 

 reflections. Tail but slightly forked. Bill black. Wing 5*5 ; 

 tail, outer rectrix 5"37, middle pair 5; bill from forehead 

 1-18, from gape 1'37; hallux 0*50; tarsus 0-87. 



From a single example, sex not noted. Island of Negros, 

 " Eyes black (?), feet and legs black. High in the mountain 

 forests. Stomach, insects. Usually in pairs ; scarce, only saw 

 them one day." The colour here given of the irides requires 

 confirmation. 



This species belongs to the group of which D. halicassius 

 (Linn.) is the type, and the members of which are principally 

 Papuan, In the shallow bifurcation of the tail it comes 

 nearest to D. halicassius. No other species of this genus as 

 restricted displays any white in the plumage, beyond the usual 

 white markings of the under wing-coverts, found more or less 

 to prevail throughout the Dicruridce. Its analogue in Buchanga 

 is B. fingah (Linn.) .
