120 ON BIEDS EECEXTLT OBSEEVED OR OBTAINED [1872. 



from this Xcgros individual in having six white outer rectrices, and in having the under wing- 

 coverts white centred with black. These characteristics have been verified by an examination of 

 a considerable series of Malayan-peninsular and Javan specimens. As is well known, Indian, 

 Cingalese, and Burmese examples have the under wing-covcrts pure white, and possess eight 

 white rectrices. 



The oldest title for the Malayan and Javan Copsychus appears to be Lanius musicus, Raffles, 

 I'r. Linn. Soc. xiii. p. 307 (1S22), given to the Sumatran species, which in all probability will be 

 found to agree with the Malayan and Javan. 



In many individuals of C. saularis the fourth pair of rectrices, and in C. musicus the third 

 pair, are more or less brown or black.

title it appears that the type came from the Philippines. 



DiCRUKUS siiR,\BiLis, sp. n. (Plate V. in orig.) 



Lower breast, abdominal region, flanks, and under tail-coverts pure Avhite. Remainder of 

 plumage black, with glossy green reflections. Tail but slightly forked. Bill black. AYing 5 '5 ; 

 tail, outer rectrix 5"37, middle pair 5 ; bill from forehead I'lS, from gape 1"37 ; hallux 0"50; 

 tarsus 0-87. 



From a single example, sex not noted. Island of Xegros. " 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. hulicussins (Linn.) is the type, and the 

 members of which are principally Papuan. In the shallow bifurcation of the tail it comes 

 nearest to I), balicassius. 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.).
