pure white with a few black cross-bars on the anterior 

 part; the shorter upper tail-coverts are also white, while 

 the longer are black like the three innermost pairs of tail- 

 feathers. The three outer pairs of tail-feathers are black 

 with white tip, which latter is largest on the outermost 

 pair, where it has an extent of 3 cm, on the outer, and 

 of about 2 cm. on the inner web. The basal third of the 

 outer web is black. In one of the two females even the 

 fourth pair are, though narrowly, tipped with white. 



In a treatise on Sumatran birds (N. L. M. 1887, p. 52) 

 I uttered some doubts as to the distinctness of H. picatus, 

 H. capitalis aud H. iyitermedius, and Dr. Sharpe (Ibis 1889, 

 p. 190) believes that H, picatus and H. capitalis are iden- 

 tical. But in the same year, Mr. Oates (Faun. Brit. India 

 Birds, I, p. 471) points out a constant distinguishing cha- 

 racter, saying that the adult male of H. picatus has head 

 and back glossy black, while in H. capitalis only the head 

 and hind neck are black, strongly contrasting with the 

 back, which is brown. As females and young birds of both 

 species are alike, the difference is entirely based upon the 

 color of the back in adult males. Hemipus capitalis is 

 enumerated by Mr. Ch. Hose (Ibis 1893, p. 395) in his 

 paper on the birds of Mount Dulit. But this is very pro- 

 bably a mistake, as the same bird is mentioned in a pre- 

 vious list (Ibis 1892, p. 434) as H. picatus. It is, on the 

 contrary, very probable that H. capitalis does not exist in 

 Borneo at all aud that the only highland-form occurring 

 on that island as well as in Sumatra belongs to H. picatus. 



In my above mentioned paper on Sumatran birds I sug- 

 gested that B. intermeclius Salvad. might be identical with 

 H. picatus. Count Salvadori (Uccelli di Sumatra, p. 209) 

 says that H. intermedins agrees with //. picatus in the 

 shining black color of the upper parts, while in the extent 

 of the white tips to the tail-feathers it resembles H. capi- 

 talis from Nepal. But since there is, in fact, no difference 

 in the extent of the white color on the tail between the 

 mentioned species, this cannot be used as a distinguishing
