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, 
A. capitalis and H. intermedius, and Dr. Sharpe (Ibis 1889, 
p-. 190) believes that H. picatus and H. capttalis 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 HZ. 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 1898, 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 HA. picatus. It is, on the 
contrary, very probable that H. capitalis does not exist in 
Borneo at all and 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 H. intermedius Salvad. might be identical with 
H. picatus. Count Salvadori (Uccelli di Sumatra, p. 209) 
says that H. intermedius agrees with 4. 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
