slightly over. It was met with in dark gullies hopping over 
boulders or logs, singly or in pairs, not taking to flight when 
alarmed but running with extreme agility. It was rather 
noisy and not particularly shy, the note consisting of a clear, 
melodious whistle. 
The adult female does not appear to have been described ; 
it resembles the male but has the general colour duller and 
less bluish black, the middle of the breast and abdomen 
greyish lavender, much more extensive than in the male, while 
. the silvery white superciliary stripe is quite lacking. 
Immature birds are sooty blackish brown, the feathers 
streaked and tipped with rusty brown. 
Fully adult males appear almost to lose the ashy grey 
tint on the middle of the abdomen and to become nearly 
uniform dark indigo blue beneath.

“Adult: Iris hazel, bill horn, pinkish at base, feet purplish

greenish, in other specimens dirty purplish mauve.” 
Abundant in the heavy forest near Sungei Kumbang, from 
about 4,000 feet, to aes over 5,000 feet but only within these 
limits. 
The sexes do not materially differ, but the colour of the 
male above is a rather more ruddy brewn than in he female 
Immature birds are streaked and spotted. 
There is little doubt that the large series recorded above 
should be referred to H. leucophrys, which has not hitherto 
been recorded from Sumatra, though it ranges east from the 
type locality Pangerango in Java, to the mountains of 
Sumbawa. 
From H. wrayi (Ogilvie Grant), from the mountains of 
the Malay Peninsula, it differs in having both sexes brown (in
