to leave the Sumatran race un-named. A. s. vovdermaz is 
described by Buttikofer (Notes Leyden Museum, xv, p. 260 
(1893)), as having only the anterior half of the crown grey; 
this, however, is contradicted by Finsch, (of. cit. xxvi, p. 62), 
who regards all three forms as being absolutely identical. 
The species has not hitherto been recorded from Sumatra.

“Tris hazel or dark brown; bill black, feet black, often 
with a purplish tinge.” 
A forest bird, not found in secondary jungle or open 
country; exceedingly abundant in Korinchi up to about 7,000 
feet on the Peak, above which it was replaced by Niltava 
sumatrana. 
It was very tame and inquisitive in its habits and in the 
morning and evening two or three pairs were always to be 
found in our camp clearing at Sungei Kumbang, perching 
on projecting twigs and creeping about amongst the felled 
timber and tangled vegetation. The note was a low whistle 
or chirp. 
The species seems sufficiently distinct both from S. indigo 
of Java and S. cerviniventris of Kinabalu, North Borneo. 
Fully adult specimens always having the under tail-coverts 
deep rufous and the belly white without any tinge of fawn, 
though in younger specimens the under tail-coverts are paler, 
the belly often faintly tinged with bff, the blue of the upper 
surface duller, without the shining blue forehead and super- 
ciliaries and the feathers of the breast faintly tipped with buffy 
white. Salvadori (Joc. cit.) states that there is no appreciable 
difference between the sexes but in the series before us these 
can almost always be separated by the colour of the upper 
surface, which is a pure cobalt or indigo blue in the male, 
but everywhere less intense in the female.
