GENUS RHIPIDURA. 85 
three central pairs of tail-feathers uniform brown, next 
pair with paler tip, two outermost pairs dirty whitish, 
darker at the base of the inner web, chin, throat and a 
narrow line from the nostril above the eye white, chest 
and sides of body ashy brown, rest of lower surface in- 
cluding the under wing-coverts ashy fulvous. Bill narrower 
than in the allied species. 
48. Rhipidura sumbawensis, n. sp. 
Two specimens from Sumbawa, presented by Mr. van 
Lansberge, 1882. 
Closely allied to R. diluta, but with much broader bill, 
with the upper surface much paler brown, the quills edged 
with very clear rusty red, the three outermost pairs of 
tail-feathers more fulvous, less ashy than in RA. diluta, 
and the lower surface much more strongly tinged with 
fulvous. 
Forehead and lores blackisch, crown rufous brown, 
whole back and rump pale earthy brown with no grayish 
tinge at all, upper tail-coverts darker; upper wing-coverts 
like the back, median and greater as well as the primary 
coverts externally edged with rufous, quills brown, broadly 
margined with clear rusty red. Three innermost pairs of 
tail-feathers uniform sepia-brown, paler than in A. diluta, 
fourth pair broadly tipped with fulvous, fifth pair fulvous 
nearly up to the base, the outermost pair entirely fulvous 
with much paler outer web. Throat and a streak from 
the nostril above the eye white, duller in younger speci- 
mens, rest of under surface pale fulvous, somewhat tinged 
with ashy, under wing-coverts and thighs uniform clear 
fulvous, inner edge of quills vinous red. Bill broad, black, 
paler at base of lower mandible, feet flesh-color, iris black. 
Wing 8 cm., tail 8,7, outermost pair 7,3, bill 1,4, tar- 
sus 2. A probably younger specimen is smaller, the wing 
having 7,4, the tail 8 cm.
