Description. Of the same general appearance as L. aucheri, but the 
under parts white tinged more or less noticably with rosy, never any grey ; 
white on the wings much as in LZ. aucheri ; tail with the outer (sixth pair) of 
rectrices white, except for a partially black shaft, fifth pair white except for 
the shaft and a narrow band along the inner web next the shaft, third and 
fourth tipped with white, first and second with only a very narrow white tip ; 
under wing-coyerts usually pure white but sometimes a trace of the grey patch 
on the primary under-coverts; bill horny and pale (occasionally black). 
Length 8:75 inches, culmen 0°65, wing 4°25, tail 4:0, tarsus 0:9. Khar- 
tum, ¢,11.1.04. (Zaphiro.) 
A young bird has the back an earthy-grey ; the black face-band hardly
