250 DR. 0. FINSCH ON BIRDS FROM NORTH-EASTERN 
cinerascente lavatis; remigibus nigricanti-fuscis, a basi ad medium fere pure albis, mi- 
noribus limbo apicali albo; scapularibus fuscis apicibus albo marginatis, pogonio interno 
versus basin sensim albiore; subalaribus albis; rectricibus mediis fusco-nigris, limbo 
apicali tenui albo, extima fere tota alba, scapo latius fusco; secunda fusca, macula 
terminali majore alba; rostro nigricante, mandibule dimidio basali albo; pedibus 
plumbeis. 
Male. All the upper parts, including the rump and upper tail-coverts, delicate ashy 
grey; a very narrow frontal margin and a broad stripe, which covers the lorum, eye, 
and region of the ear black, margined above by an indistinct narrow whitish line; 
cheeks, chin, and throat white, all the remaining underparts of a light ashy grey, 
much lighter than the back; vent and under tail-coverts white, the same as the under 
quill-coverts, which are washed faintly with grey; primaries brownish black, on the 
basal half of both webs nearly white, forming a conspicuous white speculum; secon- 
daries brownish black, on the basal half of the inner web whitish, and tipped broadly 
with white; quill-coverts brownish black, some newly developed secondaries have the 
basal half white, the same as the primaries; the longest of the shoulder-coverts whitish, 
but almost covered by the lesser shoulder-coverts; the tail-feathers black, tipped with 
white, narrowest on the two middle ones, increasing in breadth externally; the outmost 
tail-feather white, with the shaft blackish; the second feather margined with white on 
the outer web. Jill blackish horn-brown; the basal half of the mandible pale horn- 
colour; legs dark horn-brown. 
The three females are similar, but want the narrow black frontal margin; the bill 
is paler; two specimens show the middle of the breast tinged faintly with isabelline 
colour. 
All the specimens are in change of plumage. In moulting the female shows the back 
washed faintly with pale brown, indistinctly barred with darker lines.

Being unable to refer this Shrike with certainty to any of the allied species, I must 
consider it to be new. It comes nearest to LZ. lahtora, Sykes, which occurs also on the 
shores of the Red Sea, but differs in the pale greyish tint of the under parts, which are 
decidedly white in L. Jahtora. Otherwise there is scarcely any difference. The greyish 
tint of the belly, which all the specimens in Mr. Jesse’s collection exhibit, shows its 
relation to L. algeriensis, Less.; but in this species the grey tone is much darker, the 
upper parts are dark ashy grey, and the outermost tail-feather is black with a broad 
white apical spot. L. pallidirostris, Cass., also an allied species, has the bill pale horn- 
colour, the under parts white. J. pailens is distinguished at once by the white rump.
