471. Lanius fallax.
Finsch's Grey Shrike.
Lanius fallax, Finsch, Trans. Z. Soc. vii, p. 249, pl. xxv (1870); Gadow, Cat. B. M. viii, p. 247, pl. viii.
Coloration. Resembles L. lahtora in general appearance. Differs in having the black on the frontal part of the head confined to the bristles over the nostrils and to a very narrow band at the base of the upper mandible ; in having the inner webs of the secondaries blackish brown margined with white and the lower plumage tinged with ashy ; in having the upper plumage paler grey; and in having the lesser wing-coverts entirely grey. Of the same size as L. lahtora.
From L. assimilis this species differs in having the inner webs of the secondaries almost entirely brown and in having the upper plumage darker.
L. assimilis and L. fallax are very closely allied, but there is no difficulty in separating the two, if the inner webs of the secondaries be examined. . Neither of them can possibly be confounded with L. lahtora, the colour of the lesser wing-coverts being sufficient at all ages to distinguish the latter from the other two.
Distribution. I have examined the four birds procured in Abyssinia by Jesse and named L. fallax by Finsch. To the same species must be referred a Shrike procured by Blanford at Gwadar in Baluchistan in December, and another procured by Lieut. Burgess, probably in the Deccan. I have not been able to examine any other specimens collected within our limits.
L. fallax occurs in Abyssinia and Nubia, Palestine, Mesopotamia, Muscat, and Afghanistan.
