in L. (ih/erieiisis beiug confined to tbo upper breast and the flanks 

 in some examples (as e. y. in Jesse's specimen), whilst in others the 

 underparts are almost white. 4th. There is a superciliary stripe, 

 ■which, although narrow, is never wanting. Bill and feet horny 

 colour. 



The ifounr/ birds are much paler than the adult, and tinged above 

 with pale tawny colour ; underparts dull white ; loral and frontal 

 region dull white instead of blackish ; ear-coverts, quills, and tail- 

 feathers brown instead of black ; all the wing-coverts are brown 

 and broadly edged with dull white : bill and feet pale horny yellow. 

 These are the bii'ds which have been called L. jjallidirostris by some 

 authors.

Obs. In the British-Museum collection are two specimens from 

 Palestine, one from Mesopotamia, and a fourth from Abyssinia which 

 have a well developed black frontal band ; and the three males show a 

 rather conspicuous grey tinge on the upper breast and on the flanks. 

 The bills and feet are black ; and the general colour above is a shade 

 darker than in the other specimens of X. fullax. Consequently these 

 four specimens are intermediate between L. fallax and L. uucinatus 

 from Socotra, from which, however, they further differ by their more 

 slender bill (except the male specimen from Gennesareth, which has 

 a bill just as much developed as in most of the Socotra birds), and 

 much more white on the inner web of the secondaries.
