Adult. Birds from the island of Socotra are intermediate between 

 L. algeriensis and L.fallax. The general colour above is a little darker 

 than ill L. falJax, and paler than in L. ah/eriensis ; underparts just 

 as grej' as in L. ahjerlcnsis ; but the Socotra specimens more resemble 

 L. faUax in having a faint indication of the white superciliary stripe, 

 and in having the narrow black frontal band still more developed. 

 The most remarkable point in which these birds differ from their 

 allies is the great development of the bill, which is both longer and 

 stouter, and unusually hooked. Bill and feet black. 



Total length about 9 inches.
