Adidl male. — Differs from all the preceding species in the much darker grey 

 colour of the upper parts, and in having the breast, sides, and flanks strongly 

 washed with grey, contrasting in typical examples with the white chin and throat. 

 The ])riniaries have the basal lialf white, and e.^tending for about an inch bevond 

 the black greater coverts ; the secondary (piills have the tips white, the outer web 

 black to the base, the inner web mostly black, shading into white towards the 

 margin and base ; the tail is coloured much as in L. major, the outer pair of 

 feathers being white, with the shaft and basal half of the inner web black ; the 

 fifth jiair black, with the terminal third of the inner web and the margin of the 

 outer web white ; on the fourth and inner jiairs the amount of white gradually 

 decreases till the middle pair are entirely black, with the t^xceplimi of a tiny white 

 sjiot at the extremity.

Adult female. — IJcsenibles the adult mnle. 



An immature bird (with the wings and tail two-thirds grown) lias tlie upper 

 parts strongly washed with brown, the breast and under parts strongly sulfnsed 

 with the same colour and indistinctly barred witli dusky ; the wing-coverts widely 

 edged with brownish buff, the edges to the greater secondary coverts forming a 

 well-defined baud across the wing (Tristram coll. ex Mus. Liverpool). In a 

 somewhat older example the bars on the breast-feathers are almost impercej)tible. 



Examples of this sjiecies I'rom the Canary Islands {Laiiiui^ al<jerien.si.H k(rni(ji 

 Hart.) are on the whoh^ lighter than North African birds, but with the large series 

 from both localities now before us it is — in my opinion — impossible to separate them. 

 Many light birds ipiite as light as those found in the ( 'auary Islands occur among 

 the North African series, while not a few darker forms, a])]iroaching tyjiical 

 L. alyerieitsis, may be seen among a Canary Island series. We are indebted to 

 Dr. H. 0. Forbes for the loan of a fine series of Shrikes from the Canary Islands, 

 mostly collected by Canon Tristram. 



• There can be hardly au.v doubt that tlie bird described by llainl is a typical example of L. alycrij:mi»; 

 some miotalie has evidently been made iiboul the label, which states lliat tlie bird was cullected in 

 California by Dr. (iamble. Mr. Kidgway agrees with this identification ; cf. Auk. xiv. p. 323.
