The chief differences between Lanius grimmi and L. elegans are as follows :- 



Lanius grimmi. 



Upper parts dull brownish French grey. Forehead, 

 lores, and an indistinct stripe over the eye dull 

 white. 



The broad patch behind the eye dull blackish. 



Larger wing-coverts dull black, broadly tipped with 

 dull white. 



Tail rather imperfect, the outer feather white, the 

 next blackish broadly tipped with white ; the four 

 central tail-feathers dull blackish, narrowly tipped 

 with dull white. 



Lanius elegans. 



Upper parts clear French grey. A narrow frontal line 

 and the lores black. 



The broad patch behind the eye clear black. 

 Larger wing-coverts entirely black. 



Outer tail-feather white, the next white with the 

 shaft black, and a small black patch on the inner 

 web, the next two black tipped with white ; the 

 four central tail-feathers black, with very slight 

 dull white tips. 



From which it will be seen that the chief characteristics of the present species are the white 

 forehead, lores, and stripe over the eye. 



The specimen figured and described is the type of the species, which was obtained by 

 Karelin in July 1836 on the Atrek, and for the loan of which I am indebted to the courtesy of 

 Mr. Pleske, Director of the Zoological Museum at St. Petersburg, this being the only specimen 

 I have had an opportunity of examining.
