Respecting the two preceding species, Nos. 224 and 225, 

 Dr. Severtzoflf gives a long note (p. 144), of which it may be 

 advisable to give a detailed translation as follows : — 



"In Turkestan there are three forms oi Lanius phmnicurus, 

 the first of which inhabits the mountains (var. montana*) , the 

 second the lowlands (var. caniceps) ; and the third, the steppe- 

 form, which differs constantly, though slightly, and may be 

 considered a distinct species, is L. isabellinus. On examining 

 a considerable series, I did not find any specimens inter- 

 mediate between L. phcenicurus and L. isabellinus. 



" L. isabellinus is larger than L. phcenicurus ; the tail is 

 rounded, the four central rectrices alone being of equal length, 

 and the rest are graduated so that the outer ones are -i'" to 

 5'" shorter than the central ones ; the 1st quill is short, being 

 once and a half as long as the coverts, 4 = 3>5>2>6, 

 or4>3>5>6>2. 



"Adult male in spring. Crown, nape, and two thirds of the 

 back and shoulders same colour ; lores, lower part of the 

 cheeks, and a line above the eye brownish white, and on the 

 upper part of the cheek there is a black line ; rump and tail 

 light brown ; underparts light brownish, with a yellowish 

 tinge, in old birds with a rose tinge, which is most apparent 

 on the sides ; throat and breast sometimes pure white ; quills 

 dark greyish brown, with pale yellowish grey margins, the
