Respecting the two preceding species, Nos. 224 and 225, 
Dr. Severtzoff gives a long note (p. 144), of which it may he 
advisable to give a detailed translation as follows;— 
“ In Turkestan there are three forms of 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. phmnicurus and L. isabellinus. 
“ L. isabellinus is larger than L. phmnicurus; the tail is 
rounded, the four central rectrices alone being of equal length, 
and the rest are graduated so that the outer ones are 4f n to 
5 W 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, 
or 4>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
