might easily escape notice altogether.

The single specimen of this Shrike was obtained in the 
desert on March 15 th ; it agrees in every detail with the 
type of L. asshnilis in the Tring Museum.

L. leuconotus is probably the same as L. dealbatus (de 
Filippi). Our two specimens agree in every way with the 
type of L. leuconotus of Brehm. 
This Shrike is not common, but it is one of the most 
conspicuous birds of the desert. It was usually seen singly, 
and shewed no signs of breeding.

The females are considerably smaller than the males, the

This species haunts the very densest scrub and is one of

Like so many of the species of this region, it is more often 
seen during the last hour of daylight than at any other time, 
and its loud piping whistle may sometimes be heard a long 
time after sunset.

In the females the wing is distinctly shorter than in the 
males. 
The native name of this species, which means " Seven 
Sisters,^^ is very appropriate, inasmuch as it is nearly 
always seen in family-parties of six or seven. As a means 
of escape, it quite as often trusts to its feet as to its wings, 
hopping along the ground in great bounds of two or three 
yards at a time, with tail uplifted, and chattering angrily the
