and retiring bird, and but for its rufous-coloured tail it 

 might easily escape notice altogether.

The single specimen of this Shrike was obtained in the 

 desert on March 15th ; it agrees in every detail with the 

 type of L. assimilis in the Tring Museum. 



31. Lanius leuconotus C. L. Brehm.

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 

 wing being from 4 to 6 mm. shorter. 



This species haunts the very densest scrub and is one of 

 the most shy and retiring birds that we met with at Sliendi. 



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 

 yai'ds at a time, with tail ui)liftcd, and chattering angrily the
