342 ZOOLOGICAL RESULTS 0¥ THE EUWEISTZOEI EXPEDITION. 



Dr. Sharpe has described an immature female (the type of L. castaneiceps) as having 

 the " median wing-coverts dusky, tipped vi'ith white, slightly tinged with yellow, and 

 forming a band " ; so probably the yellow tips to these feathers in the male in the 

 present collection indicate traces of immaturity. 



[A few examples of Liihder's Bush-Shrike were seen in the Mpanga Forest, east of 

 Euwenzori. — B. JB. W.]

[A few examples of this Bush-Shrike were seen at the north and south ends of 

 Ruwenzori among the acacia-trees. On the mountains it was seen in the Luimi and 

 Mubuku Valleys as high as 6500 ft., but it was always rather a rare bird. It has a 

 very curious note, quite unlike that of any other Shrike. — B. B. W.]

Iris dark brown ; bill black ; feet dull flesh-colour. 



The type of this species from Nandi is a somewhat immature bird, as may be seen by 

 the buff margins to some of the secondary-quills and the buff feathers among the 

 axillary plumes, as well as the pale horn-coloured tip and edges of the lower mandible. 



In the adult the inner margins of the quills and the axillary plumes are greyish- 

 white and the lower mandible is entirely black.
