Bertrand's Masked-Weaver inhabits East Africa between 

 the Zambesi aiid Zanzibar. 



The species was discovered by Mi'. Alexander Whyte at 

 Zoraba and ou the Milanji plains, and named after Dr. P. L. 

 Sclater's son, Bertrand Lutley Sclater, then Commander of tbe 

 Police Force of British Central Africa, and who died a few 

 years later in Ugando, much regretted by all who knew him. 



This fine, well-marked Weaver has also been procured in 

 the highlands, at the northern extremity of Lake Nyasa, and 

 at Songea, by Dr. Fiilleborn, and in the Ulugura country on 

 the Upper Kingani River by Dr. Stulhmann.
