The Grey-crested Helmet-Shrike ranges from the Unyam- 
wesi country of German Kast Africa into Kikuyu in British 
East Africa. 
The species has, in its most southern known range, been 
recorded from Ugalla (Trotha) to the east of Lake Tanganyika 
in about 6° §S. lat. 
Towards the south and east of the Victoria Nyanza 
Mr. Oscar Neumann has procured specimens at Muansa, 
Negara, Mousse, and Ssero. The type was discovered at 
Lake Naiwasha by Fischer, where he killed the female off 
the nest on May 11. This was placed in the fork of a tree 
about ten feet from the ground. It was shallow and cup- 
shaped, 3°2 inches wide inside, and was composed of grass- 
stalks and spiders’ web. It contained one egg, which was 
ereenish-blue with a zone of many dull greyish-brown and 
red-brown spots, and measured 0°84 x 0°68. In Kikuyu it 
has been obtained by Lord Delamere in the Kedong valley, 
in which locality Mr. Jackson shot an adult female and a 
full-erown young bird out of a small flock. Doherty also 
obtained a fine series for the Tring Museum near Escarpment 
Station in British Hast Africa. No doubt all the members
