2. Colyinbns capcnsis [Lcht.] Salvad.\ Xjiri. II.. VI.; Lake 

 Xakuro, I. With young ones about two days old on Feb. 1 5th

 Kilimanjaro. Frequently on the Xjiri Lakes and Merker Lakes.

 Island in Pangani in August.

Phalacrocoracidse 



5. Phalacrocorax liicidiis lugubris Riipp. Merker Lakes, XI. 

 This great cormorant was observed by me only on the Merker 

 Lakes, Lake Natron, and the Xjiri Lakes. While on the wing 

 it gave out a curious whistling kind of cry. 



6. Phalacrocorax africanus (Gm.). Bagamoyo, VII. Seen 

 everywhere frequently, in the coast region between Dar-es-Salaam 

 and Tanga, as well as on rivers and lakes. 



7. Anhinga rnfa (Lacep. Daud.). Central Pangani, III. 

 Brooding. This strange-looking bird with a snake-like neck I 

 found nesting halfway up the Pangani River. Its nests were 

 in the branches of acacia-trees stretching over the river, about 

 14 or 15 feet above the water. I found them only on small 

 islands in the middle of the stream. The eggs are of a bluish 

 colour and covered with a strong coating of chalk. 



Pelecanidae 



8. Pelecanus roseus Gm. On the Victoria Nyanza, the 

 Merker Lakes, XL; Lake Xayasha, I., frequently. On the
