Mr. II. Durnford on North-Frisian Ornithology. 391 



Anas sparsa, Smith. 

 Natal, May 15, 1873. 

 Iris dark hazel. 



A common Duck, going about generally in pairs ; tliey rise 

 hea^aly, like a Pochard. I only saw them south of Pretoria. 



Sterna leucoptera. 

 a, ^ . Transvaal, December 9tb, 1873. 

 Beak black; legs orange-yellow ; iris dark hazel. 

 Seen in the Transvaal, on our way down, in flocks frequent- 

 ing the marshes and lagoons. 



Plotus levaillanti ? 



I obtained one specimen which I can only refer to this 

 species, and observed several more ; they frequented the 

 " sluits " and pools of water of the Transvaal. 



Pelecanus . 



I once or twice saw Pelecans soaring high in the air in 

 circles. At Bamangwato I saw a skin of one, wliich I unfor- 

 tunately neglected to obtain ; I was told it came from the 

 lake (Lake N'gami) where it breeds, and was only found 

 there. 



StRUTHIO AUSTRALIS. 



Still common, but very much hunted for the feathers, 

 which, with ivorj-, are the two principal articles of trade with 

 the Kaffirs. Ostriches seem to lay from August to October, 

 as the natives bring in their eggs during all that time. The 

 stride of an Ostrich is enormous, being equal to about three 

 steps of a man. They are generally seen in pairs. 



XXXIX. — Ornithological Notes on the North-Frisian Islands 



and adjacent Coast. By Henry Durnford. 

 Being desirous last spring of making an egg- collecting expe- 

 dition, my brother and I pitched upon the North-Frisian 

 Islands, lying off the coast of Schleswig, as the scene of our 

 operations. Several English ornithologists have before visited 

 them ; but, as far as I am aware, no account of them has
