Mr. H. Durnford on North-Frisian Ornithology. 391 
Anas sparsa, Smith. 
Natal, May 15, 1873. 
Iris dark hazel. 
A common Duck, going about generally in pairs; they rise 
heavily, like a Pochard. I only saw them south of Pretoria. 
Sterna leucoptera. 
a, $. Transvaal, December 9th, 1873. 
Beak black; legs orange-yellow ; iris dark hazel. 
Seen in the Transvaal, on onr 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 99 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, which 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 ivory, 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
