116 Mr. D. A. Bannennaii on the [Ibis, 



Islands, while from the Fiji group a distinct species of 

 Bulweria occurs, a very curious fact already pointed out 

 by Messrs. Iredale and Mathews (Ibis, 1915, pp. 607-608). 

 I have dealt with the various breeding-places of this Petrel in 

 the north Atlantic islands in ' The Ibis/ 1914, pp. 488-494. 



Family Podicipid.e. 



Podiceps nigricoUis nigricollis. Black-necked Grebe. 



Podiceps nigricoUis G. L. Brehm, Vog. Deutschl. 1831, 

 p. 963 — Type locality : E. Germany. 



The Black-necked Grebe is a Rare Visitor. 



It has been met with on one occasion only. During 

 my expedition to the Eastern Canaries, my taxidermist, 

 Mr. A. II. Bishop, identified a small flock of these Grebes 

 which had flown onto the salt lake known as the Lago 

 Januvio in Lanzarote (Ibis, 1914, pp. 57, 270). The birds 

 arrived on the 21st of May, 1913, but only remained a short 

 time before flying over the dividing spit of land out to sea. 

 The weather was boisterous and the Grebes had evidently 

 come in to shelter from the stormy seas on the calm water 

 of the " Lago.^' We watched them through powerful glasses 

 for some time. 



Range. The Black-necked Grebe breeds in central and 

 southern Europe and ranges east through central Asia to 

 Japan. It has been recorded from the Azores, and is found 

 throughout the greater part of Africa. 



Podiceps fluviatilis. Little Grebe.

A Rare Visitor. 



A Little Grebe has been recorded on one occasion only 

 from the Archipelago.
