Expedition to the Eastern Canary Islands. 289 



January the 5th, 1914. I am much indebted to Mr. H. F. 

 Witherby for allowing me to publish these details. 



As already noted (Parti, p. 73), the dark-backed race, 

 Larus fuscus fuscus, is a very rare straggler to the Canary 

 Archipelago. 



Larus marinus. Greater Black-backed Gull. 



Larus ynarinus Linn. ; Bannerman, Part I. p. 85 ; Webb 

 & Berthelot, Ornithologie Canarieniie, 1841, p. 42 ; Bolle, 

 J. f. O. 1855, p. 177; 1857, p. 311. 



Messrs. Webb & Berthelot and Dr. BoUe in their works 

 cited above each mention Larus marinus as breeding on the 

 island of Allegranza, where the former assert that it was 

 ^"^assez commun." In those days this Gull was killed on 

 account of its down, which was sold in London as eider- 

 down ! Very probably this breeding station was soon 

 completely wiped out. We could not hear of any such 

 Gull being seen in the island or even in the neighbourhood 

 at the present day. 



Porzana porzana. Tlie Little Crake. 



Porzana porzana (Linn.) ; Bannerman, Part I. p. 63. 



Gallinula porzana Webb & Berthelot, Ornithologie Cana- 

 rienne, 1841, p. 40. 



An example of the Little Crake which had been shot 

 near Arrecife, was given to me in Lanzarote. Webb & 

 Berthelot record a specimen "of this very rare straggler'' 

 having been taken in the Canary Islands in March 1829. 

 Other observers have also mentioned the species as appearing 

 occasionally in the islands. 



One bird obtained from Lanzarote.

 Bustard.
