72 Mf. D. Ad Banuernian on an Ornithological 



20. Toianus nebularius. — Only one Greenshank was seen. 



21. Numenius a. arquatus. — Four Curlews were flushed 

 on the hummocky plain at the foot of the Montana de las 

 Agujas, It would not have been surprising had we dis- 

 covered tliem breeding here, as Herr von Thanner recorded 

 the nesting of this species in the south of Fueiteventura 

 (Orn. Jahib. 1908, p. 313). 



22. Numenius J-). ph(Bopus. — The Whimbrel was met witb 

 On all parts of the coast, the rocky pools and exposed reefs 

 being exactly suited to their habits. 



23. Sterna s. sandvicensis. — According to the fishermen^ 

 I'erns, or " Garajaos " as tlie islanders call them^ visit 

 Graciosa whenever " Sardinas ^' are particularly numerous. 

 1 did not meet with either the Common or Sandwich Tern 

 anywhere in the islands. 



24<. Larus cachinnans. — The Yellow - legged Herring 

 Gulls are very plentiful in Graciosa, although they do 

 not actually breed there. They were very tame indeed, 

 and frequented the small fishing village in numbers. The 

 chief breeding-station of this species in the eastern islands 

 is the Roque del Este, while others probably nest on the 

 high cliffs iu Lanzarote, known as El Risco. 



KoTE. — It is worthy of special notice that no Lesser 

 Black-ba(;ked Gulls {Larus fuscus affinis) were seen at all 

 during the expedition. This proves more or less conclu- 

 sively that the species does not breed in the eastern Canary 

 Islands, as I had half expected to find. If any of these 

 Gulls had been breeding on the outer islets the fact could 

 hardly have escaped our notice, as they would undoubtedly 

 have visited the Graciosa fish-curing depot, where we were 

 constantly on the look-out for them. All the smaller islands 

 and rocksj with the single exception of the Roque del Este^ 

 were visited by the expedition. 



It can therefore be inferred that the Avestern light-haclied 

 race [Larus fuscus nffinis Reinhardt) is a regular winter
