736 Air. D. A. Bannerman on the [Ibis, 



June I was surprised not to meet with the Sauderliug on 

 any of the islands which I visited : doubtless I was too late 

 in the year. I found a stuffed specimen in a collection in 

 Lanzarote (Ibis, 1914, p. 63). In Gran Canaria in February, 

 1912, Sanderlings were passing along the coast, and I 

 obtained specimens at Maspalomas on the 24th, 27th, and 

 29th of that month. The birds were in small flocks at the 

 mouth of the Charco (Ibis, 1912, p. 581). I have never 

 seen them in the north of this island. 



Range. The Sanderling breeds in Arctic America and on 

 the Siberian coast. It winters in Africa, south to the 

 Cape, and ranges throughout the greater part of the world, 

 visiting southern Asia, America, and Australia.

The Ruff is a Bird of Passage. 



It cannot be said to be numerous, in fact it is one of the 

 rarer Waders which I lieiieve to be a regular migrant 

 through the islands. 



The records are meagre in the extreme, and it would 

 perhaps have been wiser to include the Ruff" in the 

 list of Occasional Visitors. Competent observers are rare 

 in the Canary Islands, and as Meade-Waldo and Polatzek 

 both considered the Ruff to be a regular visitor, and as the 

 observations of these ornithologists jointly cover a number 

 of years, with a considerable period between them, I feel 

 justified in placing the Ruff under this heading. 



Meade-Waldo found it " not numerous, but pretty 

 regular," especially on the Laguna plains after a heavy fall 

 of rain (Ibis, 1893, p. 205), and shot a specimen on the 

 21st of February (MS. diaries). 



Cabrera ol)tained specimens near Laguna (Catalogo, p. 59). 



Polatzek remarks (Orn. Jahrb. 1909, p. 131) that 

 it " appears often on its passage through, including the 

 eastern islands." 



Von Thanner shot a male in Fuerteventura on the
