There are only lour birds in the British Museum from 

 the west coast of Africa, all of which I believe to belong 

 to this large race of Wheatear, (Enanthe oenanthe leucor- 

 rhoa : —

 e. Bo, Sierra Ijeone.

There are as well two specimens from the Azores also 

 referable to the Greenland Wheatear : —

 Nov. 1907. 



The following records relating to this species in north-west 

 Africa are also worthy of notice here : — 



Dr. Hartert (Nov. Zool. x. 1903, p. 295) records three 

 adult birds from tlie Rio de Oro obtained in July 1902, and 

 four juvenile specimens shot in the same month, Mhich had 

 doubtless been bred there FRiggenbach Coll.] . 



In a later Expedition Hartert found it in the western 

 Sahara [near Oued Mya] on the 10th of April, 1912 (Nov. 

 Zool. XX. 1913, p. 54). 



Range. The Greenland Wheatear breeds in Greenland' 

 and north-east America. It migrates through western 

 Europe to the Azores and through north-west Africa to 

 Senegambia and Sierra Leone. It is almost certain to be 

 this form which visits the Canaries on mijiiation in s[)i'ing 

 and autumn.
