108 Mr. D. A. Bannerman on the [Ibis, 



This species is named binominally as I am not yet quite 

 sure to wliicli form it should be assigned. As Tsohusi has 

 actually named the Canarian Corn-Bunting E. c. thunneri, 

 it may simplify matters to accept this name for what is 

 undoubtedly a resident breeding-bird in all the western 

 islands of the Arcdiipelago. Whether the Corn-Buntings 

 iu the eastern islands are best considered Partial Residents 

 or Summer Visitors it is most difficult to say. 



The small, light-breasted birds which I collected on the 

 coasts of Gran Canariaadd to the difficulties. I belieye it to 

 have been a migrant, and if that was so, and these visitors 

 breed with the island form, it may account for the varia- 

 bility of the Canarian Corn-Buntings and my difficulty in 

 separating them from typical examples. Certainly the 

 evidence at presen,t available points to the Corn-Bunting 

 being resident in the western islands, many visiting the 

 eastern islands in summer. 



I gave the matter a great deal of attention in 1913-14, 

 and my lemaiks will be found in 'The Ibis,' 1914, 

 pp. 240-243, which had better also be consulted. 



I quite realize that the question was left in an unsettled 

 state, and that it is not even now cleared up satisfactorily. 



Briefly my conclusions were as follows, except that I now 

 believe it will simplify matters to accept E, c. thanneri as 

 valid : — 



1. That there is a resident race of Corn-Bunting confined 



to the high ground in the western islands of the 

 gioup, named by Tschusi E. c. thanneri {cf. Orn. 

 Jahrb. 1903, p. 162— Type locality : Tenerife), dark- 

 breasted and large in size (wings 92-102 mm.), which 

 it is difficult to distinguish from typical E. c. calandra, 

 and which when I wrote on this bird in 1914 I did 

 not separate. 



2. That there is a Corn-Bunting to be found in the island 



of Gran Canaria, confined to the coastal region, light- 

 breasted and small in size (wings 85-90 mm.), which 

 appears to arrive in the island in February. This 

 bird does not agree with E. c. thanneri.
