The remarkable difference in size between examples of 

 the Corn- Buntings which I obtained in Gran Canaria led 

 me to suppose that there might be two distinct forms 

 inhabiting the island^ a resident E. c. thanneri and a 

 migratory race. I therefore collected a fair series from 

 difierent parts of the island, and my supposition was 

 strengthened by finding that all examples (with one excep- 

 tion) shot on the high ground had a wiiig-measurement of 

 93-102 mm., whereas those from the coast-line were con- 

 siderably smaller, with a wing-measurement of 85-90 mm. 

 The latter, without exception, all appeared to have much 

 lighter under parts than those from the hills. 



The Hon. Walter Rothschild and Dr. Ilartcrt very kindly 

 invited me to the Tring Museum, where the ample series 

 placed at my disposal soon convinced me that my Gran 

 Canaria birds all belonged to the same race. Dr. Hartert has 

 made a further examination of the series, and for this I am 

 deeply indebted to him. He is of opinion that the size 



t Di". Il.'irtert is of opiuion that the sex in specimeus h, k, I, and ii has 

 been wrongly determined. Certainly the measurementsof these examples 

 point to their being females, but as I did not dissect them myself I 

 cannot disprove this.
