It will be seen that there is some slight overlapping 

 in measurements, but I find that this does not amount 

 to more than 2 per cent, of individuals — which agrees 

 exactly with Herr Stejneger's results. Herr Winge states 

 that no Wheatears from Greenland which he has examined 

 measure less than 100 mm. in the wing, with which state- 

 ment I can quite agree (the two or three females of 99 

 mm. which I measured probably being rather worn 

 specimens) ; moreover, I have not been able to find any 

 Wheatears shot outside the range of the Greenland 

 Wheatear which do not conform in wing measurement 

 to the small race. 



All these birds were measured by myself, and only those 

 with which full data were recorded have been utilised.
