From these measurements it will be seen that whereas the two 

 species of eggs overlap in length, they do not do so in breadth, 

 the eggs of Carduelis c. niedecki being considerably smaller. Never- 

 theless, when these sets are laid out together I And them so similar 

 that it is almost impossible to distinguish their species without 

 looking at the distinctive marks. In comparison with these 

 small eggs, the measurements of the largest sets should prove 

 interesting : —

 Of 18 eggs taken by me in 1920, the Rev. F. C. R. Jourdain, 

 M.B.O.U., sends me the following measurements (in milhmetres), 

 av. = 19-1 X 13*97 :—

N.B. — In this latter series the longest egg is also the narrowest. 



There is little to be said about the colouring and marking of 

 the eggs, as they approximate to British specimens ; and markings 

 are principally at the larger end, and though rarely in the form 

 of a ring are sometimes confined to a cap. There is also a some- 

 what erythristic type of eg^ of which I have taken a few sets, and 

 they are invariably large and curiously shaped eggs, which I describe 

 as oblate ovals. Their ground colour i^ a pale pinkish-brown with
