Mr. Percy F. Bunyard exhibited the following eggs 

 from his collection : — 



Razorbill (Alca tordd). A series of 214 British eggs, 

 showing remarkable variation, the extreme forms being 

 represented by heavily pigmented eggs, in some cases almost 

 entirely concealing the ground-colour. In others the whole 

 of the large ends were completely covered. The modified 

 forms were represented by eggs almost entirely without 

 markings, varying in ground-colour from bluish-white to 

 reddish-brown — the type-eggs with white ground showing 

 considerable variation in the arrangement of the markings, 

 heavily and slightly blotched and veined eggs predominating. 



A rare variety with purplish-red ground-colour was also 

 shown. 



Great Auk [Alca impennis). An enlarged photograph 

 of nine eggs representing the Ohampley series before being 

 dispersed, unfortunately only three of which now remain 

 in this country. This photograph is unique, as it is unlikely 

 that nine eggs will ever again be brought together. 



( COMMON Guillemot (JJria troille), A series of 420 eggs, 

 mostly from Yorkshire, arranged in twelve drawers in their 

 various forms. These were represented by veined and 

 spotted eggs, as were also the greenish-blue ground-type 

 eggs. Extreme forms in which the vein-markings are 

 evenly distributed over the whole surface, and those with 

 the surface almost wholly concealed by heavily pigmented 

 blotches or suffused markings were well represented ; also 

 self-coloured eggs of blue, bluish-green, and pure white. 



Brunnich's Guillemot (Uria lomvia). A series of eight 

 eggs from Spitsbergen. These do not differ from those of 

 U. troille ; they do not, however (judging from the material 

 available for comparison), appear to show so much variation, 

 or run into such extreme forms. 



Black Guillemot ( Uria grylle). A series of 30 clutches 

 from Orkney, etc., showing three distinct ground-colours, 

 i. e., buff, greenish, and white. Eggs showing exceptionally 

 large blotches and underlying markings were well repre- 

 sented.
