taken by that gentleman in Mesopotamia during the recent 

 campaign in that country. 



Mr. Percy F. Bunyard exhibited the eggs of thirty species 

 of British Warblers from his collection : — 



Whitethroat {Sylvia communis). A series embracing 

 practically every known form and many remarkable 

 varieties ; amongst the latter erythrism was represented 

 by four clutches, British and Continental. Also a clutch 

 of five from Surrey almost pure white with suffused grey 

 underlying markings. 



Lesser Whitethroat {Sylvia curruca) . A representative 

 series in which the rare cyanic form was conspicuous j the 

 characteristic large suffused brown markings were par- 

 ticularly noticeable in the type eggs. 



Garden-Warbler (Sylvia sim])lex). A very beautiful series 

 showing extreme and modified forms, and varieties with pure 

 white and greenish ground. 



Blackcap (^Sylvia atricapilla) . In this series varieties 

 were well represented ; conspicuous among them are two 

 clutches of five almost pure white eggs from Suffolk. 

 Compared with " simplex " eggs they were smaller on the 

 average. The type eggs of ^''atricapilla'^ and "simplex" 

 could not easily be confused ; varieties, however, require 

 careful identification. A unique series of twenty-five clutches 

 of the erythristic form were also exhibited, British and 

 Continental, and which had taken thirty years to obtain. 



Sardinian Warbler (Sylvia melanocephala) . A series from 

 Spain, in which the erythristic form was well represented. 

 These eggs apparently go through a greater variation than 

 " unclatus " eggs, which they somewhat resemble. 



Orphean Warbler {Sylvia orphea). Four clutches of 

 typical eggs from Spain. 



Subalpine Warbler {Sylvia subalpina). Three clutches 

 from Greece and Austria, showing great variation. 



Dartford Warbler (Melizophilus undatus). A series 

 showing great variation, British and Continental ; among 

 the former, clutches with white ground were conspicuous, 

 the greenish form predominating ; among the latter were
