30 TETKAONID^. 



The eggs of the different races of the Euffed Grouse are ex- 

 tremely variable in colour. The majority are of various shades 

 of cream- colour : some are perfectly unmarked ; others show 

 a few small spots of pale rufous; a few are rather profusely 

 spotted with pale reddish brown, and some are marked with a few 

 pale washed-out purple blotches. Three specimens in the Collec- 

 tion are of a buff-colour, minutely but thickly speckled with dark 

 rufous. 



One specimen is unusually large and measures 1'8 by 1-35. Others 

 of normal size measure from 1-45 to 1-7 in length, and from 1-1 to 

 1-3 in breadth.
