Sub-Order PHASIANL 

 Family TETEAONID^. 



The eggs of the Grouse are normally of a true oval form, but 

 occasionally they are elliptical or even pyriform. The shell is 

 smooth with a small amount of gloss, and is generally pitted with 

 very minute pores. 



Genus LAGOPUS, Briss. 



The eggs of the True Grouse are cream-coloured, stone-coloured, 

 reddish buif or pale olive, marked with specks, spots and blotches of 

 dark red-brown or chocolate-brown, frequentl}' so dark as to appear 

 black. Some are covered with spots and small blotches ; others with 

 well-defined blotches only ; and others again with huge confluent 

 patches which almost entirely conceal the ground-colour. An 

 occasional example may be met with which is unmarked and of 

 a whitish colour. 



The eggs of the different species of True Grouse cannot be 

 separated with any certainty either by size or colour.
