described as a faintly greenish-grey. As a rale the paler the ground, 

 the paler the markings, and vice versa. Exceptionally beautiful 

 marbled eggs are met with, as also unmottled pale creamy varieties. 



I have never, however, seen one that could be taken for an egg 

 oi fasciatus.^^ 



" The eggs vary in length from 1-32" to 1'6" and in breadth from 

 0-93" to 1-11"; but the average of 70 eggs is 1-45" by 1-03"." 



Reducing Hume's figures to millimetres we get respectively 33*6 

 to 40-5, 23-2 to 28-2 and 36-8 x 26-2 mm. 



Gates gave the measurements of the eggs in the British Museum 

 as running u.p to 1-15" (29*2 mm) in breadth and the average of 129 

 eggs in that Museum added to 102 other eggs of which I have 

 obtained the measurements, is exactly the same as that given by 

 Hume. 



It is not possible ever to confound these eggs with those of the 

 Painted Sand-Grouse ( Pterocles fasciakis ) for these latter are always 

 salmon, bright buff or pink in general tone, whereas those of the 

 Common Pintail Sand-Grouse ( Fterodurus exustus ) are always 

 greyish, or olive grey in tint when looked at as a whole.
