THE BLACK-BACKED KALIJ. 195 



Females. — Length, 18*0 to 21*0; expanse, 25*0 to 27*0 ; wing, 

 8*1 to 8*8 ; tail from vent, 7*5 to 8*6; tarsus, 27 to 2'9 ; bill 

 from gape, 1*15 to 1*25. Weight, 1 lb. 14 ozs. to 2 lbs. 4 ozs. 



The bill is yellowish or greenish horny, pale yellowish at tip, 

 dark at base ; legs and feet pale horny brown ; claws and spurs 

 often with a more fleshy tinge ; irides bright orange brown 

 to dark brown ; orbital skin bright red. 



The Plate. — As usual the colours of the bill, legs, and feet are 

 not quite correct ; and the plate fails to convey an adequate 

 idea of the lustrous blue black of the male's upper plumage.
