PELECANIDiE. 



A young bird has the upper mandible dark brown, the 

 lower one pale brown ; irides brown during the first year, 

 then pale bluish-green, changing to emerald-green at the 

 end of the second year ; forehead, hind neck, back, wings, 

 and tail dark brown ; chin, throat, and neck in front dull 

 white, mixed with pale wood-brown ; lower part of neck in 

 front darker brown, mottled with white ; under surface of 

 body dull white, varied with a little brown ; sides and flanks 

 dark brown ; legs, toes, and membranes nearly black. 



A female with white on three of the tail-feathers is re- 

 corded by Mr. T. H. Nelson (Zool. 1880, p. 366) ; and 

 Saxby states that during the years 1869 and 1870 two pure 

 albinos, with light-coloured feet and bills, were observed 

 about the west coast of Unst.
