118 ROUGH-BILLED PELICAN. 



and a Swan : length four feet six inches : beak thir- 

 teen inches, shaped as in other Pelicans, with the 

 addition of some singular protuberances on the top of 

 the upper mandible, from the base of which, for about 

 seven inches, the surface is plain ; at this part an 

 elevated ridge begins, about one inch and a half in 

 height, and one-third of an inch in thickness ; this 

 continues about an inch and a half on the beak, and 

 then other smaller ones take rise, of different sizes, 

 and continue decreasing in size in an abrupt manner 

 to the end of the beak : the colour of both reddish- 

 yellow, here and there inclining to red ; the under 

 mandible and pouch as in other species, but on each 

 side about the middle of the first, is a black spot, the 

 size of a silver penny ; and the bag is streaked with 

 fine lines of black, which are pretty numerous on the 

 fore part of it, most so next the end of the beak : the 

 plumage is wholly of a pure white, except the bastard ' 

 wings and quills, which are black : the shafts of the 

 larger ones white ; at the hind-head the feathers are 

 greatly elongated, forming a crest of four inches and 

 a half in length: the legs are black." Found in 

 America.
