THIS is the largest of its race, and measures three feet four inches 

 from the point of the bill to that of the tail ; expanse of the wing 

 nearly three feet ; the size, that of a small Turkey. The bill is in 

 some specimens a foot in length; and two inches and a half thick at 

 the base, the upper mandible red, inclining to yellow at the tip, the 

 lower pale yellow, except at the base, where it is black ; on the 

 top of the upper an appendage as large as the bill itself, turning 

 upwards, contrary to the true bill, which inclines downwards ; this 

 curved horn is eight inches in length, four in breadth, varied white 

 and black, marked longitudinally, with a black line on each side; 

 the edges of the mandibles jagged or dentated ; nostrils at the base 

 of the bill ; irides red ; eyelids furnished with dusky hairs ; plumage 

 of the head, neck, back, breast, and upper part of the belly black, 

 the lower and rump dirty white ; vent mixed black and white ; tail 

 twelve inches long, white, with a broad black bar in the middle ; 

 legs and claws dull grey brown. 



A specimen, in the collection of the late Sir A. Lever, was larger, 

 being four feet in length ; extent of wing much the same ; it varied 

 in wanting the black line on the bill. According to Mr. Marsden, 

 there is no appearance of a horn on the upper mandible of the young 

 bird, and at that period the irides are whitish.
