4 RHINOCEROS HORNBILL. 



except the lower part of the abdomen and tip of 

 the tail, which are white: the bill, which is enor- 

 mous in proportion to the bird, measures about 

 ten inches in length, and is of a slightly curved 

 shape, sharp-pointed, serrated in a somewhat irre- 

 gular manner on the edges, and furnished at the 

 base of the upper mandible with an extremely 

 large process, continued for a considerable space 

 in a parallel direction with the bill, and then turned

 portions by a longitudinal black line, the part above 

 the line being of a bright red, the part below yellow, 

 and the back part or rising base, next the head,

 process, being black at the base, the remainder

 the legs are short, strong, and of a pale yellow 

 colour. In the specimen described by Monsr. 

 Levaillant the abdomen was entirely black; the 

 tail, as in the above described specimen, tipped 

 with white, and the whole plumage exhibited a 

 slight blueish gloss when exposed to a strong light:

 endeavouring to conceal itself from view, and of a 

 dull and heavy appearance. It did not walk, but 

 hopped along in the manner of a crow. The only 

 appearance of liveliness which it exhibited was

 the care of it : at such times it ran forwards with 

 extended wings, opening its bill and uttering a
