Java and the Philippine islands ; nor does it appear to be 

 very rare, if we may judge from the number of dried heads 

 in the European collections, though entire specimens of the 

 bird are of very rare occurrence. 



It is quite unnecessary here to recapitulate the species : for 

 a list of them we therefore refer to the preceding part ; to 

 which we shall merely add here figures of two species of these 

 remarkable birds from that highly elegant work the " Planches 

 Coloriees" of M. Temminck. 



The Crested Hornbill, Buceros Cassidix, Tem.,has the bill 

 of a bright yellow, furnished at the base of both mandibles 

 with an additional horny substance, covered with transverse 

 rays ; that on the upper mandible is nearly semicircular, 

 large at the base, forming a cutting edge in front ; its colour 

 is deep purple-red. 



The specimen figured was brought from Celebes by M. 

 Reinwardt, and was a male adult. In what, if any, par- 

 ticular the adult male differs from the female and the young 

 is not known. The top of the head is marron-colour ; the 

 neck is bright golden-yellow ; the body, wings, and thighs 

 are shining metallic black-green, and the tail is perfectly 

 Avhite. The beak is of a brilliant golden-yellow, the base 

 covered with a thick horny bed, transparent, and marked 

 diagonally with three deep black-coloured furrows, the ridges 

 between which are reddish-orange ; round the eyes and the 

 guttural skin are livid yellow, tinted with blue. The total 

 length of this bird is near four feet, and the bill ten 

 inches. 



This species inhabits high woody mountains, and lives 

 principally on fruit. 



To this figure we have added a plate representing the prin- 

 cipal differences to be found in the bills of several of the 

 species of this very extraordinary genus.
