UNDULATED HORNBILL. ^7 



lower mandible, the orbits of the eyes, and the 

 space immediately between them and the upper 

 mandible are covered by a bare skin of a blueish 

 colour: the bill is of a yellowish white colour, 

 tinged with pale brown towards the base: its size, 

 as before observed, is but moderate for a bird of 

 tliis genus: it is moderately curved, sharp-pointed, 

 and exhibits hardly any appearance of serratures 

 on the edges: the crest or appendix on the upper 

 mandible is continued about half v^ay along the 

 beak, and is about five or six lines only in height 

 at its highest part: it is also marked on each side 

 by four or five deep perpendicular furrows or un- 

 dulations; thus causing the appearance of so many 

 alternate depressions and projections. This bird 

 is described by Monsr. Levaillant, from a specimen 

 in the collection of Mr. Temmink of Amsterdam, 

 who received it from Batavia, accompanied by its 

 female, which differs only in being somewhat small- 

 er, and is destitute of the reddish-brown patch 

 between the shoulders. Nothing seems to be know n 

 of its particular residence, manners, or history.
