GROUP OF HORXBILLS. 



Hornbill {Buceros cristatus), and that on the right is the Two-horned Hombill (Buceros 

 hicornis). The smaller species at the bottom is the "Woodpecker Horubill {Buceros Pica). 



Peehaps the greatest development of beak and helmet is found in the Rhinoceros 

 Hornbill, although there are many others which have these appendages of great size, as 

 may be seen by refening to the group of Hombills.
