THE Hornbills, in general, are very large sized birds, 

 having the front of their enormous bills furnished 

 with what appears to be excrescences or protube- 

 rances- of different sizes and shapes, according to 

 the species. They mostly inhabit tropical India, 

 yet several species occur in Africa, and two or three 

 are mentioned as natives of Senegal ; the present, 

 however, is the only one which has yet come before 

 us from that country. This is one of the smallest 

 of the species, and with three or four others, forms a 

 little group, having the bill destitute of those sin- 

 gular appendages which are found on the more 

 typical species. M. Temminck has bestowed so 

 much care and attention in determining the species 

 of this intricate genus, that we adopt his name for 

 the present species; it was long classed by syste- 

 matists as a variety of their B. nasutus, notwith- 

 standing the authority of Le Yaillant, who long ago 

 pointed out the difference between them.
