The Ilombills, 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 Vaillant, who long ago 
pointed out the difference between them.
