It is also here that we must place 



The Beef-eaters. (Buphaga Briss.) 



A small genus, whose bill, of moderate length, at 

 first cylindrical, swells at the two mandibles, before 

 its extremity, which terminates in rather a blunt 

 point. It enables the birds to compress the skin of 

 oxen, to force out the larvae of the oestruSy which lodge 

 there, and on which these birds feed.
