The Baltimore Orioles [Xfxnthorms baltimorii, Sw.) have tte 

 bill broad at the base, nearly conical and pointed ; the upper 

 mandible has the dorsal line slightly arched, the ridge narrow, 

 the sides flat and sloping at the base. They are chiefly American

 a kind of purse, about a j^ard in length and a foot in diameter, 

 the mouth or entrance being placed sometimes at the upper 

 extremity, sometimes on the side. Naturalists have subdivided 

 them into many smaller groups or genera, the most important 

 being the one here described, and which may well be taken as 

 an example. They are confined entirely to North America. 



The Beef-eaters [Bvpliagus, Briss.), Fig. 223, owe their name 

 to a singular habit they have of lighting on the backs of rumi- 

 Jiating mammalia, and picking oif the insects or extracting the 

 larvte of CEstri which infest them — an operation which cattle 

 submit to -n'ith great pleasure. Their food is not confined to the
