Family, LANIAD^. 



By the analogy which exists betAveen the Ceblepyrince and the Grallatores, the singular 

 fleshy lobes on the bill of C. lobatus and of other species is at once illustrated. We find 

 appendages precisely similar in the Spur-winged Plovers of New Holland and India. Nay, 

 so beautifully and regularly has Nature preserved these relations, that if the Charadriadce 

 really form the Tenuirostral division of the Grallatores, then the Ceblepyrince, occupying pre- 

 cisely the same relative station in the circle of the Laniadce, actually represent the Chara- 

 driadce ; in other words, both these groups, being the farthest removed from their respective 

 types, become parallel to each other, and mutually represent the Tenuirostres. These lobated 

 Caterpillar-catchers constitute, according to our views, the sub-typical genus, which requires 

 to be defined and named ; but we have not, at present, sufficient space to give the necessary 

 reasons for this projected arrangement. 



TYRANNIN^l. 



That these obscurely known Tyrant Fly-catchers, so difficult to define by descriptions, may 

 be better understood by figures, we here add the woodcuts of their heads, accurately drawn 

 the size of life. The size of the bill in 



TYRANNUS BOREALIS, 



and the strongly defined notch of the upper mandible, will bring this species within the limits 

 of the typical group ; although, from the greater quills not being distinctly notched on their 

 inner margin, it bears a very close affinity to Tyrannula Saya. In
