Family LANIID^. 



The diagnosis on page 322 will give a general idea of the characters 

 of this family, as represented in the New World, especially as com- 

 pared with its allies the Vireonidae and Ampelidse. The only genus 

 found in America is that of typical " Lanins," and from which I have 

 drawn the famii_^ characters, although as given above they are in 

 general rather those of the Laniinae. 



Enneoctonus, of which Europe has several species, differs in much 

 less rounded wing, the first quill about one-third the longest, the 

 second about equal to the fourth ; the tail shorter than the wing, 

 and much less graduated: the biU more feeble. In the specimen 

 before me of Enneoctonus collurio there is no indication whatever 

 of division of lateral plate of tarsus, and the nostrils are scarcely 

 concealed.
