SUBORDER HERODIL HERONS AND BOATBILLS. 



The Herodii contain two families, distinguished by the follow- 

 characters : 



a. 1 Bill lance- shaped, or compressed, narrow, and pointed, its lateral outlines nearly 

 straight, the gonys several times longer than the width of the under mandi- 

 ble Ardeidse. 



a. 2 Bill shaped like a broad inverted boat; its lateral outlines much bowed, and the gonys 

 not longer than width of under mandible Coehleariidae, 



The Cochleariidce are not represented in our fauna, being 

 peculiar to tropical America.
