Order STEGANOPODES. 



Totipalmate Swimmers. 



The birds comprising this order are distinguished from all other 

 swimming birds by the fact that the hind toe is connected with the 

 inner toe by a web, making three webs instead of two, as in the ducks 

 and gulls. The several families are distinguished as follows : 



a. Tip of upper mandible with a distinct hook or "nail" at the tip. 



6. Bill 10-15 long, with large pouch. PELICANS, p. 73 



66. Bill 2-3 long, scarcely any pouch. CORMORANTS, p. 72
