The species of Galliformes are very numerous. Peters's Check-list of 

 Birds of the World (vol. ii, 1934, pp. 3-141) enumerates no fewer than 

 94 genera, a considerable number of which contain many forms each. 



KEY TO THE SUBORDERS AND SUPERFAMILIES OF GALLIFORMES 



a. Sternum 4-notched, narrower posteriorly than anteriorly. . .suborder Galli (p. 4) 

 b. Sternum with inner notches very deep, extending for more than half length 

 of sternum, outer division of long and narrow posterior lateral process 

 slightly expanded only on outer side, costal process elongated and nearly 

 parallel to long axis of sternum ; hallux relatively small, attached above level 

 of anterior toes, its basal phalanx much shorter than that of toe. 



superfamily Cracoidea (p. 4) 

 66. Sternum with inner notches relatively short, extending for less than half 

 length of sternum, the outer division of the short and broad posterior lateral 

 process widely expanded terminally on both sides, the costal process short 

 with anterior edge at right angle with long axis of sternum ; hallux relatively 

 large, attached at same level as anterior toes, its basal phalanx as long as 



that of the third toe superfamily Phasianoidea (p. 62) 



aa. Sternum 2-notched, wider posteriorly than anteriorly.
