INDEX. 



All names of species, subspecies, genera and higher grou])s, as avoII as 

 Englisli names, whether they occur in the List proper, Hypothetical List, 

 Fossil List, or Summary of Changes, are indexed. In the case of trinomials 

 both the specific and subspecific names are entered if they differ but not if 

 they are identical, i.e., Branta canadensis canadensis appears as ' ' canaden- 

 sis, Branta" but not with the additional entry "canadensis, Branta cana- 

 densis." In the case of English names all are indexed exactly as they 

 appear in the Check-List while an additional entry is made wherever it 

 has seemed necessary, i.e., in addition to ' ' Eastern and Western Sparrow 

 Hawk " " Sparrow Hawk ' ' also appears ; all three of course under ' ' Hawk, ' ' 

 while a name like "Malhird" is also entered under "Duck" where it 

 might naturally be looked for.
