 CHECK LIST 



The two-letter abbreviations used by the postal services are 

 used for states and provinces. A change in this system has been to 

 place a period after the abbreviations of the Canadian provinces. 

 This was deemed necessary because the same letters are used for 

 Nebraska (NB) and New Brunswick (NB.). Also, a period is placed 

 after the last locality listed for each species. In the cases 

 where only one state or province is used the locality is spelled 

 out. 



Synonyms listed are those since 1944. 



Abbreviations used: 



States (Cont.)
