Intkodugtiok vii 



The known geographic distribution of each species is indicated by 

 superscript figures at the end of the hues, which correspond to geo- 

 graphic regions designated by the same superscript figures. In gen- 

 eral, the distribution is as given by the author of the reference, the 

 country being the smallest unit, except in the case of larger coun- 

 tries, where States and Provinces are considered the smallest units. 

 In the larger island groups the individual islands are indicated 

 wherever possible in view of the importance of island endemism.
