NOTE 



The foregoing index comprises only the names in the Key, not all tho.se in the 

 Cyclopedia. It is not intended that tlie Key shall include every small or incidental 

 generic entry or paragraph in the volumes, for that would make it more involved and 

 complicated. (See page 79.) At the end of some of the families the names of other 

 genera are sometime.s given, so far as these small entries were positively determined 

 when the Key was made, for the purpose of aiding the student to a completer knowl- 

 edge of the family or of advising him of entries that he might overlook. In the progress 

 of the work, other minor or outlying or very recently introduced genera will undoubtedly 

 be inserted, and such new definitions of genera may be made as will necessitate some 

 shifting of names. All such additional entries will be accounted for, under their proper 

 famihes, in the General Index at the close of Vol. VI.
