INDEX OF SPECIES. 



Volumes I. and IL 



Names of varieties are printed as species. The numbers refer 

 to the volume and page. The gender of each genus and subgenus 

 is indicated by the letters m (masculine), f (feminine), or n (neu- 

 ter). When a species name of adjective form is followed by two 

 or more genera or subgenera of differing gender, there are placed 

 after it the appropriate endings in the order — masculine, feminine 

 and neuter. Names of genera, subgenera and species regarded as 

 synonyms are, when possible, printed in italics.
