AN INDEX TO THE GENOTYPES, 

 EXPLANATORY. 



The following index includes (1) the name of the species, (2) the 

 name of its author, (3) the name of the genus in which it was origi- 

 nally described, and (4) the name of the genus of wliich it is the 

 genotype. When a species given in the index is a synonym of 

 another genotype, a cross-reference is given to the genotype of which 

 it is a synonym. When a species was originally placed in the genus of 

 which it is the genotype, only one generic name is given. Species 

 placed in subgenera by older writers are cited in the subgenus only.
