ANNOTATED LIST OF THE SPECIES 
With some exceptions the following pages do not present full bibliographies 
or full synonymies of the genera and species. Reference is made, however, to the 
papers under the following categories: 
1. original descriptions of the genera and species 
2. principal changes in name 
3. the more comprehensive works and monographs 
4. those especially pertinent to the area. 
The accession numbers used here are those of the Indiana University Museum, 
and retained by the Museum of the California Academy of Sciences, the institution 
to which the Jordan and Eigenmann collections were sold in 1929. Their removal 
from Bloomington to Golden Gate Park constitutes not only an epoch in ichthyo- 
logical history, but a most noteworthy accomplishment in the technique of handling 
and transporting a large collection.
