FISHERY BULLETIN OF THE FISH AKD WILDLIFE SERVICE 



taxonomy of the various species of tuna. As the 

 relationsliips of the tuna species of the Pacific, and 

 for that matter the world in general, have not been 

 clearly defined, specific names of questionable 

 validity have been arbitrarily indexed as separate 

 entries. For example, Neothunnus itosibi is re- 

 garded by some workers as a form distinct from 

 Neothunnus 7nacropterus, while others consider 

 the two to be synonymous. References to Neo- 

 thunnus ifosihi and Neothunnus jnacropte/iis, 

 therefore, have been treated separately. Syno- 

 nyms which are generally accepted as applying to 

 one given species, such as Euthynnus pelamis for 

 Katsuioonus pelamis, have been indexed under the 

 name which is believed to have priority, with 

 appropriate cross reference under the synonymous 

 name. The same procedure was used in indexing 

 names which differ slightly in spelling. Again, 

 it should be pointed out that the indexing of these 

 scientific names is to a large degree arbitrary, and 

 is not an attempt to clarify the systematics of the 

 tunas. 



A list of abbreviations of the various publica- 

 tions cited and of the English translations of titles 

 of Japanese periodicals as used in the bibliography 

 is included.
