THE NOMENCLATURE OF AMERICAN FISHES AS 

 AFFECTED BY THE OPINIONS OF THE 

 INTERNATIONAL COMMISSION 

 ON ZOOLOGICAL NOMEN- 

 CLATURE. 



In the third International College of Zoology meet- 

 ing at Leyden, Holland, in 1895, an International Com- 

 mission on Zoological Nomenclature was appointed. At 

 Cambridge in 1898, this Commission was made perma- 

 nent, and the number increased from five to fifteen. At 

 Eerne in 1904, these were divided into three classes, each 

 to serve for nine years. At Boston in 1907, provision 

 was made for giving opinions on problems in zoological 

 nomenclature by vote of the members of the Commission. 



These opinions have been printed from time to time 

 by the Smithsonian Institution. (Publications 1938, 1989, 

 2060, 2169, 2256, 2359.) 



In the present paper I have tried to note the changes 

 in nomenclature of American fishes since the publication 

 of Jordan and Evermann's Fishes of North and Middle 

 America (1898), (Bulletin 47 U. S. National Museum), 

 as affected by these opinions. 



Etheostoma Rafmesque 

 Type Etheostoma blennioides Rafmesque. The gen- 

 eric name Etheostoma should replace Diplesion, for 

 Etheostoma blennioides (Rafmesque), while Catonotus 

 Agassiz should replace Etheostoma as the generic or sub- 

 generic name of the group typified by Etheostoma flabel- 

 lare Rafmesque. If the genus is to be recognized in the 

 broad sense adopted by Jordan and Evermann under the 

 head of Etheostoma, the name Pozcilichthys must be 

 taken instead of Etheostoma, Etheostoma variatum Kirt-
