Ml'. K, Nomaguchi, mayor of Yamagawa, as well as to numerous other 

 officials of the various prefectures. 



For assistance and suggestions in studying this collection we 

 acknowledge our indebtedness to Dr. D. S. rlordan, Dr. H. W. Ever- 

 mann, Dr. Theodore Gill, and Mr. Alvin Seale. 



The extensive writings of Dr. David Starr Jordan and his associates 

 descriptive of the iish fauna of Japan have made comparatively easy 

 the identification of this collection. That the waters of Japan still 

 hold many undiscovered ichthj'ological treasures can not be doubted, 

 however, notwithstanding the large amount of matter which has within 

 the past few years been added to the already ver}- considerable litera- 

 ture of Japanese fishes; for the present collection, made quite inci- 

 dentally, limited to specimens most easil}" preserved, and representing 

 little more than the forms found here and there in the markets, con- 

 tains one new family (CaristiidaB), five new genera, and eleven new 

 species, in addition to several species not previously known from Japan. 

 In this last class are EnthoUehtJiy.s //ntsukur/'l (Jordan and P^vermann), 

 described from Formosa; Nealotus tripes Johnson, not previously 

 known froiu the Pacific Ocean; Terapon jarhua {Vox^^\ Peristedion 

 rieffel't Kaup; and Ehoti'iodes heldsdingenii Bleeker. 



The local names of the fishes in the localities where collecting was 

 done have been supplied wherever known.
