During the year 1883 the late Pierre Loui.s Jouy, then an assistant to 

 the U. S. National Museum, visited Japan, making a small but very 

 valuable collection of rare forms of lishes, many of which he ol)tained 

 from the markets of Yokohama. During 1885, on his way to Korea, 

 he also visited Sasuna, the port of the Japanese island of Tsushima, 

 in the Sti'aits of Korea. 



In the present paper is given a list of the species collected in 1883 

 and 188.5, with descriptions of new ones, accompanied by plates drawn 

 hj Mr. William Sackston Atkinson, Miss Lydia M. Hart, and Mrs. 

 Chloe Leslie Starks. A few Japanese lishes from other sources con- 

 tained in the U. S. National Museum are also mentioned. Com- 

 parisons have been made with specimens in the very large Japanese 

 collections, as yet undescribed, made by the writers in 1900. The 

 specimens mentioned are in the U. S. National Museum, a few dupli- 

 cates being retained for the museum of Stanford University. The 

 writers are under obligation to Mr, Richard Rathbun and to Mr. Bar- 

 ton A. Bean for many favors in connection with the study of this 

 collection. 



MEASUREMENTS. 



The measurements given in the tables were made by means of 

 dividers and a proportional scale. In some cases the}^ will be of great 

 value as an aid in discriminating between closely related species. It 

 is believed also that thev will show, in an approximately definite way, 

 some of the variations of certain characters useful in the determina- 

 tion of relationships. 



They are expressed in hundredths of the length of the body, which is 

 measured from the tip of the snout to the end of the last vertebra.
