LIST OF FISHES COLLECTED IN 1883 AND 18S5 BY PIERRE LOUIS .lOUY AND PRESERVED IN THE UNITED STATES NATIONAL MUSEUM, WITH DESCRIPTIONS OF SIX NEW SPECIES. By David Stark floKDAN and John Ottekkein Snyder, Of the LeUmd Stanford Junior UiiAva'nitij. 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. Proceedings U. S. National Museum, Vol. XXIII— No. 1235. 739
