FLOUNDERS AND SOLES FROM JAPAN COLLECTED BY THE UNITED STATES BUREAU OF FISHERIES STEAMER ''ALBATROSS" IN 1906. By Carl L. Hubbs, Of Stanford University, California. INTRODUCTION. The present paper deals with the Heterosomata (flounders and soles) collected during the 1906 expedition of the United States Bureau of Fisheries steamer Albatross in Japan. Nine species are described as new, two representing genera which are apparently un-described. A new generic name is proposed for En^yprosopon iijimae Jordan and Starks, and a rearrangement of several other genera has been found necessary. The flounders and soles obtained during this expedition by members detached to study the shore fishes have been reported on by Prof. J. O. Snyder.^ The writer is indebted to Dr. C. H. Gilbert for opportunity to study this collection and for assist-ance and suggestions in the preparation of this report. He has been materially assisted by a comprehensive review of the flounders and soles of Japan, by Jordan and Starks. ^ Measurements are expressed in hundredths of length from tip of snout to base of caudal, this length being expressed in millimeters. Under each species the stations at which the Albatross obtained the specimens are mentioned, together with the approximate locality. Following is a detailed list of these stations : Abbreviations and symbols. [* Signifies depth as shown by chart when no sounding was made. ** Signifies depth and character of bottom as obtained by sounding at previous station.] The character of bottom is expressed by the following abbreviations: bk black.
