MBMOIES OF THE CAENEGIE MUSEUM. V^OL. VI. NO. 4. RECORD OF THE FISHES OBTAINED IN JAPAN IN 1911. By David Starr Jordan and William Francis Thompson. (Plates XXIV-XLII.)

His naturahst friends in Japan at once began to make collections of fishes for him, at the same time cheerfully assisting him in his efforts to study the fishes in the scant leisure which his other occupations allowed. A large collection was obtained and through the courtesy of Mr. Asano and Mr. Shiraishi of the Toyo Kisen Kaisha delivered without charge in Cahfornia. About three hundred and ninety species were obtained in Japan. This collection which forms the subject of this paper is shared between the Carnegie Museum at Pittsburgh, and Stanford University. The types are in the former institution, as the new species are pub-lished under its auspices. The collection consists of the following: 1. A large collection made by Mr. Alan Owston of Yokohama, covering various localities in Japan, the most valuable materials being dredged by him in his steamer, the " Golden Hind." Many valuable specimens from Mr. Owston's collections were obtained by Jordan and Snyder in 1900. Other new species obtained from him have been described by Mr. Shigeho Tanaka, and by naturalists in Europe. 2. A collection made at Misaki by Mr. Kumakichi Aoki, fisherman at the Seaside Laboratory of the Imperial University of Tokyo, under the direction of 205
