    1.1950年8月から10月までの間、京大瀬戸臨海實験所近海で、30C.P.~100C.P.の水中又は水上燈を用いて操業している棒受網漁船及び一本釣漁船に便乗し集魚燈動物の観察をした。
    2.燈に集まるのは魚類・頭足類・浮游性甲殻類及び底棲動物の一部である。
    3.胃内容の調査・船上の観察及び漁師の話を綜合して集魚燈動物を次の食性段階に分類した。
    (1) 餌料動物
    (2) 第1次捕食魚
    (3) 第2次捕食魚
    (4) 第3次捕食魚
    (5) 第4次捕食魚
    (6) 底層魚
    (7) 独立群
    (8) 最終捕食魚 (魚群破壊魚)
    4.同一食性段階に屡し互に直接の食餌開係を有しないものの間の順位をも考えて、集魚燈動物全体を通じての相互關係を第1圖た表わした。

    The flatfishes of the genus Samariscus are among the rare fishes in Japanese waters and have been known only from KAMOBARA'S several records. Although he reported three species, Samariscus maculatus (GÜNTHER), S. inornatus (LLOYD) and S. jajionicus KAMOHARA (1934: 461; 1936a: 21; 1936b: 1006), he finally recognized the last mentioned two species from Japan (1938: 61).
    Recently, having had an occasion to identify a rather, large number of the specimens of the flatfishes taken from deep-waters around Japan and the adjacent regions by means of motor-trawlers, we were very fortunate enough to find two kinds of specimens of Samariscus which agree well with KAMOHARA'S two species (1938: 61). As a result of detailed examinations of these fishes, however, we have found an evidence to indicate that the one form represents an apparently undescribed species which called herein Samariscus latus and that KAMOHARA'S Samariscus inornatus falls into this species. The other one, Samariscus japonicus, although rather well marked, is somewhat variable as supplemented in this paper.
    The measurements of various parts of body which would appear in the present work were made in exactly the same way as NORMAN had done in his work (1934: 50·51).
    The present study is a part: of the results of our investigations on the deep-water fishes of Japan and the adjacent regions. The expenses f Jr the studies of the present series were defrayed by the research f and by Mr. Keizo SHIBUSAWA from 1943 to 1945 and by the Ministry of Education from 1948 to 1951. We are also greatly indebted to Messrs. Reizo ISHIYAMA and Akira OCHIAI for their assistances rendered in obtaining the material.

    The present new species is based on forty specimens obtained by motor-trawler near the sea-coast of Uozu, south-eastern part of Toyama Bay, at a depth of about 303 meters (200 “hiro”). The measurements were made in the same way as the senior writer had done in his previous studies on the deep-sea fishes of Japan.

    In the above list I have given names and the distribution of all the fishes (721 forms) now known from the Suruga Bay with other related localities.
    The mark × indicates simply the occurence of the species or forms concerned in the region named at top of the column; the mark Δ, that the same is known to be found in the fresh or brackish waters in the region; and the mark Δ, that the same is an endemic species, not recorded from outside of the Suruga Bay.
    Description of No.596.
    Callionymus lunatus form. usuiro, form. nov.
    Characters.-Resembles C. lunatus, but distinguishable from it in having the first dorsal spine with a very long filament, reaching almost the caudal peduncle and adistinct black eye-like spot at the posterior part of the first dorsal fin which is yellow in life. In the female specimen the first dorsal is olivaceous black with oblong or roundish white spots on the membranes from the 1st to the 3rd. General color of the back of the both sexes are much paler, pale greyish, with small spots or lines of pale brown.
    Measurements.-Δ, total length 200, body length 146, length of 1 st dorsal filamoent 76 mm. Δ, total longth 165, body length 129, length of 1st dorsal filament 18.5 mm.
    Type.-An adult male (N. KUROAD C0ll), off Shige, Numazu, Shizuoka Prefecture, Hondo, Japan; collected April 2, 1946, by the author.
    Habitat.-At present, it is only known from Susuga Bay.
    Remarks.-They were obtained from bottoms not so far from the shore, but apparently they are found on deeper bottoms than in the ordinary species, C. lunatus.
