    The tongue in Wallago attu and Gadusia chapra is conspicuous while in Catla catla and Barbus stigma it is rudimentary. Both the mucous cells and taste buds occur in the mucosa of the tongue of fishes undertaken for study;. with the only difference in the inten sity of taste buds which are more in the tongue of Catla catla and Barbus stigma.
    It may be emphasized that further work is necessary on the histology of the tongue particularly with a view to understanding its musculature.

    Chromis notatus (TEMMINCK et SCHLEGEL) is a common pomacentrid fish of southern Japan.
    The author carried out the artificial insemination of thisfish on July 18, 1957, at Ushima, in Hikari City, Yamaguchi Prefercture, and reared the hatched larvae for about three days.
    The spawning season seems to extend from early July to early September in the vicinity of Hikari City.
    The egg is elliptical in shape, with a bundle of tendrils on one end, measuring 0.55-0.60mm in the short axis and 0.74-0.78mm in the long axis. The yolk is colorless with an alveolar structure containing a single oil-globule, measuring 0.21-0.22mm in diameter. The hatching took placein 58.5-70 hours at the water temperature 25.8-28.0°C (Text Figs. A-K).
    Larva just hatched (L) is 2.21-2.40mm in total length. The mygtome number is 9+18-19=27-28 (vertebral number of this fish is 10+15=25). The melanophores are present on the head, on the yolk, on the intestine and along the ventral margin of the tail part. Several xanthophores are found aroulld the eyes and on the yolk surface. In three days after hatching the larva (M) reached 2.85mm and the yolk was entirely consumed.

    Sebastes pachycephalus nigricans (SCHMIDT) is a viviparous fish.
    On December 8, 1956, a female parent fish kept in the aquarium for 2 days after being caught spawned larvae, at the Mekari Aquarium, in Moji City, Kyushu. The author reared these larvae for about one month in a glass jar, feeding with the brine shrimp nauplii.
    Newiy spawned larvae (Fig. A), measuring 6.9-7.0mm in total length, had aremnant of yolk, and swam freely in the glass jar. The myotome number was 10+16-17=26-27. The pectoral fins were large prvided with 17-18 rays, which were densely pigmented with melanophores showing characteristic black appearance. The melanophores and small orange pigment cells were distributed on the head and trunk.
    In 2 or 3 days after spawning the larva (B) attained 7.15mm in total length and the yolk was entirely consumed.
    In 20 days after spawning the larva (C) measuring 9.75mm in total length reached the end of the post-larval stage. All the fins were well formed with a complete set of rays (D. XIII-12, A. III-6-7, V.I-5, P.16-18). The larva covered with melanophores and orange pigment cells from head to tail. The pectoral fins, ventral fins and the anterior part of dorsal fin were densely covered with melanophores. In addition to melanophores, the pectoral fins are densely distributed with orange pigment cells, effecting in a golden lustre.
    The larvae lived for 28 days in the laboratory.

    Paleatogobius uchidai TAKAGI is a small goby, some 35mm in total length, resembling to the gobies of the Genus Chaenogobius GILL: C. castanea (O'SHAuGHNESSY), C. heptacanthus (HILGENDORF), etc. (Fig. 1). It lives a bottom lif e on sandy mud bottom of estuaries in Kyushu, Japan (Fig. 2).
    The sex-dimorphism is slightly observed in the form of genital papillae.The mature female fish are generally larger than the male. The black nuptial coloration appears in the mature female fish only on the ventral ahd anal fins, just as was reported in the gobies of the Genus Chaenogobius: C. castanea, C. heptacanthus, etc. (KINOSHITA, K. 1936, DÔTU, Y. 1954). The ripe ovary contained two groups of the eggs: the mature yellow one, 0.69-0.89 mm in egg-diameter, and the inmature translucent one, 0.14-0.34mm in diameter.The number of the mature ovarian eggs of one individualwas enumerated as 158-430 in eight specimens with the total legth 27-45 mm (Table 1). The ripe testis is thin and translucent band-form with a small appendant organ at its posterior end (WEISEL, G. F. 194 ). The spawning season seemed to extend from January to March in Fukuoka City and its vicinity. The spawning occurred in the ordinal habitat of the adult, as in the estuary of the River Kanakuzu in Fukuoka City. In the same place Chaenogobius castanea also spawned in same manner (Fig. 2; DÔTU, Y. 1954). The parent fish utilized vacant living holes of a kind of shrimp, Upogebia major DE HAAN, for its spawning room. Openings of the numerous holes were exposed all over the flat at ebb tide. The holes were short vertical ones, about one centimetre in diameter and about twenty centimetres long. The spawned eggs were deposited on the inner wall of the hole about five centimetres deep from the opening. The male parent fish was guarding the eggs in the hole until the eggs hatched out. The number of one brood was enumerated as 114-174 in five cases. The water-temperature at the spawning ground was 9.6-14.5°C in the spawning season. The fertilized egg is demersal and adhesive, with a large perivitelline space and a bundle of adhesive filaments at its basal end. The egg is club-shaped, 2.40 mm in long axis and 0.84 mm in short axis, with a shallow depression circling near the top (Fig. 3, Fig. 4). This egg resembles to that of C. castanea in shape, but smaller.
    The newly hatched larva is 4.3mm in total length (Fig. 5 A). The postlarvae under 10mm in total length were not yet collected. The postiarvae, 10-15mm in total length, were collected with drawing-nets in Fukuoka Bay from May to July (Fig. 5 B C). These larvae supposedly live a swimming life in the bay. The last postlarvae, over 15 mm in total length, were found already entering into the bottom life at the estuary where the adult fish lived (Fig. 2; Fig. 5 D E). The gut-contents of the postlarvae, supposedly carrying a swimming life, consisted chiefly of planktonic Copepods, whereas that of the adult consisted of worms, young fish, and organic detritus (Fig. 5 F).
    The examination of the size-frequency of the collected specimens, over 450 individuals, collected from Fukuoka City and its vicinity shows preliminary that this goby attalns 26-31 mm in total length, and becomes mature in a year; in two years it willattain 31-37mm. The largest specimen examined is a female fish, 52mm in total length.

    Girella punctata GRAY is a common shore fish in Japan, attaining some 500 mm when full grown.
    The author operated artificial insemination of this fish on February 6, 1956, at Urashiri, Nobeoka City, Miyazaki Prefecture, Kyushu, and observed egg development and hatched larvae (Fig.1. a-i).
    The egg is bouyant, transparent, colorless and spherical in shape, measuring 1.01-1.05mm in diameter with a single oil globule measuring 0.23-0.25mm in diameter.
    The egg development is much the same as other pelagic fish eggs.
    Hatching took place in 53-55 hours at the water temperature 16.5-17.2°C, and 60 hours at 11-20°C (mostly 14-17°C).
    No pigment developed in the egg.
    The newly hatched larva was 2.27-2.35mm in total length, the oil globule situated in the posterior part of the yolk. The myotome number is 11+16 or 10+17=27 (vertebral number of this fish is 10+15=25) (g).
    In 1.5 days after hatching the larva attained 2.98-3.01mm in total length, and dendrite melanophores appeared on the yolk surface, and ventral side of the body.
    In 3 days the yolk and oil globule was almost entirely consumed and the larva attained 3.58 mm in total length. The melanophores increased in size and number, and the new ones appeared on the dorsal side above the rectum and the posterior part of the tail. The myotome number is 8+18=26.

    新たに日本産硬骨魚類6種 (マサバ, キハダ, マカジキ, イシダイ, コブダイ, ホテイウオ) の甲状腺を記載し, 更に他の資料を加えて, 硬骨魚類甲状腺の形状や組織構造について議論した。
    1.キハダとマカジキの甲状腺の形態は, 夫々既報のマグロとバショウカジキのそれに似ており, 腹動脈上, 第1, 第2入鰓動脈の分岐部に位置して, 前後両葉より成る緻密な軟塊である。
    この様な形態の甲状腺は, マサバ, マルソウダ, シイラ, ブリ, ヒラマサなどに見られる。
    2.イシダイとコブダイの甲状腺は, 前後両要素の区別が明瞭のまゝ一塊となつており, ホテイウオでは, 完全に一葉から成つている。これ等の事実は, 腹動脈より派生する入鰓動脈の状態に支配されているものと思われる。
    3.体重1kg当りの甲状腺重量は, マサバの9.00mgを最低に, ホテイウオの52.5mgを最大とし, 既報の4種を加えた10種類につき平均すると29.07mgとなる。
    4.本報した6種の魚類中, 機能亢進の甲状腺組織像を示したのはコブダイのみで, 他の5種はいずれも正常の活動状態にあつたと考えられる。塊状の甲状腺を有つ魚類では, 組織像のみによって機能の状態を正しく判断する事は困難である。

    ワキンの産卵直後の卵 (Exp.I) と, 孵化後10日を経た仔魚 (Exp・II) をチオウレアの1/3, 000溶液で褪色時期まで飼育したもの;孵化後10日の仔魚を45日間だけ (Exp.III) 同様処理したもの;及び孵化後55日経た仔魚を55日間 (Exp.IV) 処理したものの発生経過を観察して, 次の如き結果を得た。
    1.チオウレアの処理は, ワキンの生長を著しく阻害するが, 遅延度は, Exp.II>Exp.I>Exp.IV>Exp.III>Controlの順となる。処理魚の体形は貧弱で, フナ型を示さず, 尾椎の下方に彎曲するものも現われる。しかし, Exp.IIIでは, 褪色時までにかなり回復するし, Exp.IVでは, 余り変化が生じない。Exp.Iでは, 高率に三つ尾が発生した。
    2.チオウレア処理魚の体地色は, 黄土~黄褐色となり, フナ色を示さなくなるし, グアニンの沈着も抑えられるので, 恰も透明鱗性の金魚のようになる。
    またチオウレアの処理は, 褪色を抑制する。しかし, Exp.IIIでは体地色も追々正常魚のそれに戻り, 褪色も行なうし, Exp.IVでは, 裡色しても対照魚の如く鮮橙色とならず, 黄橙色である。
    3.Expts.I, II, IVの甲状腺は, 増殖肥大して機能亢進の組織像を示すが, Exp.IIIのそれは, すつかり病的状態から立ち直り, 機能低下に近い像を示していた。

    We tried a preliminary consideration of the newly mingling fishes in eel-culture pond. It is as follows:
    Lateolaborax japonicus, Milio macrocephalus, Clupanodon punctatus, or Carassius auratus were estimated as fishes unfit for the culture. Such species as Liza haematocheila, hakuensis or Aplocheirus latipes were believed as mingling fishes fit for the culture, but these economic values may be questionable.
    Therapon oxyrhynchus and T. jarbua were regarded to be of most excellent species as mingling fishes together with Mugil cephalus.

    I. The comparative analysis of the fiber distribution on the lateral-line of fish is made. And we can find the differentiation among them.
    II. We discuss on the relation between the function of the lateral-line organs and the habits of the fish from the ecological stand point of view.
    Results of our studies lend support to the view that the habit of the fish belonged to the three groups may depend upon the function of eac own hnerve.

    The behaviours of fish in response to the sound stimuli were observed by using the fire-work under the water and by striking the bottom of the cask as the source of sound. It is now made clear that the critical sound-intensity to affect the bahaviours of fish varies from one species to the next, and mackerel, (Scomber japonicus) and horse mackerel (Trachurus japonicus) are rather sensitive fish, but conger eels except Rhyncocymba nystromi nystromi are less sensitive.

    The chromosome of six species of the Gobiidae were investigated in male germ cells through spermatogenesis, with special regard to the chromosomal relationship in closely related species. The chromosome numbers of the species under study and chromosomal formulae are summarized in Table 1.
    The spermatogonial complements of the studied species contain small-sized chromosomes as referred to as m-chromosomes, with the exception of Gobius simils. Each species is characterized by possessing a definite number of such m-chromosomes.
    The reduction of the chromosome number which occur beween Gobius simils and Gobius abei, and between Chaenogobius urotaenia and Chaenogobius isaza seems to be due to the disappearance of the m-chromosomes.

    1. マドジョウとフクドジョウ及びマドジョウとエゾボトケの各組合せの正逆両交配を行い, これらの卵の発生及び稚魚の発育経過を観察し, ドジョウ科魚類中の属を異にした3種類の間に存する類縁関係を考察した.
    2. 各交雑卵の発生速度は, 各対照卵に比し梢遅く, 而も対照卵に比し何れも死卵の出現率高く発生期間中に最も高い死卵率を現わす時期は, 各交雑卵共, 嚢胚期より胚体形成期迄であつた。
    3. 各組合せ各々に就いての孵化率は, マドジョウ♀×フクドジョウ♂で20%, フクドジョウ♀×マドジョウ♂で30%, マドジョウ♀×エゾボトケ♂で60%であり, エゾボトケ♀×マドジョウ♂では何れの組合せとも過熟卵で, 総て孵化する事なく斃死した。マドジョウ♀×フクドジョウ♂及びフクドジョウ♀×マドジョウ♂の組合せより孵化した稚魚の殆んど総ては奇型で, これらの奇型稚魚は孵化後2, 3日にして斃死し, 残りの極く僅かな正常に近い稚魚は孵化後10日より13日の間生残つた。マドジョウ♀×エゾボトケ♂より孵化した稚魚は孵化時正常型をなすものが多く認められた。然しこれちも餌を食べる事が出来ず, 孵化後14日より16日迄の間に総て斃死してしまつた。この様に雑種稚魚は早期に総て死滅してしまつたけれども, 生存中の発育経過に於て, 鰓及び色素胞の発達状態及び筋節数等より父方遺伝因子の影響を受けている事は明かであつた。
    4. マドジョウ♀×エゾボトケ♂より生じた雑種稚魚の組織学的検査によれば, 雑種稚魚の各器官は, これらを構成する細胞の連絡が緊密でなく, 卵黄嚢周囲に水腫を生じ, 特に循環系に.就ては, 孵化後2, 3日より殆んど発達を認める事が出来なかつた。
    5. 以上の実験結果より推察して, これら3種類のドジョウ科魚類中, マドジョウはフクドジヨウよりエゾボトケに近縁関係にあるのではないかと考えた。

    1.この研究により, ドジョウの脳下垂体が同種ドジョウの放卵促進に極めて良好な効果を現わすものである事を明にした。
    2.放卵に使用した雌ドジョウ中, 腹部が充分に膨出し, 而も軟かく, 胸鰭及び排泄孔の周囲に赤味を有するものが熟卵を得るために最も適当していた。
    3. 1個体のドジョウに注入される脳下垂体の量は3個より4個が適当であり, 注射後28℃より30℃迄の水温中で飼育された場合, 良好な放卵成績を収めたものは, 13-14時間後に放卵せしめたもの達であつた。
    4.外観より, 必ずしも放卵に使用する事が適当と思われない様なドジョウも2回の脳下垂体注射により熟卵を放出せしめる事が出来た。然し, これらの卵は発生中に奇型を生ずるものが多く孵化率も極めて悪かつた。

    1.旭川地方に於けるフクドジョウの産卵は4月中旬より5月下旬迄の間に行われ, 産卵場所としては, 大川よりもむしろ下水溝や灌漑溝を選び, 放卵は日没後に行われる様であつた。
    2.卵の発生は人工授精をした卵により観察し, 卵の発生経過時の水温は13°-15℃であつた。卵の直径は1.26mmで卵は沈性附着卵であり, 発生は盤割で, マドジョウと殆んど同様な経過を取り, 約168時間で孵化した。
    3.稚魚は孵化直後4.0mmの体長を有し, 筋節数は23+16=39であつた。孵化後日数を経過するも, マドジョウの如き外鰓を有さず, 黒色々素の出現は孵化後3日で, 卵黄の完全に吸収されるのは孵化後7日を過ぎた稚魚で, この頃より餌料を摂取し始めた。
