        摘要：Studies on the marine flora of the China coast region of the Western Yellow Sea, including the Po-hai (Gulf of Pe-chi-Li), were first made by the German naturalist G. v. Martens who published in 1866 the first list of marine algae of Yentai (Chefoo) enumerating 17 species. Since then 44 additional papers dealing with the benthic marine algae of this region have been published. A critical evaluation of the records as appearing in these 45 papers has been made. It was found that in the earlier papers, a rather low percentage of the records can be accepted with certainty. For instance, among the 17 records of Martens (1866) only 7 or approximately 41 % of the total number of species, and among the 18 records of Debeaux (1875) only 6 or about 33% can be accepted. From 1866 to 1949, 24 papers have been published, and a critical studies of the records resulted in accepting 129 species and rejecting 38 species, with 15 species remaining to be verified. Since 1949, 21 papers have appeared. Critical studies of the records reported in these papers added 56 species to the marine flora of this region, and rejected 2 species, with 6 species remaining to be verified. All together, there are now 185 species of benthic marine algae reported from the Western Yellow Sea and accepted by the present authors, including 26 green, 47 brown, 35 blue-green and 77 red algae. A check list of these species has been presented and their occurrence in various places on the Western Yellow Sea coast noted, together with the literature involved. Of the remaining recorded species, 39 have been rejected and 21 are awaiting further varification.

        摘要：Very young sporophytes of Laminaria were used in this experiment. From the present experiment the following observations were made: 1. The high dose of 10,000 r of Co60γ-radiations did not cause any immediate death of the sporophyte cells. Death occurred as usual in the next day after γ－irradiation. 2. The young sporophytes which are diploids seem to possess higher radio-resistance to Co60γ-radiations than do the female gametophytes which are haploids. 3. Both the lower and higher doses of Co60γ-radiations all showed some stimulating effects on the young sporophytes. The lower doses seem to have quickened the rate of cell division, while the higher dose of 10,000 r seems to have made the cell swell in the cytoplasm and this eventually caused the death of the sporophytes.

        摘要：Since 1958, we have been carrying out a systematic study of the radiolarian fauna of our seas. Materials were collected during 1958-1959 and in 1961 from the shelf regions of the East China Sea between latitudes 28°-34°N., longitudes 122°-124°E. In the present paper, the first part of such a study described and illustrated 30 species of Acantharia. With the exception of Acanthometra pellucida all are first records for this part of the East China Sea. Of these, two are new species, and two are indeterminable, while two nominal species are changed in their generic combination, viz., Echinaspis echinoides Haeckel transferred to Stauraspis, Thoracapsis elegans var. callosa Popofsky to Dorataspis.

        摘要：Rhizoplecta trithyris Frenguelli, un fossile proprement dit au terrain tertiaire d’Amérique du sud, a étéconsidéré par Frenguelli (1940) comme une espèce de Silicoflagellata. Dans le Traité de Zoologie, Deflandre (1953) a noté que “ le genre Rhizoplecta, dont la position systématique est problématique, mais qui semble débuter par un spicule triaxone, . . . . . . . . . . sans exclure la possibilité d’y voir un Radiolaire plectoide.” Depuis 1958, nous avons collectionné beaucoup de spécimens, qui vivent encore dans la Mer Est de la Chine. Ces spécimens ont des figures semblables à Rhizoplecta trithyris Frenguelli. Le squelette est constitué par un trépied à 3 spicules primaires, réunies ensemble au centre. Chaque spicule avec 2 apophyses opposées s’est réuni en un annelet de triangle arrondi, orné de 3 spicules secondaires disposés alternativement entre les 3 spicules primaires. Sur cet annelet, il existe en outre 4 batonnets qui se dressent un peu perpendiculairement. Les petites branches des spicules et des batonnets se sont anastomosées par arches entre elles en une coque buissonnante. Dans les individus jeunes, la capsule centrale, sur le trépied, a la forme d ’un sphéroide, qui se divisé suivant l'age en 3, 4, ou même en 5 lobes. Par conséquant, c’est surement un Radiolaire plectoide.

        摘要：The present paper deals with 29 species of Cardiid Molluscans collected from the littoral and sublittoral zones of the China Seas, of which 11 species are recorded for the first time from Chinese waters. Six other species recorded previously by different authors from this particular region are not represented in the present collection.
