摘要:In the second insta1lment on :Xisha Islands Sargassaceae, six more species were described, inc1uding four new species and two newly recorded for this South China Sea region.
摘要:The present paper deals with descriptions of ten species of marine red algae, including one new species, from Xisha Is1ands. A critical comparative study has been made of various species of Wrangelia Three new sections of the genus Wrangelia are proposed on the basis of various types of cortex. The tetrasporangia of Wrangelia tagoi (Okam.) Okam. et Segawa and Tolypiocladia glomerulata(Ag.)Schmitz as well as the spermatangia of Vanvoorstia coccinea J. Ag. are new1y described.
The specimens studied including the type specimens are all deposited in the herbarium of the Institute of Oceanology,Academia Sinica at Qingdao.
摘要:The present paper deals with the Genus Pyrocystis collected from Zhongsha. and Xisha Islands including their adjacent waters during the periods of May to June in 1974 and March to April in 1975.
There are so far many disputes about the generic diagnosis of Pyrocystis.According to Taylor's opinion, the species which reproduce Gonyaulax-like swarmer and the species, whose life-history was not fully known (such as P. robusta Kofoid etc.) are included in the Genus Pyrocystis. We have identified 5 species, 1 variety and 1 forma, of which all are recorded for the first time from China.
摘要:,The present report is a part of the results of our. investigation on the Pelagic polychaetes of the South China Sea. Specimens were collected by the South China Sea Institute of Oceanology, Academia Sinica and Institute of Oceanology,Acade mia Sinica with plankton net in March to June 1975 from the Xisha Islands 一一-a group of South China Sea coral islands located about 170 miles southeast from Yulingkang of the Hainan Island. Twelve species were identified belonging to 8 genera in 4.families, of which 9 species (with asterisk) are recorded for the first time f'rom Chinese waters.
摘要:The present paper is the report, on the Portunidae of the Xisha Island. It comprises 15 species belonging to 5 genera, illc1uding 1 new species and 5 new record (marked with asterisk) from China.
摘要:The present paper deals with the Cypraeacea (Prosobranchia) collected from the Xisha Islands by the Institute of Oceanology,Academia Sinica, during May-July 1975.Ten species belonging to 2 families and 7 genera are identified. Of these, 2 species (marked with asterisk) are recorded for the first time from Chinese waters.
摘要:This is the second part of our study on the foraminiferal fauna of the Xisha Islands. The material upon which this study is based come from three batches of 56 samples collected during the years 1974-1976 from eighteen islands representing diverse environments;The majority of the samples. were collected from the littoral zone while a few were collected underwater ranging in depths of from a few meters to fifty meters. A total of 235 species belonging to 38 families and 110 genera is added to the previously recorded 175 species. Eight genera and 86 species are considered as new. There is a marked increase in members of the superfamilies Nodosariacea, Buliminacea and Spirillinacea,as a result of, which calcareous perforate species amounted to 66.4%. The calcareous imperforate species although not .as predominant as in the first batch of samples collected in 1957, still make up 20.4%. The remaining 13.2% is made up of arenaceous-agglutinated species.
It is to be expected that with continued and more extensive collections from new localities and with the acquisition of more underwater samples of various depths, many more species are to be added to the foraminiferal fauna of these islands.
