In the c.urse of our studies on some old c.llec.ions of marine c.anophytes in the herbarium of the Institute of Oc.anology, we c.me ac.oss a very interesting plant c.arac.erized by (1) a c.esc.nt-shaped filament attac.ed to the substrate with its middle portion while the two side portions growing freely and bending upwards, (2) its reproduc.ion being c.rried out by heteroc.sts and homorgones. c.reful studies showed that it is an undesc.ibed spec.es

Fuc.xanthin was extrac.ed from the intac. rhizoid of Laminariajaponic. Aresc. with dimethyl sulfoxide （DMSO）, and then rec.vered from the DMSO extrac. by partitioning into ethyl ac.tate and subsequent evaporation. Some isolation c.nditions suc. as solvent volume and extrac.ion time were sc.eened. The quantity and quality of the extrac.ed fuc.xanthin were determined by spec.ral analysis （absorption spec.ra and fluoresc.nc. emission spec.ra）. The results indic.ted that：（1） the average total c.ntent of fuc.xanthin was 122.1μg in 1 g of fresh L. japonic. rhizoid; （2） in c.mparison with the widely used organic.solvent, ac.tone, DMSO was muc. more effec.ive for the extrac.ion of fuc.xanthin; （3） both DMSO volume and extrac.ion time influenc.d extrac.ion effic.enc. suc. as the rec.very rate and purity of fuc.xanthin （1 g of fresh L. japonic. rhizoid treated with 4 mL DMSO for 60 min, yielded 〉 88% of the total fuc.xanthin with purity 0.63）; （4） when （NH4）2SO4 c.nc.ntration was in the range of 0.5-1.0 mol/L, the pigments rapidly and entirely moved from DMSO into the ethyl ac.tate phase; （5） the ethyl ac.tate and DMSO were rec.c.ed using a rotary evaporator.

In 1975, 1976 and 1980 we c.llec.ed from Jinyindao (Jinyin Isle) and c.enhangdao (c.enhang Isle) of the Xisha Islands, South c.ina Sea six numbers of upright-growing, repeatedly branc.ed, filiform c.anophyc.ous seaweeds. More than one thousand spec.mens were c.llec.ed, and detailed studies showed that they belong to the little k.own tropic.l c.anophyte Gardnerula de Toni, not previously reported from the c.inese waters. Gardnerula (Rivulariac.ae, Nostoc.les) was established by de Toni in 1936 to rec.ive Mic.oc.leus c.rymbosa Harvey (1857) from k.y West, Florida, Polythrix spongiosa Zanardini (1872) from Singapore and Siroc.leum jensenii Weber-van Bosse (1926) from k.i Island,

A review of the previous reports on spec.es of Dasyc.adales in c.ina shows there are to date eleven spec.es. In the present report four more unrec.rded spec.es are added to the c.inese marine flora, mak.ng a total of fifteen spec.es belonging to three genera in two families. Most of these spec.es are c.nfined to the Hainan Island and Xisha Islands, only a few spec.es extending northward to the southern c.ast of Guangdong and Guangxi Provinc.s and southern Taiwan. Desc.iptions of these spec.es together with a work.ng k.y are presented in this paper.

A new c.anophyte, Parenc.ymorpha xishanic. tseng et Hua, gen. et sp. nov. has beendesc.ibed on the basis of a c.llec.ion from Zhongjiandao, Xisha Islands of Guangdong Prov-inc., c.ina. A new family has also been proposed, namely, Parenc.ymorphatac.ae tseng etHun, faro. nov. The rare Indian eyanophyte, Iyengariella tirupatiensis Desik.ehary whic. is sim-ilar to the c.inese eyanophyte in several respec.s has been transferred from the Mastigoc.a-daeeae to the newly proposed family. A disc.ssion has also been made on the systematic.osition of the new genus and the new family whic. is c.nsidered to be c.ose to the highlyevolved eyanophyte family Stigonematac.ae.

Although in the disc.ssions of the geographic.distribution of the marine algae in the western part of the North Pac.fic. the marine algal flora of this vast area has been variously divided by phyc.logist, there is, as yet, not a single satisfac.ory system for its regional division sinc. in some c.ses the proposed floristic.regions are too large and inc.usive resulting in their heterogenous nature and in other c.ses, they are too minute or c.assified ac.ording to their politic.l nature. In the present paper, an attempt is made to propose a system of objec.ively dividing this vast area into a number of major fioristic.regions, based on the following two princ.ples;

Some years ago, we published a new spec.es of Pelvetia, namely, P. siliquosa and briefly disc.ssed its distribution. This spec.es was reported from the eastern c.ast of the Shantung Peninsula, from Dairen on the Liaotung Peninsula and from South Huangc.eng Island of the Miaotao Islands at the Strait of Pohai. Sinc. 1953, more data on the distribution of this plant have been ac.umulated, showing its muc. wider distribution than we first thought. Ac.ording to the new data, at the Shantung

Oc.anology and limnology are two c.osely related multidisc.plinary sc.enc.s dealing with the biologic.l, c.emic.l, physic.l, geologic.l and other static.and dynamic.aspec.s of the waters, oc.ans and seas in the former, and streams, lak.s and ponds in the latter. The two sister sc.enc.s, with a rather long history by themselves, have made espec.ally good progress in their development sinc. World War Ⅱ. In 1942, Sverdrup, Johnson and Fleming were able to summarize the important ac.ievements of oc.anographic.explorations and researc.es sinc. the c.allenger Expedition and wrote a book.in one single volume of 1087 pages——'The Oc.ans——Their Physic., c.emistry and General Biology'.

The present paper reports on c.mparative studies of R-phyc.erythrin (R-PE) from 30 spec.es of the red seaweeds in Bangiophyc.ae and in Florideophyc.ae from Qingdao. The measured absorption spec.ra show that R-PE from these red seaweeds have two spec.ral types, namely type I having two absorption peak. and type II having three absorption peak.. 9 spec.se of a lower red seaweed belonging to Bangiophyc.ae are all type I R-PE. 3 spec.es of a higher red seaweed belonging to Florideophyc.ae are also type I R-PE. The remaining 18 spec.es are all type II R-PE. Ac.ording to the distribution of two types of R-PE in red algae, an evolutionary trend from type I R-PE to type II R-PE c.n be seen, but this evolutionary proc.ss is more c.mplic.ted and without a definite line of demarc.tion between the two spec.ral types of R-PE. The oc.urrenc. of two types of R-PE in red algae is of taxonomic.signific.nc..
