MARINE BIOLOGICAL STATION AT PORT ERIN. 27 



OTHEE EEPOETS ON WOEK. 



Professor Harvey Gibson writes as follows : — 

 " During the Easter vacation a course on Marine 

 Algse was given at the Station, attended by over twenty 

 advanced students from the Botanical Department of 

 the University, by two students from the University of 

 Birmingham, three from University College, Cork, and 

 one from the University of Cambridge. The course con- 

 sisted in systematic collecting in Port Erin Bay, Port 

 St. Mary, and elsewhere. The plants collected were 

 examined in the laboratory during flood tide, and each 

 evening a short lecture was given on the morphology and 

 life-history of representative forms. In addition to the 

 identification of species already recorded from the 

 district, several new forms were found and material was 

 gathered for subsequent research. It is hoped at an 

 early date to publish in the ' Transactions of the 

 Biological Society ' some notes upon these new species, 

 and on certain morphological points which have not 

 hitherto been described. One hundred and fifty-seven 

 species in all were collected, among which the following 

 are the more important novelties: — 



Chlorophyceae. Phaeophyceae. 



Pranola stipitata. Ectocarpus granulosus. 

 Enieromorpha percursa. „ hincksii. 



Endoderma witrockii. Cladofstephus verticillatus. 



Epicladia flic-strae. Ascocyclws leclancheri. 



Cladophora nuda. Leathe-sia difformix. 



Bryopsis hypnoides. Sporochnus peduncidntits. 



Fucus ceranoides. 



Rhodophyceae. 



Bangia fuscopurpurea. Dilsea edulis. 



Hehninthodadia purpurea. Petrocelis cruenta. 



Calloph.yllis laciniata. Peyssonndia dubyi. 



Catenella opuntia. Hildpiihrnndtia rosea. 



Sphaerococcu-s coronopifolius. RJwdomda lycopodioides. 



Champia parvula. Laurentia obtusa. 



Delesseria hypoglossum. Polysiphonia violacea. 

 Ceramium gracillimum. ,, byssoide-s. 



„ acanthonotum Nemalion multifidum.
