MARINE BIOLOGICAL STATION AT PORT ERIN. 49 



and the progress of work in the Aquarium. Mr. Chadwick also 

 started the practice of taking meteorological observations, 

 including the temperatures of sea and air, twice daily. These 

 records, continued now over a period of twenty-two years, 

 ought to be of great interest and probably some scientific value 

 in relation to variations of the marine fauna. 



The large red buoy that marks the end of the breakwater 

 at the mouth of Port Erin Bay, and which is moored in a depth 

 of about five fathoms, was carefully scraped in the summer of 

 1898 when brought ashore for its annual cleaning, and that 

 process has been repeated on many occasions since with 

 excellent zoological results. On that first occasion it may be 

 noted that the assemblage of animals, amounting to over 

 30 species, was as follows : — Sycon compressum, Bougainvillia 

 ramosa, Coryne sp., Tubularia larynx, Eudendrium ramosum, 

 Obelia geniculates, Clytia johnstoni, Sertularella rugosa, Nereis 

 sp., Terebella sp., Sabella sp., a Nemertine, Bicellaria ciliata, 

 Scrupocellaria sp., Membranipora membranacea, several Amphi- 

 pods and Isopods, Nymphon gracile, Doto fragilis, Ciona 

 intestinalis (very abundant), Ascidia mentula, Styela grossularia 

 (abundant), Corella parallelogramma, and at least half-a-dozen 

 undetermined species ; while during the recent summer (1919) 

 the species obtained on a similar occasion when we scraped 

 the yacht moorings, close to the buoy, were as follows : — 

 Leucosolenia sp., Sycandra ciliata, Sagartia sp., Obelia geniculata, 

 Eucratea chelata, Membranipora membranacea, Lepralia sp. 

 Canda reptans, Polynoe sp., Nereis sp., Sabella pavonia, Spirorbi 

 sp., Virbius varians, Hippolyte sp., My sis sp., Galathea sp., 

 Idothea baltica, Caprella linearis, Jassa falcata, Dexamine 

 spinosa, Gammarus locusta, Hyas araneus, Phoxichilidium 

 femoratum, Pecten opercularis (young), Anomia ephippium, 

 Saxicava rugosa, Eolis drummondi, E. farrani, Doto fragilis, 

 Hydrobia ulvce, Helcion pellucidum, Ciona intestinalis, Ascidia
