MARINE BIOLOGICAL STATION AT PORT ERIN. 201 



He obtained the specimens during a series of dredgings 

 along the coasts of the northern parts of the Isle of Man, 

 between Laxey and The Dhoon in the summers of 1890 

 and 1891, chiefly on the site of an old oyster bed, from 

 which in the time of Edward Forbes (1838) oysters were 

 brought to market. The supply of oysters has long since 

 been exhausted, but various large mollusca are still abun- 

 dant, such as Fecten opercularis, Cyprina islanclica and 

 Mytilus edulis. On these, Polyzoa and other encrusting 

 colonies are abundant, and many Crustacea and some 

 Echinodermata, such as Solaster endeca, Palmipes mem- 

 hranaceiis and Astropecten irregulare, are brought up in 

 the dredge. Mr. Wood's hsts contain Palmicellaria 

 skenei, Sccdpellum vulgare, Pisa gihhsii and Chiton han- 

 leyi, new to the district, and Sitberites ficus, Chalina 

 oculata, Polymastia majiimilaris, Flustra securifrons, 

 Lichenopora verrucaria, Cardium nodosum and Tellina 

 donacina, all new to the Isle of Man. This does not 

 exhaust Mr. Wood's work, as he has still undetermined 

 material on hand. As is noted elsewhere Mr. Wood is 

 presenting his collection of named and mounted Manx 

 Invertebrata to the Aquarium at the Biological Station. 



During his visit to Port Erin in April Mr. W. I. Beau- 

 mont worked for some time at the identification and vari- 

 ation of the Nemertida, while later in the summer Mr. J. 

 Henry Vanstone, the Curator of the Station, also occupied 

 some of his time with the determination of the Nemer- 

 tines of the shore. Both these gentlemen have sent me 

 reports upon their work, and I propose that these should 

 be combined to form a joint report by Messrs. Beaumont 

 and Vanstone, which will appear as a separate paper in 

 the Transactions of the Biological Society, and later in the 

 next volume of the " Fauna." Mr. Beaumont found eight 

 species, as follows : — Carinella annulata, Amphiporus
