MAEINE BIOLOGICAL STATION AT TORT ERIN. 37 



deal of material which he had collected at Puffin Island 

 last year, reports to me that he has fifteen species of 

 Lamellibranchs and Gastropods to add to our records : of 

 these 8 are from Bay Fine and the immediate neighbour- 

 hood of Port Erin, and 7 from Puffin Island. Among the 

 more noteworthy of these, collected and identified by Mr. 

 Leicester and Dr. Chaster of Southport, are Soleciirtus 

 antiquatiis, Bulla utricidus, Gyclostrema cutlerianum, and 

 C. nitens, Oclostomia loarreni and Defrancia teres from 

 off Port Erin ; and My a hinglmmi, Homalogyra rota, 

 Odostomia nivosa, and 0. turrita from Puffin Island. 

 Mr. W. H. Heathcote, of Preston, who spent some time 

 at the Biological Station in July, was chiefly engaged in 

 dredging for Mollusca about Bay Fine (see PL L). He 

 succeeded in getting a number of the rarer forms amongst 

 which may be recorded Defrancia leufroyi, and Fusus 

 antiquics, var. clespectus. Mr. Heathcote also reports to 

 me Utricidus hyaliniis, Turt., cast up at Southport, new 

 to the district. 



During September Mr. A. Chopin, of Manchester, 

 carried on some dredging from Port St. Mary and Port 

 Erin, and was able to add at least two species new to our 

 records, viz. the sponge Beniera rosea, Bowerb. (from 

 Fleswick Bay and Berwick Bay), and the crab Pirimela 

 denticulata, Leach, (off Spanish Head, 15 fms.). Beniera 

 rosea was recorded by Bowerbank from Tenby and Sark. 

 Dr. Hanitsch informs me that this species seems to have 

 a larger amount of " spongin " than most other Kenierid 

 sponges, and approaches therefore the Chalinidae. The 

 only other sponge new to the district reported by Dr. 

 Hanitsch is the Desmacidouid HalicJiondria {Aviphilec- 

 tits) expansa, B., dredged on September 24th off Clay Head. 

 It had previously been obtained only at Skye, by Dr. A. 

 M. Norman. The specimens of Spongelia fragilis which
