MARINE BIOLOGICAL STATION AT PORT ERIN. 81 
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 Solecurtus 
antiquatus, Bulla utriculus, Cyclostrema cutlerianum, and 
C. nitens, Odostomia warrent and Defrancia teres from 
off Port Erin; and Mya binghami, Homalogyra rota, 
Odostoma nivosa, and O. 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. I.). He 
succeeded in getting a number of the rarer forms amongst 
which may be recorded Defrancia leufroyi, and Fusus 
antiquus, var. despectus. Mr. Heathcote also reports to 
me Utriculus hyalinus, 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 Reniera rosea, Bowerb. (from 
Fleswick Bay and Perwick Bay), and the crab Pirimela 
denticulata, Leach, (off Spanish Head, 15 fms.). Reniera 
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 Renierid 
sponges, and approaches therefore the Chalinide. The 
only other sponge new to the district reported by Dr. 
Hanitsch is the Desmacidonid Halichondria (Amphilec- 
tus) 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
