MARINE BIOLOGICAL STATION ON PUFFIN ISLAND. 59 
north side of Fleshwick Bay there are some exquisite 
rock-pools lined with encrusting Nullipores and other sea- 
weeds, and containing Sponges, Sea-anemones, Zoophytes, 
Polyzoa, Worms, Nudibranchs, and other animals. The 
rich green alga Codiwm tormentosum was obtained in these 
pools, but, although carefully searched for, no specimens 
of Hlysia viridis were found upon it. 
As the sea was still very rough, the early part of the 
fourth day was spent on board the ‘‘ Hyena,” at anchor 
in Port Erin Bay. Tow-nets were let down, both on the 
surface and weighted so as to reach the bottom, and a 
small dredge with a long canvas net was taken out in a 
boat and used for obtaining samples of mud and sand to 
examine for small animals, such as Foraminifera, Copepoda 
and Ostracoda. The strong wind blowing was utilised by 
Captain Young, the representative of the Salvage Asso- 
ciation, who suggested floating tow-nets across the bay 
with lifebuoys, and devised a sailing apparatus, consisting 
of an old lifebuoy rigged up with a mast and sail, and 
having a tow-net suspended from it, which was let out, 
carrying a long line, to leeward, and was then hauled in, 
the net keeping distended and working well during both 
the outward and the return journeys. Another surface net 
was even rigged up attached to a large kite, but this did 
not work satisfactorily. By these various means a large 
amount of material was collected and preserved for future 
examination. Mr. I. C. Thompson and Mr. W. 8S. McMillan, 
who are engaged in working out the Copepoda and Ostracoda 
of Liverpool Bay, have lately been getting some interesting 
species in mud and other deposits from Puffin Island 
and elsewhere, and they predict that it is from such sources 
that the most important additions to our fauna will be 
made in the future. Consequently, Mr. McMillan has 
devised a small dredging tow-net which will bring up
