north side of Fleshwick Bay there are some exquisite 

 rock-pools hned with encrusting Nullipores and other sea- 

 weeds, and containing Sponges, Sea-anemones, Zoophytes, 

 Polyzoa, Worms, Nudibranchs, and other animals. The 

 rich green alga Codium tormentosum was obtained in these 

 pools, but, although carefully searched for, no specimens 

 of Elysia viridis were found upon it. 



As the sea was still very rough, the early part of the 

 fourth day was spent on board the ''Hyaena," 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. S. 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
