14 LIVERPOOL BIOLOGICAL SOCIETY. 
A large area of the sea-bottom between Port Soderick and 
Port St. Mary is apparently covered by masses of Melobesia 
calcarea, and the numerous dead valves of Pectunculus 
glycimeris ; and incrusting Polyzoa are especially abundant 
both upon the nullipore and the shells. Mr. J. Lomas, 
who has charge of the Polyzoa, informs me that amongst a 
number of other rare forms he has identified Stomatopora 
johnstoni,* and S. incrassata,* Tubulipora lobulata, and 
T. flabellaris, Lichenopora hispida, Cellepora dichotoma, 
Membranipora aurita, M. craticula, and M. dumerili, 
Schizoporella unicornis,* Hippothoa flagellum,* Diastopora 
suborbicularis, and a peculiar variety of Cellaria fistulosa. 
Of these, the four species marked with an asterisk are new 
to our fauna. A single valve of Pecten maximus brought 
up in the dredge has been found by Mr. Lomas to be 
incrusted by colonies of no less than eleven species of 
Polyzoa, some of them rare forms; while a dead shell of 
Buccinum undatum similarly affords attachment to nine 
distinct species. 
Towards evening three very successful hauls of the 
dredge were made, which covered practically all the ground 
in a line from the southern end of the ‘‘Calf”’ to the 
northern side of Port Erin Bay, just under Bradda Head. 
Amongst the material obtained in these hauls the fol- 
lowing species were noticed :—Asterias glacialis, Solaster 
endeca, Stichaster roseus, Porana pulvillus, Luidia fragil- 
lissima, Antedon rosaceus, Stenorhynchus longirostris, S. 
phalangium, Inachus dorsettensis, Hyas coarctatus, Hury- 
nome aspera, Xantho rivulosa var. tuberculata, Pinnotheres 
pisum, Ebalia tuberosa, Corystes cassiwwellaunus, Hupagurus 
cuanensis, Anapagurus hyndmanm,* A. levis, Galathea 
intermedia, Munida rondeleti,* Caridion gordoni,* Pandalus 
brevirostris, P. annulicornis, Virbius varians, Pleuro- 
* Those species marked with an asterisk are new to the fauna.
