tomlin: notes on .afarine mollusca of north wat.es. 29 



Venus gnidia Brod. They were dredged on an oyster-bed 

 in a few fathoms in Rhoscolyn Bay, south of Holyhead. 



Trophon muricatus Mtg. — One at Bull Bay (IvA.). 

 Trophon truncatus Str. — Alive at Bull Bay (F.A.). 

 Fusus antiquus var. alba Jeff. — This gigantic form occurs 



off Anglesea, but though I have it thence I cannot specify 



exact locaHty. 

 Fusus propinquus Alder. — Thrown up at Llandulas (F.A.). 



Actaeon tornatilis L. — A specimen from the Dovey measures 

 an inch in length. The var. stilntlata Wood also occurs 

 there. 



A few records of the Nudibranchs and Cephalopods that 

 have been collected on the coast hitherto may prove interesting. 

 The list is complete as far as I can ascertain. Hilbre Island, 

 at the mouth of the Dee and just outside the limits, is very rich 

 in the Nudibranchiata and produces several great rarities. The 

 letter 'L' appended to the following Records denotes that they 

 are cited from Reports I. and II. of the Liverpool Marine Bio- 

 logical Committee, published in 18S6 and 1889.
