of the North of Ireland. 99 



on all kinds of ground and at all depths, from half -tide down to 100 fathoms, 

 the limit of the British fauna. 



var. littoralis. Carrickfergus— Belf. Mus. Coll. It is prohably common. 



var. striata. Living in 60 fathoms about 6 miles from the Maidens — Hynd- 

 man. 



[Buccinum cyaneum. 



" A fragment only, considered by Mr. Jeffreys to be this species, inTurbot 

 Bank sand, Mr. "Waller " — Hyndman, 1858 Report. I have failed to trace 

 this species to a modern synonym ; it is probably some glacial fossil.] 



IWCurex erinaceus, Linne. 



" Of general occurrence " — Thompson {Triton erinaceus). Jeffreys, after 

 giving a list of British stations, remarks "all the specimens procured from 

 the northern coasts were dead ;" and this remark applies to our province, for, 

 though it is of frequent occurrence on the shore, and in depths up to 30 

 fathoms, I iind no note of its having been taken alive.* 



Tropiion muricatus, Montagu. 



Hyndman dredged it alive on the Cod Bank off Larne (20 fathoms), and 

 also in 25 fathoms off Black Head, but very sparingly ; and took it rather 

 commonly in a dead state off Donaghadee, and on the Turbot Bank, and in 

 70-100 fathoms near the Maidens. From Dickie's Report, dead shells appear 

 to be distributed throughout Strangford Lough and the channel adjacent. 

 Jeffreys queries these and other northern records, and considers that they are 

 probably referable to T. Barvicensis. The present species has its head- 

 quarters in Lusitanian and Mediterranean waters, and does not range north of 

 Britain. 



Trophon Barvicensis, Johnston. 



Hyndman obtained it living with the last in the two stations mentioned, 

 and dead in 8-10 fathoms in Belfast Lough, and on the Turbot Bank. 

 Dickie dredged a few dead specimens in 12-15 fathoms outside Strangford 

 Lough. This is a northern form, ranging to the arctic seas, and not found 

 south of Britain. 



Tropiion truncatus, Strom. 



" On all parts of the Irish coast " — Thompson (sub Fusus Bamffias). Liv- 

 ing in from 6 to 25 fathoms around Belfast Lough, and in much deeper water 

 (70-90 fathoms) off the Maidens, and common in a dead state in from 12 to 

 100 fathoms — Hyndman. Very rare, dead, in Strangford Lough and the 

 channel adjoining — Dickie. (Both sub T. clathratus.) 



[Fusus scalariformis, recorded by Hyndman as found in Turbot Bank sand 

 by Mr. Jeffreys, is Tropiion clathratus, a characteristic fossil of all glacial and 

 post-glacial beds.] 



[Fusus decussatus of Brown (Illust. Conch. G. B.) is said to have been 

 discovered by him at Killough, Co. Down. The figures and description are 



* Since above went to press, the writer has dredged it alive in 3 fathoms off Rockport, 

 Belfast Lough.
