Iiassea rubra, Montagu. 



Common between tide marks— Hyndman. Portrush, and Belfast Bay — 

 Thompson. (Both sub Eellia rubra). Magilligan— Belf . Mus. Coll. 

 XCellla suborbicularis, Montagu. 



Bundoran— Thompson. Dead, rare, in 10 fathoms in Belfast Bay, and on 

 the Turbot Bank - Hyndman. In Strangford Lough, and in the Irish 

 Channel adjoining, Dickie found it living in 7 to 25 fathoms. Magilligan— 

 Belf. Mus. Coll. 

 Xioripes lacteus, Linne. 



Recorded from the Turbot Bank, dead, by Hyndman, 1857 Report (sub 

 Lucina leucoma). This record is not confirmed by Jeffreys, and as the species 

 was not obtained again, and is entirely a southern form, it is doubtful if it 

 should be included in our fauna. 

 Xiucina splnifera, Montagu. 



"At Red Bay, County Antrim, I found a valve of this species"— Thomp- 

 son. Hyndman dredged it once alive " on a bank called ' The Riggs,' lying 

 south of the Copelands, about a mile south of Donaghadee, and a mile from 

 shore, in about 20 fathoms," and several times dead, off Belfast Lough, in 

 15-30 fathoms. 

 Iiucina borealls, Linne. 



Commonly dredged in a dead state, in Belfast and Lame Loughs and the 

 deeper waters adjacent, in all depths from 1 to 30 fathoms. Thompson men- 

 tions it (sub L. radula) as found at Red Bay, and in 6 to 12 fathoms in Belfast 

 and Strangford Loughs, by himself and Mr. Hyndman, but as the latter 

 naturalist, in his subsequent report on the Mollusca of Belfast Bay (1857), 

 notes it only in the column of dead shells, it may be assumed that such alone 

 were found in the locality named. In Strangford Lough Dickie took it 

 frequently alive, in depths ranging from 7 to 25 fathoms. Single valves are 

 commonly thrown ashore on the Derry coast, where also the writer has found 

 living specimens. 

 Axinus flexuosus, Montagu. 



" Widely distributed, but in sparing numbers " — Thompson. I find no note 

 of its having been taken alive. Hyndman dredged dead specimens occasionally 

 in 5-30 fathoms, and Dickie, in Strangford Lough, 4-25 fathoms. Thompson 

 gives Strangford Lough and Bundoran as localities. (Mentioned by the authors 

 quoted sub Lucina Jlexuosa) . 

 Cyamlum minutum, Fabricius. 



Abundant, among sea-weeds and stones near low-water mark. Thomp- 

 son states (sub Montacuta purpurea) that the shoals of mullet (Mugil chelo) 

 consume vast quantities of them when roving over the Zostera banks 

 in spring and summer, and Hyndman (sub Turtonia minuta) estimates that in 

 the stomach of a mullet taken in Larne Lough, there were 35,000 of these 

 little shells.
