Iiassea rubra, Montagu. 
Common between tide marks— Hyndman. Portrusb, and Belfast Bay — 
Thompson. (Both sub Kellia rubra). Magilligan— Belf. Mus. Coll. 
Kellia 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. 
Eecorded from the Turbot Bank, dead, by Hyndman, 1857 Deport ( sub 
Lucina leueoma). 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 spinifera, Montagu. 
“At Ded Bay, County Antrim, I found a valve of this species”— Thomp- 
son. Hyndman dredged it once alive “ on a bank called ‘ The Diggs,’ 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. 
Xiucina borealis, Linne. 
Commonly dredged in a dead state, in Belfast and Larne Loughs and the 
deeper waters adjacent, in all depths from 1 to 30 fathoms. Thompson men- 
tions it {sub L. radula) as found at Ded 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 Mollmca 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 foimd 
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). 
Cyamium 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,
