Co. Deny — E. LI. P. Dead shells were dredged in some abundance around 
Belfast and Strangford Loughs by ILyndman and Dickie, in from 15 to 30 
fathoms (JV. moniliferci) . 
OTatica Alders, Forbes. 
This very pretty shell is common, living at nearly all depths (4 to 90 
fathoms) throughout the waters dredged by ILyndman and Dickie (/V. nitida), 
and thrown up on sandy beaches throughout the province. 
OTatiea Montaeuti, Forbes. 
Thompson records a living specimen dredged in Belfast Bay. Hyndman 
took it alive off Larne, at different depths up to 90 fathoms, and dredged dead 
shells in abundance around the entrance to Belfast Lough, in 15 to SO 
fathoms ( sub N. Montagui). It did not occur in any of Dickie’s dredgings. 
[Katica clausa, Broderip $ Sowerby. 
Dredged by Hyndman and Jeffreys on the Turbot Bank. It is a glacial 
fossil, and now inhabits the circumpolar seas alone.J 
AdeorMs subearinatus, Montagu. 
Dredged up from the Turbot Bank by Hyndman, in a dead state, on several 
occasions ; it is a southern shell, and has not been found elsewhere in our 
district. 
Ziamellaria perspieua, Linne. 
“ Generally distributed ” — Thompson (Sigaretus perspicuus) . Bare, living- 
on Laminaria, and dredged alive in the unusual depth of 80 fathoms north of 
the Maidens, and dead in 15-25 fathoms off Ballygalley Head — Hyndman. 
Very rare, dead, in 15-25 fathoms off the entrance to Strangford Lough — 
Dickie. Sigaretus tentaculatus, recorded by Thompson as dredged by Mr. 
Hyndman and himself in Strangford Lough, is the male of the present 
species ; the typical form is the female. 
Velutina Isevig-ata, Fennant. 
A species of frequent occurrence, living on hard ground at all depths. 
Hyndman took it alive in 12 to 20 fathoms off Belfast Lough, and in 70-90 
fathoms near the Maidens ; and in a dead state on the Turbot Bank. Dead, 
rare, in 6 to 8 fathoms, off Bangor — Mr. S. A. Stewart. It did not occur in 
Dickie’s dredgings, probably owing to the muddy nature of the bottom in 
Strangford Lough. Thrown up by the tide at Newcastle, Portrush, and 
Magilligan — B . LI. P. 
var. Candida. Jeffreys found this white variety on the coast of Antrim. 
Tricbotropsis borealis, Broderip $ Sowerby. 
In Hyndman’s Beports for 1857 and 1858, this species is noted as occur- 
ring in a dead state in almost every haul of the dredge made around the 
entrance to Belfast Lough, and on the Turbot Bank especially ; in the 1859 
Beport he records having obtained it alive in the latter place. Dead shells 
also occurred to him in the deepest water at the Maidens. Dickie dredged a
