Bank— Hyndman {sub Chemnitzia rufescens). “ Lough Strangford (Dickie) ” 
— Jeffreys. 
Odostomia rufa, Philippi. 
var. fulvoclncta. Turbot Bank, rare ; determined by Mr. Alder — Hyndman 
{Chemnitzia fulvocincta). Bundoran— Belf. Mus. Coll. The Chemnitzia 
rufa of Hyndman’ s 1858 Report, in Jeffreys’ list of Turbot Bank shells, in 
all probability belongs to the variety ; the typical form is exclusively 
southern, while the variety has a northern distribution. 
Odostomia lactea, Linne. 
Not uncommon— Thompson. Dredged frequently around the Turbot Bank 
by Hyndman, and in Strangford Lough and the. open channel adjacent by 
Dickie (all sub Chemnitzia eleg antissima) . Twin Islands in Belfast Harbour— 
Mr. Swanston. Bundoran — Belf. Mus. Coll. It is a common but beautiful 
species, inhabiting the laminarian zone. 
Odostomia Scillee, Scacchi. 
Both Waller and Hyndman dredged this shell on the Turbot Bank ( Euli - 
mella Scillce). Jeffreys, referring to this station, says “ perhaps from a post- 
glacial deposit.” Specimens from the Turbot Bank are in the Belfast Museum, 
and look quite as recent as the majority of the shells from that vicinity. 
Odostomia acicula, Philippi. 
Found in Turbot Bank sand by Mr. Jeffreys — Hyndman (sub Eulimella 
acicula). The collection in the Belfast Museum contains specimens from that 
locality. 
var. ventrieosa. Turbot Bank, Mr. Waller — Hyndman {subPulimella affinis). 
var. olbeliscus. “ Dredged by Mr. Waller on the north-east coast of Ireland ” 
— Jeffreys. Possibly this and the previous note refer to the same specimens. 
Odostomia nitidissima, Montagu. 
11 Specimens from Bundoran have come under my inspection ” — Thompson 
{Chemnitzia nitidissima). 
Xanthina rotundata, Leach. 
This beautiful oceanic species, popularly known as the “blue snail,” is 
occasionally wafted to our shores by the western winds, during the autumn 
months. Thompson mentions having obtained a few shells, still containing 
the animal, on the beach at Groomsport in Co. Down, in the year 1836 {sub 
I. communis ), but it is very rarely that it is found so far south in the channel. 
On the north coast of Antrim, and on the coast of Derry, it is of more fre- 
quent occurrence, and is occasionally washed in in quantity. I am informed 
that after October gales the strand at Bush-foot is sometimes thickly strewn 
with it. Portrush, occasionally — Miss Richardson, and R.L1.P. 
Eulima polita, Linne.
