Dead specimens dredged near South Isles of Arran, Mr. Barlee. 
Genus Ervilia. 
E. castanea, Mont. 
Procured with the valves united on the coast of Galway, by Mr. Barlee, 
in 1848. All previous specimens obtained on the British coast (off Corn- 
wall and the Scilly Islands) were but single valves, according to the work 
particularly referred to for this species. 
Genus TellinA. 
T.fctbula, Don. 
Dublin coast, Br. Turt. Not uncommon on extensive sandy beaches, 
as Portmarnock and Magilligan, W. T. Found from below low-water mark 
to a few fathoms, on sand. 
Specimens found in the stomachs of plaice ( Platessa vulgaris), caught on 
the Dublin coast, have been given to me by Dr. Farran. Ardmore, Mrs. 
Mackesy. 
T. tenuis , Don. 
Dublin coast, Br. Turt. A common gregarious species found commonly 
about low- water mark in sand, and like T.fabula to a few fathoms’ depth. 
The plaice in Belfast Bay feed very much on T. tenuis. 
Dundalk Bay, Mr. Hyndman. Dredged in Clifden Bay, 1840. On 
some parts of the Galway coast, said by Dr. Farran to be eaten by the 
people. 
T. squalida , Pultn. 
Dublin coast, Br. Turt. Found sparingly on sandy coasts. 
Red Bay, Co. Antrim, Mrs. J. Thomson Tennant, and Dundalk, Mr. 
Hyndman, may be named as additional localities. 
T. Donacina, Linn. 
Bantry Bay, Dublin coast (one valve), and Bray (Mr. M. J. O’Kelly), 
were noticed by Brown and Turton as localities for this species. The 
first-named locality is its chief one known to me in Ireland ; at Portmar- 
nock it is but occasionally found. Specimens have but rarely been 
dredged by us in Strangford Lough (Mr. Hyndman and W. T). And I 
once met with it in the stomach of a haddock, taken on the open coast of 
Down. Birterbuy Bay, Dr. Farran, Mr. Barlee. From Co. Clare, in 
Mr. Warren’s collection.
