LAMELLIBRANCHIATA. 
■347 
Two examples of this species were dredged from a depth of about 6 
fathoms in Strangford Lough, near Portaferry, in August, 1837, by Mr. 
Hyndman and myself ; and two more were in like manner procured by 
us in July, 1840, when, with Prof. Edward Forbes and Dr. R. Ball, dredg- 
ing in Killery Bay on the western coast — depth from 3 to 12 fathoms. 
Mr. Barlee includes it in his list of Birterbuy Bay shells dredged in 
1845, and Mr. M ‘Andrew in his list of species taken in or near Bantry 
Bay, in 1846. 
April 21, 1848. A valve of it, and one of A. Boysii , found in a large plaice 
caught in Belfast Bay by E. Getty, Esq. The stomach and intestines 
were almost filled with Solen pellucidus. 
There were also a Corbula striata and a Venus laminosa. 
Genus Cyprina. 
C. Islandica, Linn. 
Dublin Bay and Bray, Br. Turt. Commonly found on extensive 
sandy beaches, as Magilligan, Portmarnock, &c. Dredged in Belfast and 
Strangford Loughs, on sand and mud from about 5 to 12 fathoms, living ; 
dead shells obtained from the greatest depths there — about 25 fathoms, 
Mr. Hyndman and W. T. Dredged in Dublin Bay (Dr. Ball and W. T.), 
and in or near Bantry Bay, by Mr. M‘Andrew. Not included in the lists 
of species from the western coasts, nor was it obtained by our party in 
1840, by occasional dredging or otherwise, from Bundoran to the South 
Isles of Arran. 
C. minima , Mont. 
Miltown Malbay, rare, Professor Harvey ; Youghal, very rare, Miss 
M. Ball ; Bantry Bay, Mr. Humphreys, Mr. Barlee, and Mr. M‘ Andrew ; 
Birterbuy Bay, Dr. Farran, Mr. Barlee. I have seen a specimen from 
Erris, Co. Mayo (Miss Bingham), in the collection of Mr. Warren. 
“ Portmarnock, very rare,” Turt. Belfast Bay, Mr. Hyndman. 
Genus Mactra. 
M. solida, Penn. Dublin Bay, Br. Turt. 
Although found on each side of the island, not generally distributed : 
it is chiefly met with thrown ashore on extensive sandy beaches. Magil- 
ligan and Portmarnock are the chief localities in which it has occurred 
to myself ; in both of them Sertularia argentea is often found parasitic 
on it. 
Red Bay and Larne, Co. Antrim, W. T. Ballysodare, Co. Sligo (a 
monstrous var.), Mrs. Hancock. This is the only western habitat, in the 
MS. catalogues consulted. 
M. elliptica , Br. Portmarnock, W. T. 
Belfast and Strangford Loughs ; dredged in the former from 20 fathoms, 
shelly sand : specimens dead in both localities. 
M. truncata , Mont. 
Dublin coast, not uncommon, Br. Turt. Found, near low-water mark 
in sand; brought to Belfast with cockles for sale, and together with 
Venus aurea , similarly obtained, commonly called lady cockle. Red Bay, 
W. T. Ballysodare ; the remark in reference to this locality under M . 
solida equally applies to the present species.
