of the North of Ireland.

Fholas Candida, Linne. 
The most common of the genus in Belfast Lough, inhabiting the same 
situations as the last- Dickie dredged dead valves in 7-20 fathoms in Castle 
"Ward Bay, Strangford Lough. 
Pholas parva, Tennant. 
“ Was procured some years ago off the Long Strand, Belfast Bay, by Dr. 
J. L. Drummond ; subsequently by the Ordnance collectors at Whitehouse 
Point, in the same bay” — Thompson. Hyndman supplies the additional in'* 
formation that it was in submerged peat that it occurred in the former 
locality. 
Fholas crispata, Linne. 
“ Belfast Lough, Brown. Inhabiting indurated clay about low water mark, 
Belfast Bay” — Thompson. “Living in submerged peat at extreme low- 
water in Bangor Harbour, County Down, and in other places — Hyndman. 
Castle Chichester, in Triassic marl, but of very small size — Mr. Swanston. 
It flourishes on the shore at Cultra, near low water mark, in Boulder Clay, 
Hew Red Sandstone, and Carboniferous Shale ; at this place, from a piece of 
soft sandstone less than 6 inches square, the writer has taken P. dactylus , P. 
Candida , P. crispata , and Tapes pullastra var. perforans, all living. 
Pholadidea papyracea, Turton. 
“ Two specimens in the Ordnance Museum are labelled “ Portrush”, North 
of Ireland ” — Thompson ( sub Pholas papyracea ). “ Discovered in the dredg- 
ings of 1857, embedded in rolled lumps of hard clay, and again in the deep 
water this season ’ ’ (1858)— Hyndman. Off the Maiden Rocks, 70-90 fathoms, 
is the station where these specimens, which were living, were obtained. In his 
1859 Report, Hyndman again records it “living at the depth of 80 fathoms 
north of the Maidens, in small pieces of soft sandstone. The smaller speci- 
mens want the cup-shaped appendage, whether the effect of insufficient space 
or immature growth.” Hyndman first recorded it as Pholas striata , but sub- 
sequently corrected it to the present species. “Sandstone at low-water, 
Castle Chichester near Belfast (Hyndman)”— Jeffreys ; whence it has been 
obtained subsequently. Low water mark being its usual habitat, it is probable 
that all the deep water specimens above should go under the following variety, 
which is essentially a deep water form. 
var. aborta. “In soft sandstone dredged in 80 f. off the coast of Antrim 
(J.G.J.)”— Jeffreys. 
[Teredo Worvegica, Spengler. 
“ Donaghadee (Co. Down), the animal alive ” —Thompson. “Not known 
as living in the Bay ” — Hyndman. Probably stray specimens only have been 
met with here.]
