of the North of Ireland. 79 



Pholas 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, Pennant. 



" 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. 



Pholas 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, 

 New 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, Tarton. 



" Two specimens in the Ordnance Museum are labelled " Portrush", North 

 of Ireland " — Thompson (sub Pholas papyracea). " Discovered in thedredg- 

 ings of 1857, embedded in rolled lumps of hard clay, and again in the deep 

 waterthis season" (1858)— Hyndman. Off the Maiden Eocks, 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.]
