pure sand in each case— Thompson. Hyndman records dead shells only, 

 which appear to be of frequent occurrence in the neighbourhood of the 

 Turbot Bank. Dickie dredged a few living examples off the entrance to 

 Strangford Lough, in 12-15 fathoms, and dead specimens inside the lough. 

 Off Bangor, in 8 fathoms, living— Mr. Swauston. 



Bulima distorta, Beshayes. 



Bundoran, Mrs. Hancock— Thompson. Dead shells are not unfrequent on 

 the Turbot Bank, according to Hyndman. 



var. gracilis. Dredged by Hyndman on the Turbot Bank, and by Dickie in 

 12-15 fathoms outside Strangford Lough. 



[Eulima subulata, Donovan. 



Stated by Thompson to have been obtained at Bundoran, Co. Donegal, and 

 Dundrum, Co. Down, but there is no doubt that E. bilineata is the species 

 intended.] 



Bulima bilineata, Alder. 



" Dredged from a sandy bottom, 8-10 fathoms, off Dundrum, Co. Down, 

 Mr. Hyndman and W.T. ; a specimen at Bundoran, Mr. "Warren " — Thomp- 

 son (sub E. subulata). Dead shells are common on the Turbot Bank— Hynd- 

 man. Living, very rare, in 7-20 fathoms, in Strangford Lough, and dead in 

 the channel adjoining— Dickie. * 



Matica Xslandica, Gmelin. 



Dead; a single young specimen by Mr. Jeffreys" — Hyndman, 1859 

 Report {sub JV. helicoides). The locality is not given, but was probably the 

 Turbot Bank. This specimen may have been a quaternary fossil. It is a 

 northern species, which in Britain is taken chiefly on the northeast coasts, 

 though it has been found at Cork. It is widely distributed in post-glacial 

 beds. 



[OT. Groenlandica, Beck. 



A shell from the Turbot Bank is in Thompson's collection in the Belfast 

 Museum. Any specimens occurring there are not recent, but relics of the 

 glacial epoch ; Jeffreys records it also as dredged on the Turbot Bank, and 

 enters it as a fossil. Its present habitat in Britain is limited to rather deep 

 water off the northeast coasts of England and Scotland.] 



TFatica sordida, Bhilippi. 



Strangford Lough and the channel adjoining are the only localities in 

 which this species has been obtained in the North of Ireland. Here Dickie 

 dredged it on several occasions, but only in a dead state, in depths varying 

 from 10 to 25 fathoms; specimens from the same locality are in Thompson's 

 collection in the Belfast Museum. 



TTatica catena, Ba Costa. 



One of our commoner shells, living chiefly in sandy bays at a few fathoms 

 depth. " Living, common, 6-8 fathoms, from Bangor to Donnghadee" — Mr. 

 S. A. Stewart. Thrown up alive, and of large size, on Magilligan Strand,
