not sufficient for identification. Jeffreys suggests that it may have heen a 

 plain- coloured variety of Trophon Syracusanus, which is a rather common 

 Mediterranean shell.] 

 Fusus antiquus, Unite. 



Living commonly around the coast, ranging in depth from hetween tide- 

 marks in Belfast Lough to 100 fathoms at the Maiden Bocks. Called 

 " buckie " along with Buccinum andatum. Specimens of great size from Car- 

 rickfergus are in the Belfast Museum Collection. A curious convoluted mon- 

 strosity is mentioned by Hyndman as dredged off Groomsport by Mr. Samuel 

 Vance. 

 tar. alba. Carrickfergus— Belf. Mus. Coll. 

 Fusus gracilis, Da Costa. 



Frequent, but not so generally distributed as the last. Hyndman dredged 

 it alive in 60 to 90 fathoms off the Maidens (F. Islandicus). Jeffreys gives 

 its range as 20 to 145 fathoms, but it frequents less depths in our district, as 

 it has been dredged living in abundance in 6-8 fathoms off Bangor by Mr. S. 

 A. Stewart, and is sometimes thrown ashore in quantity, with the animal 

 quite fresh, between Holywood and Craigavad, where the greatest depth of 

 water in the vicinity does not exceed 4 or 5 fathoms, and the writer has 

 noticed it living between tide-marks at Cultra. It did not occur to Dickie in 

 Strangford Lough, nor have I observed it on the Derry coast. It is F. 

 corneus of Thompson's work. 

 Tfassa reticulata, Linne. 



Would appear to be somewhat local. Occasionally found living about Bel- 

 fast Lough, in 10 to 20 fathoms; dead on the Turbot Bank — Hyndman. 

 Living between tide-marks at Cultra — R.L1.P. Not recorded from Strang- 

 ford Lough. I have dead shells from Portrush and Magilligan. 

 VTessa incrassata, Strom. 



Abundant throughout the province, living in from 7 to 90 fathoms. N. 

 macula of Thompson's work. 

 Tuassa pygmsea, Lamarck. 



Very rare. In Hyndman's 1858 Report it is noted as having been taken 

 alive by Mr. Waller on the Turbot Bank ; in the previous Report it had been 

 recorded with doubt from the same vicinity, by Dr. Dickie, but only in a 

 dead state. It is a common shell in our Estuarine Clays, where A r . incrassata 

 is unknown. 

 [Wassa bepatica, Montagu. 



Recorded from Strangford Lough, on the authority of Turton and Brown 

 {Monoceros hepaticus). It is a West Indian shell.] 

 [Columfcella Holbolii. 



Appears in Hyndman's Reports for 1857 and 1858 {sub Mangelia Holbolii 

 and Buccinum Holbolii) as dredged on the Turbot Bank. It is an inhabitant 

 of the arctic seas, and occurs in Britain only as a glacial fossil.]
