not sufficient for identification. Jeffreys suggests that it may fiave been a 
plain-coloured variety of Trophon Syracusanus, which is a rather common 
Mediterranean shell.] 
Fusus antiquus, Linne. 
Living commonly around the coast, ranging in depth from between tide- 
marks in Belfast Lough to 100 fathoms at the Maiden Bocks. Called 
“ buckie ” along with Buccinum undatum. 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. Samue 
Yance. 
var. alba. Carrickfergus— Belf. Mus. Coll. 
Fusus gracilis, J)a Costa. 
Frequent, but not so generally distributed as the last. Hyndman (hedged 
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. 
Iffassa 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-E.Ll.P. Not recorded from Strang- 
ford Lough. I have dead shells from Portrush and Magilligan. 
18-assa incrassata, Strom. 
Abundant throughout the province, living m from 7 to 90 fathoms. A. 
macula of Thompson’s work. 
Tffassa pygmeea, Laniard. ■ . 
Yery rare In Hyndman’s 1858 Eeport it is noted as having been taken 
alive by Mr. Waller on the Turbot Bank ; in the previous Eeport 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 X. mcmsmia 
is unknown. 
rX3"assa hepatica, Montagu. 
Becordecl from Strangford Lough, on the authority of Turton and Brown 
( Monoceros hepaticus). It is a West Indian shell.] 
tC0 A“ratHn* 0 ytdman’s Beports for 1857 and 1858 {sub Mangelia Eolbolii 
and Buccinum Eolbolii) as dredged on the Turbot Bank. It is an inhabitan 
of the arctic seas, and occurs in Britain only as a glacial fossil.]
