of the North of Ireland. 99 
on all kinds of ground and at all depths, from half-tide down to 100 fathoms, 
the limit of the British fauna. 
var. littoralis. Carrickfergus — Belf. Mus. Coll. It is probably common. 
var. striata. Living in 60 fathoms about 6 miles from the Maidens — Hynd- 
man. 
[Buccimim cyaneum, 
“ fragment only, considered by Mr. Jeffreys to he this species, in Turbot 
Bank sand, Mr. Waller” — Hyndman, 1858 Report. I have failed to trace 
this species to a modern synonym ; it is probably some glacial fossil.] 
IVXurex erinaceus, Linne. 
Of general occurrence ” — Thompson ( Triton erinaceus). Jeffreys, after 
giving a list of British stations, remarks “all the specimens procured from 
the northern coasts were dead and this remark applies to our province, for, 
though it is of frequent occurrence on the shore, and in depths up to 30 
fathoms, I find no note of its having been taken alive.* 
Troplion murieatus, Montagu. 
Hyndman dredged it alive on the Cod Bank off Larne (20 fathoms), and 
also in 25 fathoms off Black Head, hut very sparingly ; and took it rather 
commonly in a dead state off Donaghadee, and on the Turbot Bank, and in 
70-100 fathoms near the Maidens. From Dickie’s Report, dead shells appear 
to he distributed throughout Strangford Lough and the channel adjacent. 
J effreys queries these and other northern records, and considers that they are 
probably referable to T. Barvicensis. The present species has its head- 
quarters in Lusitanian and Mediterranean waters, and does not range north of 
Britain. 
Troplion Barvicensis, Johnston. 
Hyndman obtained it living with the last in the two stations mentioned, 
and dead in 8-10 fathoms in Belfast Lough, and on the Turbot Bank. 
Dickie dredged a few dead specimens in 12-15 fathoms outside Strangford 
Lough. This is a northern form, ranging to the arctic seas, and not found 
south of Britain. 
Troplion truncatus, Strom. 
“On all parts of the Irish coast ” — Thompson ( sub Fusus Bamffius). Liv- 
ing in from 6 to 25 fathoms around Belfast Lough, and in much deeper water 
(70-90 fathoms) off the Maidens, and common in a dead state in from 12 to 
100 fathoms — Hyndman. Very rare, dead, in Strangford Lough and the 
channel adjoining— Dickie. (Both sub T. clathratus.) 
[Fusus scalariformis, recorded by Hyndman as found in Turbot Bank sand 
by Mr. Jeffreys, is Troplion clathratus , a characteristic fossil of all glacial and 
post-glacial beds.] 
[Fusus decussatus of Brown (Illust. Conch. G. B.) is said to have been 
discovered by him at Killough, Co. Down. The figures and description are 
* Since above went to press, the writer has dredged it alive in 3 fathoms off Roekport 
Belfast Lough.
