of the North of Ireland ’ 
Hanley [Skenea nitidissima) . Belfast Lough — Belf. Mus. Coll. Has probably 
been passed over on account of its very minute size ; it would seem to be a 
common species generally. 
Homalog-yra rota, Forbes $ Hanley. 
Tbis rare species has been taken in Donegal by Mr. Warren and Mr. 
Barlee Forbes & Hanley ( sub Skenea ? rota). It is the smallest known 
species of British shells, having a length, according to Jeffreys, of only 0*0115 
inch, and is rare. 
Caecum trachea, Montagu. 
TurDot Bank ; from Hyndman’ s collection — Belf. Mus. Coll. “ Strangford 
(Waller) ” — Jeffreys (supplement). 
Caecum g-labrum, Montagu. 
“ Shell- sand, deep water, Belfast Bay, Mr. Hyndman ’’—Thompson {sub 
Brochus lavis). Bare, in shell-sand from the Turbot Bank— Hyndman. 
These refer to the same station, and are the only notes of the occurrence in 
our district of the species, which J effreys says is common and universal ; its 
insignificant size may account for this. 
[Brochus reticulatus of Brown is the young of his B. annulatus , which is 
an exotic shell. It is said to have been found in Strangford Lough.]. 
Turritella terebra, Linne. 
Very common, living in 7 to 25 fathoms throughout our waters. Thompson 
says Mr. Hyndman observed it living between tide-marks in Carlingford 
Lough. In Lough Foyle the dead shells of this species constitute a large 
part of the great shell-banks for which the place ha^long been noted. 
[Truucafella truncatula, Braparnaud. 
11 A specimen agreeing with Montagu’s description of Turbo sub tr uncat a, 
but not very well with his figure, was found among shell -sand collected at 
Bundoran by Mrs. Hancock”— Thompson {sub T. Montagui). “ I fear 
there has been some mistake as to the specimen from this place ’’—Jeffreys. 
Its British distribution only extends to the south coast of England and 
the Channel Islands, and its foreign range is entirely southern.] 
Scalaria Turtouse, Turton. 
“At Newcastle, Co. Down, this shell has been met with by Dr. Drum- 
mond ’ ’ —Thompson. This station is given also by Forbes and Hanley, and 
Jeffreys, on Thompson’s authority. Strangford Lough— Mr. S. A. Stewart. 
As a pleistocene fossil it is of common occurrence in the Estuarine Clays at 
Belfast; perhaps the specimens labelled “Belfast Lough” in the Museum 
Collection were thus derived. 
Scalaria communis, Lamarck. 
“Although not yet (so far as I am informed) taken in the Loughs of 
Strangford or Beliast, it has been procured in the adjacent Lough of Larne ; 
Bundoran, Mrs. Hancock ’’—Thompson ( sub S. clathrus). Turbot Bank, 
dead, rare —Hyndman. Magilligan — Belf. Mus, Coll,
