Odostomia truneatula, Jeffreys. 
A single specimen found among Turbot Bank sand by Mr. Jeffreys ; and 
later it was dredged in 25 fatboms off Black Head — Hyndman ; specimens 
from tbence are in the Belfast Museum. It is a very rare species, and its 
other British stations are all on the South of England coasts. 
Odostomia Ssiikisi, Jeffreys. 
“Bundoran, Co. Donegal, in drift shell sand (Waller) ” — Jeffreys. 
Odostomia rissoides, Hanley. 
Found by Jeffreys in Turbot Bank sand— Hyndman. Bundoran— Belf. 
Mus. Coll. It is a littoral species, and is distributed throughout the British 
coasts. 
var. alba. Turbot Bank, Mr. Waller— Hyndman ( sub 0. alba). 
var. nitida. Found by Jeffreys in Turbot Bank sand— Hyndman ( sub 0. 
nitida). 
var. diabia. As last (sub 0. dubia). 
Odostomia pallida, Montagu. 
“ A very few individuals of this species have been dredged in Belfast Bay, 
and taken in the stomach of the grey mullet captured there ; under stones 
between tide marks. Strangford Lough, on soft sand and ooze” — Thomp- 
son. Dredged in the vicinity of the Turbot Bank on several occasions — 
Hyndman ( sub 0. eulimoides). In shell sand dredged near Ardmillan in 
Strangford Lough— R.L1.P. It is one of the commoner Odostornice, and lives 
on the ears of Pecten opercularis and P. maximus, in the coralline zone ; the 
littoral habitat assigned above by Thompson for the species, casts some doubt 
on the correctness of his determination. 
Odostomia acuta, Jeffreys. 
From the Turbot Bank ; determined by Mr. Alder — Hyndman. 
Odostomia eonspieua, Alder. 
As last ; like it, it is an inhabitant of the coralline zone (15-50 fathoms). 
Odostomia uuidentata, Montagu. 
“ More frequent in the shell sand that has come under my notice than any 
other species of Odostomia'''’ — Thompson; he mentions Strangford Lough as 
a locality. Hyndman took it several times on the Turbot Bank, and Dickie 
off the entrance to Strangford Lough. Twin Islands in Belfast Harbour — 
Mr. Swanston. 
Odostomia turrit a, Hanley. 
Turbot Bank, Mr. Waller— Hyndman [sub 0. unidentata var. turrita). 
Odostomia plicata, Montagu. 
“It has been found in Belfast Bay and Strangford Lough by Mr. Hyndman 
and myself; at Bundoran by Mrs. Hancock” — Thompson. Bare, off 
Bangor, and on the Turbot Bank— Hyndman. Jeffreys gives no northern 
stations for the present species, and says that 0. .turrita has been often 
mistaken for it.
