Scalaria Trevelyana, Leach. 
“Mr. Hyndman possesses a specimen from Magilligan Thompson, 
specimen from thence, out of Mr. Thompson’s collection, is in the Belfast 
Museum. It does not appear to have been taken elsewhere in the province. 
Scalaria clatbratula, Adams. 
“ Bundoran, Mrs. Hancock ’’-Thompson ; specimens from thence are in 
the Belfast Museum. Hyndman dredged dead shells on several occasions, in 
the vicinity of the Turbot Bank.

“Transactions of the Royal Dublin Society,” and provisionally named 
Turritella Sibernica ’’—Hyndman {sub Scalaria Eschnchti). “ Dredged m 
18-20 f. off the coast of Antrim, by Mr. Hyndman, Mr. Waller, and myself.

V ar. tenuicula. “Lough Strangford (Waller) ’’-Jeffreys. 
Genus Odostomia, Fleming. 
This, the largest and perhaps the most complicated genus of British shells, 
has by no means been worked out in our district. With the assistance of 
that eminent conchologist, Mr. Jeffreys, Hyndman was enabled to publish 
very full lists of the Odostomia of the Turbot Bank, and of the 34 British 
species, no less than 21 are recorded from this vicinity, all in a dead state ; 
but beyond this, there is a paucity of information concerning them. Then- 
minute shells are easily overlooked, and it is only with the aid of the micro- 
scope that the exquisite sculpture which characterises many of the species, 
may be seen with advantage. In the absence of records of any of the 
following species having been taken alive, I have omitted noting “dead 
after each station. 
Odostomia nivosa, Montagu.
