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 § Hartley. 



" This rare species has been taken in Donegal by Mr. Warren and Mr. 

 Barlee" — Forbes & Hanley (sub Skenea? rota). It is tbe smallest known 

 species of British shells, having a lengtb, according to Jeffreys, of only 0*0115 

 inch, and is rare. 



Caecum trachea, Montagu. 



Turbot Bank ; from Hyndman's collection— Belf. Mus. Coll. " Strangford 

 (Waller) " — Jeffreys (supplement). 



Caecum glabrum, Montagu. 



" Shell -sand, deep water, Belfast Bay, Mr. Hyndman"— Thompson (sub 

 Brochus Icevis). 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 Jeffreys says is common and universal ; its 

 insignificant size may account for this. 



[Brochus ret iculatus of Brown is the young of his B. annulatus, which is 

 an exotic shell. It is said to have been found in Strangford Lough.]. 



Turrltella terebra, Lhme. 



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 sheik? of this species constitute a large 

 part of the great shell-banks for which the place has long been noted. 



[Truncatella truncatula, Drapamaud. 



"A specimen agreeing with Montagu's description of Turbo subtruncata, 

 but not very well with his figure, was found among shell -sand collected at 

 Bundoran by Mrs. Hancock" — Thompson (sicb 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 Turtonae, 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 Belfast, 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,
