Among oysters from Killinchy (Temp. MSS.), in the stomach of a haddock 

 taken at Newcastle, Co. Down, and in other localities on the North-East 

 coast — Thompson {sub C. fuscatus, Brown). Though it is a common species 

 generally, neither Hyndman nor Dickie has any note of it. Belfast Lough — 

 Belf. Mus. Coll. 



Chiton ruber {Linne), Lowe.

OEDEE PECTINIBEANCHIATA. 



Patella vulgata, Linne. 



Between tide marks, on stones and rocks ; very common here, as elsewhere. 

 Hyndman dredged dead shells in 27 fathoms on the Turbot Bank. He makes 

 a curious statement about the limpet on the authority of Captain White, 

 Harbour Master — that it is found to be good for eating and wholesome on the 

 outer coast of Co. Down, but that in Strangford Lough it is found not to be 

 wholesome, and is avoided by the people there. There is an interesting 

 paper in the " Annals of Natural History" for June, 1839, by the late Mr. 

 Robert Patterson, F.R.S., on the use of tbe limpet as food in the North of 

 Ireland, which will well repay perusal.
