Cyathina Smithii. 



This would appear to occur as a rare species all round the coast. It 

 has been taken alive in Belfast Bay ; in Dublin it occurs off Lambay and 

 Dalkey Sound. According to a note in Thompson, it has been taken 

 in some numbers on the Nymph Bank of Waterford. This I regard as 

 rather a strange locality, never having dredged them in deep water ; 

 and my own experience and that of Mr. Gosse (see "Devonshire Coast") 

 would go to prove that it occurs at or near low- water rock, adhering to 

 the perpendicular -Bides of rocks. Youghal : Miss Ball. — I have found 

 it common in Bantry Bay, and Dr. Ball has taken it at Bundoran, a fa- 

 vourite watering-place in Donegal. I am rather inclined to think that 

 the paucity of our Madrepores may be accounted for by their being all 

 regarded as belonging to this species. 



The annexed Table, though of course imperfect, will serve to show 

 for the present the distribution of the previously mentioned species : —
