The papers of the late "William M'Calla on the star -fishes of the west 

 coast, and of Belfast Bay; and Professor J. Beay Greene's paper onAm- 

 phmra Zeachu, a new species of Ophinridea discovered at Cork. 



The following list shows in detail the species added to the Irish lists 

 since the publication of Forbes; but probably one or two of the species 

 are of questionable value. 



Ophiura Zeachu (Greene). Cork, 1858. Professor J. Beay Greene. 

 Brissus lyrifer {Forbes). South-west coast. Mr. B. M 'Andrew. 

 Cucumaria niger {Couch). West coast. Mr. W. Todhunter. 

 Cucumaria inhcerens {Mull). Balbriggan, county of Dublin, 1843. 



Mrs. W. J. Todhunter. 

 Thy one Andrewsii {Farran). Clonea, county of Waterford, Dr. C. 



Parran. 

 Thyone raphanus {Kor. 8f Dub.). Bantry Bay. Mr. B. M'Andrew. 

 Chirodota digitata {Mont.). Carrickfergus. Mr. W. Thompson. 

 Syrinx Harveii {Forbes). Strangford Lough. Mr, G. C. Hyndman. 

 Syrinx tenuicinctus {M'Coy). West coast. Professor M'Coy. 



,, Forhesii {M^Coy). Boundstone. Professor M'Coy. 

 Echiurus vulgaris {Savign.). Clonea. Dr. C. Parran. 



All of these, except the first and Thyone Andrewsii, are recorded in 

 Thompson's Pauna of Ireland. A specimen of Echinus presented to this 

 Society by Mr. G. Y. Du JS^oyer, and noticed in the Proceedings for 

 1856, almost seems to point to a species as yet undistinguished from 

 Echinus lividus. 



The great addition made to our knowledge among this group is to 

 be judged rather by the positive knowledge gained as to the actual range 

 of the several species, than by the mere number of species added to our 

 lists ; and the general conclusion thence anived at, that most of the spe- 

 cies recorded as of limited distribution are really distributed all round 

 the island. 



In the Irish seas the Echinodermata probably afford us fewer ex- 

 amples of types of geographic importance than any other group, — one 

 exception is Echinus lividus , whose range at present stands thus : — 

 Lough Ine, county of Cork, on the authority of fine specimens sent thence 

 by Mrs. Thomas Townsend, as its furthest south-eastern point, to Tory 

 Island, county of Donegal, on authority of Mr. G. C. Hyndman. There 

 are not probably a dozen other species of restricted distribution. The 

 following, however, will probably be found to be so : — Crihella rosea., 

 Goniaster Templetoni, Luidia fragillissima, Asterina gibbosa, Echinus 

 Flemingii, Brissus lyrifer, Cucumaria niger, Cucumaria fusiformis, and 

 possibly also Ophiocoma brachiata, Solaster endeca, Palmipes membrana- 

 ceus, Psolus phuntapus, and Cucuma/ria pentactes. Of these, Asterina 

 gibbosa is given by William Thompson on his own authority, as having 

 occurred off the Dublin coast. I have often searched for it carefully, 

 and dredged over grounds similar to those in which it has occurred to 

 me off Plymouth, but unsuccessfully on the Dublin coast ; whilst on the
