Mr. Thompson's Additions to the Fauna of Ireland. 245 



XXVIII. — Additions to the Fauna of Ireland. By W. Thomp- 

 son, Esq., Vice-Pres. Nat. Hist. Society of Belfast. 



[Continued from p. 14.] 



Mollusca*. 



Scalaria Trevelyana, Leach. MS. Several years ago I was favoured 

 with specimens of this handsome shell from the coast of the 

 county of Cork by Mr. John Humphreys. Like many other 

 British mollusca long known to naturalists it still remains un- 

 described, but it is not for me to attempt its description. I 

 learn from Mr. Alder that it was discovered many years ago on 

 the coast of Northumberland by Miss Emma Trevelyan, in 

 honour of whom it is named. 



EcHINODERMATA. 



Asterias aurantiaca, Linn. Youghal, Mr. R. Ball ; coasts of Down 

 and Antrim, W. T. ; Ross bay and south-west coast of Cork, 

 common, Mr. G. J. Allman. 



\Asterina gibbosa, Forb. Wern. Mem. vol. viii. part 1. 



Asterias gibbosa, Penn. Coasts of Down, Antrim, and Dublin, 

 W. T. ; Southern and western shores, Mr. R. Ball. 



Linkia rosea, mihi. 



Asterias rosea, Mull. Zool. Dan. vol. ii. p. 35. tab. 67. In Mr. R. 

 Ball's collection, I have seen two specimens of this star-fish, 

 which is an addition to the British Fauna — they were obtained 



* Trochus millegranus, Philippi, Enum. Moll. Sicilise, p. 183. tab. lO.f. 25. 

 This species has been in my collection for some years from the northern and 

 southern localities of Strangford lough and Bantry bay. Mr. Forbes informs 

 me that it is to this Trochus the name of T. Martini is applied in Mr. Smith's 

 paper lately published in the Wernerian Memoirs (vol. viii. Part I.). It is 

 there stated that Mr. Alder found the species at Duhlin ; but I understand 

 that the Irish specimens thus alluded to were not from that locality, but 

 from the one first mentioned here. Mr. Humphreys of Cork, from whom 

 I had the Bantry bay specimen in 1835, stated that Dr. Turton had named 

 it T. conuloides. 



f Goniaster Templetoiii, Thomp. Forbes, Wern. Mem. vol. viii. On ex- 

 amination of a species of Goniaster obtained by Mr. Ball from the Nymph 

 Bank more than twenty years ago, it seemed to correspond with the descrip- 

 tion of what Mr. Templeton considered doubtfully as the Ast. equestris 

 (Mag. Nat. Hist. vol. ix. p. 237.) and appearing at the same time to be un- 

 described I named it as above. Mr. Templeton's specimen is not now 

 available for comparison, but the gentleman who found it, on being lately 

 shown one from the south, stated that they were certainly of the same spe- 

 cies. The G. Templetoni approaches the Ast. pulvillus, Mull. Z. D. vol. i. 

 p. 19. tab. 19. more nearly than any other, and chiefly differs from it in the 

 under surface being conspicuously tessellated.
