130 LIVERPOOL MARINE BIOLOGY COMMITTEE REPORT. 



Family. — Zoanthid^. 

 Sub-family. — ZoANTHiNiE . 

 Polythoa arenacea, Delle Chiaje (1886). 



Zoanthus coucJiii, Johnston (1838). 

 Several examples of this species, which is not recorded 

 by Gosse from any locality nearer to us than the Irish coast, 

 were obtained by Professor Herdman, along with Corynactis 

 viridis, off Spanish Head, at the south end of the Isle of 

 Man, from a depth of twenty fathoms. This is therefore a 

 new locality for both these species. The specimens are 

 adherent to fragments of a Nullipore. 



Family. — Cerianthid^ . 

 Sub-family. — Cerianthin^e . 



Ceriauthus lloydii, Gosse (1859). 



So named by Mr. Gosse from its discoverer, Mr. Alfred 

 Lloyd, who found it in the Menai Straits, in July, 1856. 

 This species also deserves to be specially looked for in future 

 expeditions. 



Of the twenty species of Actiniaria recorded by Gosse as 

 inhabiting the Irish Sea (for one of which, however, Sagartia 

 nivea, he gives no Irish Sea locality), seventeen are known 

 to inhabit the Liverpool Bay district, and of these eleven 

 have been collected by members of the Committee. 



Only four distinct species {Actinia equina, Cylista 

 undata, Tealia crassicofiiis, and Actinoloha dianthus) are 

 recorded in Byerley's list. They were all obtained in the 

 immediate neighbourhood of Liverpool.
