Echinus esculentus, Linn. 



This common species, the Echinus sphcera of Forbes' 

 British Star Fishes, and other works, is common off the 

 south end of the Isle of Man. It was taken frequently last 

 summer in the neighbourhood of Port Erin, and some 

 very large specimens occurred. In one case the Annelid 

 Hermadion assimile was found coiled around the edge of 

 the peristome of the Echinus. 



One or two specimens have been found, cast ashore near 

 Liverpool, by Mr. Marrat (Byerley) ; and it was obtained at 

 low tide at Hilbre Island, on June 13th, 1885. 



Forbes {Brit. Assoc. Rep.) records this species from the 

 Isle of Man, but not from the shores of North Wales. It was 

 obtained during the cruise of the " Hyaena," between Puffin 

 Island and Anglesea, on May 25th, 1885, and was taken by 

 Mr. Thompson in the neighbourhood of Penmaenmawr. 



Echinus miliariSf 0. F. Miiller. 

 This species is recorded by Mr. Byerley as having been

 by Prof. Forbes from the Isle of Man, and from the coast of 

 North Wales.
