End of Jxli/, 1847. — Judging chiefly from its dark reddish-brown 

 (mahogany colour) hue, in which it is strikingly different from the latter, 

 is abundant at Holywood Warren, having taken the place of the next 

 species, which was plentiful in the middle of July. 



C. capillata, Linn. (sp.). 



North and West of Ireland. 



3Ii(l. Juhj, 1847. — What I take to be this species from its light colour, 

 &c., abundant of all sizes to near' 18 inches diameter at Holywood 

 Warren. 



The same stinging species at same place and of huge size (same as 

 thrown on the beach, nearly a yard in diameter, i. e. feelers, &c., and appear- 

 ing as one mass), I remarked the first about ten days ago. 



The two last named are the only native stinging species, according to 

 Prof. Edward Forbes. One of these species at least makes its appearance 

 in Belfast Bay in multitudes at the beginning of August.
