 April 3, 1848. — A few fine specimens reaching to 7 inches in length,

Genus GoRGONiA. 

 G. anceps, Pall. 

 Stated by Ellis as found on Irish coast. 



G. verrucosa, Linn., Johnst. Brit. Zooph. 

 The first Gorgonia of any species which I have seen from the coast of 

 Ireland, was a portion of G. verrticosa sent to me by Dr. Ball. The 

 specimen was procured at the island of Lambay, oft' the Dublin coast, and 

 taken to Mr. Warren by the man who found it, on account of-the size (18 

 inches from base to extremity of branches), he having never seen any so 

 large before.J West of Ireland, R. Ball. 



Genus Alcyonium. 

 A. digitatum, Linn. 



Common on the coasts of Down and Antrim. 



Unattractive as this species is when dead, it is a highly beautiful object

X This has been inadvertently called Gorgonia fiaheUum in the published list 

 of donations to the Dublin University Museum, Dec, 1848, p. 8. A specimen 

 of G. flahelltmi, with the root attached, was brought up in a trawl-net from 8 to 

 10 fathoms depth oft' Bangor, Belfast Bay, last summer, by Mr. Hyndman, who 

 judiciously considered it a foreign specimen. That it had for some time been 

 a denizen of our seas was, however, evident from the native productions which 

 were attached, such as Crisia eburnea, Ccllularia ciliata, Grantia comprcssa 

 and G. ciliata, Serpula triqnetra, with small portions of Conferva and other 

 native Algae. This Gorgonia was 14 inches in height and the same in breadth.
