Mr. Thompson's Additions to the Fauna of Ireland. 249 



R. Patterson informs me that he obtained the G. hcemispharica 

 at Lame in the summer of 1835. 



Rhizostoma Cuvierii, Blainv. Actin. p. 297. t. 44. f. 1. Belfast, Au- 

 gust 6, 1838. I received a fine specimen of this Medusa from 

 Edmund Getty, Esq., whose attention was called to it yesterday 

 by an old fisherman seventy years of age, who stated that " a 

 large starfish, he had not seen the like of before," was lying 

 on the beach near Holy wood (Belfast bay) . The specimen ex- 

 actly accords with Blainville's figure of R. Cuvierii and with 

 the Med. undulata of Borlase, as quoted by Pennant and Fleming. 

 Its total length is 18 inches, the body 7\, and thence to extre- 

 mity of peduncles 10^ inches : entire outer surface of the body, 

 which is 12 inches in diameter, granulated over like the rind 

 of an orange or lemon. The body is almost hyaline, with a very 

 slight tinge of dusky yellow ; peduncles and their appendages 

 delicately tinged with lilac and roseate hues. Weight 6 lbs.

 April 18, 1840. I had the satisfaction today of identifying 

 with this species, a Medusa of which several individuals were 

 brought to me by Mr. Hyndman, just after their capture in 

 Belfast bay. On calling the attention of Mr. R. Patterson to 

 them, a reference to his notes on Medusa showed that he had 

 procured the same species at Larne (county Antrim), in May 

 1835, and June 1838 ; and again at Bangor (county Down), in 

 July 1839. As my friend could not find the species described 

 — Sars' work he had not for reference — he drew up a detailed 

 and interesting account of the animal, accompanied by several 

 characteristic sketches of it in various positions. 



Having remarked that one of my specimens, which was in a 

 phial containing 1^ ounce of sea- water, appeared as lively after 

 four days' captivity as at first, although the fluid had not been 

 changed, nor any nutriment added, I, before leaving home for 

 some days, handed it over to Mr. Patterson, that the period the 

 animal would live under such circumstances might be noted. 

 From him I learn that this individual lived thus for twelve days 

 (from the 18th to the 30th of April), and that for the first ten 

 it retained its ordinary vivacity.
