378 Eolidia despecta. 



jelly. If unravelled, the chain would measure many inches ; 

 but the separate links are only about one tenth or one eighth 

 of an inch long, and contain, each of them, numerous ova. 

 (Jig, 35.) These are roundish or oval, with a rough irre- 

 gular outline ; two, or at most three, contained within their 

 own little pellicle of jelly, which again lies immersed in the 

 common mass. 



Eolidia papillosa is the largest species of its genus. Ac- 

 cording to Dr. Fleming, it is common on our shores, among 

 sea-weeds, near low water ; but it appears, nevertheless, to 

 have been seldom seen or described. It was first ascertained 

 to be a native by the Rev. Mr. Cordiner, a Scotch clergy- 

 man, whom Pennant engaged to travel among the Western 

 Isles of Scotland, to delineate their romantic and rugged 

 scenery. Dr. Turton next noticed it " on the Mumble 

 Rocks," and introduced it into his compendium of our fauna, 

 under the name of Doris ttermigera; and it will be found 

 among Professor Jameson's list of the Fermes of the Firth of 

 Forth. (Wern. Mem., i. 556.) Montagu detected it on the 

 shores of Devon ; and has described it, with his usual accu- 

 racy, in the 11th volume of the Linruean Transactions, adopt- 

 ing the name which Miiller had applied to this snail, under 

 the conviction that it was identical with the Z/imax papillosus 

 of Linnaeus. That synonyme has been erroneously referred 

 by Lamarck to his E N olis CuvienV; which is quite distinct 

 from the one before us, and has not been observed on the 

 British coast.
