262 HISTORY OP BEIT1SH ZOOPHYTES. 



Hab. Common in Zetland, on the broad leaves of Fuci, 

 Dr. Fleming ; Donaghadee, Templeton ; Hellswick Voe, 

 Zetland, dredged by Prof. E. Forbes and Mr. M'Andrew; 

 Ardrossan, Mr. Joshua Alder; Saltcoats, D. L., jun. 



It is found that this is synonymous with Lucernaria 

 qiiadrangularis. " The peduncle of the body is produced ; 

 tufts of tentacula in pairs, about a hundred in each." The 

 body is bell-shaped, quadrangular, concave : it generally 

 hangs downwards. The colour is dark brown, though, from 

 what Templeton says, it may have other hues. " When at 

 rest," he says, " it assumes very much the form of a com- 

 mon drinking-glass, and is exceedingly conspicuous from its 

 beautiful rose-tint." Our Ayrshire specimens are so far 

 from being conspicuous, that we never observed it till it 

 was detected by the more practised eye of Mr. Alder, when 

 residing at Ardrossan for a short time; and we afterwards 

 found it when we knew its appearance. It gives out, in 

 the dark, when irritated, bright flashes of bluish phospho- 

 rescent light. 



2. LUCERNARIA AURICULA, Montagu. (Plate XI Y. fig. 

 49.) 



Hab. Coast of Devonshire, Montagu; on Fuci, near 

 low-water, on different parts of the coast, Dr. Fleming.
