262 HISTORY OF BRITISH ZOOPHYTES. 
Hab. Common in Zetland, on the broad leaves of Fuci, 
Dr. Fleming; Donaghadee, Templeton; Hellswick Vée, 
Zetland, dredged by Prof. H. Forbes and Mr. M‘Andrew ; 
Ardrossan, Mr. Joshua Alder; Saltcoats, D. L., jun. 
It is found that this is synonymous with Lucernaria 
quadrangularis. ‘“'The peduncle of the body is produced ; 
tufts of tentacula in pairs, about a hundred im 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 beimg 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 avuRicuLa, Montagu. (Plate XIV. fig. 
4:9.) 
Hab. Coast of Devonshire, Montagu; on Fuci, near 
low-water, on different parts of the coast, Dr. Fleming.
