THE TRANSLUCENT ANEMONE. • 
83 
This species I know only by the descriptions and figures 
of Mr. Joshua Alder, who has kindly put into my hands, 
not only the published ‘‘ Catalogue of the Zoophytes of 
Isorthumberland and Durham,” in Avhich it first received 
a name and place among our Anemones, but additional 
notes in MS., and several original drawings. All these 
I have used in my diagnosis and figure. Tlie name 
“ i^ellucida," originally applied to this little animal, 
having been preoccupied, Mr. Alder proposes that it should 
be called “ jyura.'^ 
Little is known of its history. Its discoverer observes 
of it, — “ It has occurred to me two or three times at 
Cullercoats, on old shells, — crusted shells of Fiisus anti- 
quus from deep wate].*, — nestling among the Serpulje and 
Barnacles with which they were covered. It is so incon- 
spicuous, when contracted, as to elude observation ; and it 
was not till the shells had been some time in sea-water, 
and the Actinia became expanded, that its presence was 
detected. A* specimen kept in a va.se was very restless, 
shifting its place continually, and often changing form.” 
It seems to be somewhat rare. Mr. Alder has seen but 
three specimens. Mr. B. Ilowse has obtained it once or 
twice from the five-men boats, on the same coast. Ills 
specimens were slightly larger than INIr. Alder’s.
