The species of _Lucernaria_, which has received the specific denomination of _auricula_, from its slight resemblance in form to the flower of that name, is delineated in Plate VIII., attached to a slender branch of sea-weed, just above the two large Sea-Anemonies. This species of _Lucernaria_ is generally of a light pinkish colour, and is, in general form, perhaps more like a Convolvulus than an Auricula. Two species have been most beautifully delineated in all their details by Mrs. Johnston, in her husband’s magnificent work on British Zoöphytes. These drawings are, in fact, so charmingly and, at the same time, accurately executed, that it would seem that the pencil ought to be guided by delicate female fingers when portraying these minutely-intricate and unusual forms of animal life. The exquisite drawings by Mrs. J. E. Gray, in her work on the curious molluscous animals, whose habitations alone, the beautiful sea-shells of our cabinets, were, till recently, all that was known of them, afford further evidence, if it were needed, of the aptitude of the more finely-strung female capacity for this department of scientific portraiture. The name of Mrs. Griffiths is also honourably associated with the study of natural science, especially that connected with our marine _Algæ_—a beautiful division of sea-weeds—having received its name Griffithsia, in honour of the esteemed services of that accomplished lady. The _Lucernaria campanulata_, which is of a somewhat more bell-shaped form than the preceding, is of an uniform liver colour; and in the hollow of the flower-like cup the “mouth” projects, in a square form in the centre. There are three known species of British _Lucernariæ_, which would all form highly curious objects in the Aquarium; but they are excessively delicate and fragile creatures, hanging suspended from the object to which they are attached, when taken out of the water, like a mere lump of jelly, and would doubtless be very difficult of transport, and probably not capable of retaining life in a state of confinement, except for a short time. The “compound Zoöphytes,” or, more properly, _Polyps_, as being, as it were, many creatures in one, are still more curious than the two classes just described. A common example of this class is the _Alyconium digitatum_, looking like a mass of short fingers, when the final florets are closed, as its specific name imports, being sometimes called, by the fishermen of our northern coasts, Dead-men’s-toes. Each finger-like cell contains a separate creature, whose tentacles, when expanded, form the floret, after the manner of those of the Sea-Anemonies, but yet each separate creature is vitally attached to a central polypidom, or spine, which binds the whole group into one existence.
