THE MARINE AQUARIUM. ai 
usually after a storm, it is a flat-looking, smooth mass, of 
a brown tint, delicately striped with yellow and white. 
After a few days’ residence in the tank, it begins to expand, 
and rises to so tall a figure, especially in the twilight, 
that it appears quite a different creature to that introduced 
afew days before. In fact, its actual bulk is increased 
vastly by expansion. It is constantly expanded. 
A. Bellis is another good species. It is a delicate 
pink and brown and pink and white anemone, and cer- 
tainly does resemble a daisy very closely indeed. Though 
much prized it is not rare. Mr. Lloyd usually has abun- 
dance of them on sale, at a shilling each, and a few should 
be used to give variety to the collection. In newly-made 
marine-water it will not do at all; but if it falls into the 
possession of an aquarian who has no ripe tank at hand 
for it, it may be kept for weeks in a shallow pan. 
If anything goes wrong with this kind, it throws out a 
number of white threads, and shrinks out of form, and 
perishes in a few days; but once obtained in a sound 
state, and carefully treated at the outset, it is as hardy as 
mesembryanthemum, and more readily expanded at all 
seasons than most of its compeers. 
Actinia Gemmacea.—This is a delicately-constituted 
anemone, that displays itself freely only in the most pure 
sea-water, in which there is abundance of oxygen. It is 
quite unfit for early experiments, but well repays the 
trouble it occasions when it can be successfully kept. A 
few weeks since I had the pleasure of witnessing the birth 
of a large ciuster of this pretty anemone in the extensive 
collection of Mr. Lloyd, at Portland Road. To the
