tached to the under side of boulders that have a cavity 
beneath them, and is well adapted to the aquarium, where it — 
very soon becomes perfectly at home, and expands almost 
constantly. Inhabiting the same region with this there is 
another more rare species of Sagartia,* which is duller in 
color and less graceful in form, which lives buried up to its 
tentacles in eavek: 
Besides the species already described, there are several 
others that are less conspicuous, which inhabit the New Eng- 
land coast, several of which live buried in sand or mud, like 
many worms, and only protrude their tentacles at the sut- 
face. These kinds are usually long and slender, and taper 
at the base instead of having a flat adhe. disk. Farther 
southward on the Garoa.. coast there are several other 
peculiar species, some of them beautifully colored, and also 
several species of true corals, the animals of which closely 
resemble the Sea-anemones in structure and habits. 
pretty species of coralț is even found on the southern coast 
of New England. This is found just below low-water 
encrusting stones and shells, and forming little irregu 
masses of coral, covered with star-like cells or igi a 
are about an eighth of an inch across. The polyps, W 
life rise abars these stellate cups, are colorless and 
transparent, resembling, in nearly all respects, 
Actinias. This coral lives well in confinement, and 
readily upon bits of oyster, in the same manner as 
anemones.
