OUR SEA-ANEMONES. 259 
spicuously banded with opaque-white, and upon the disk 
there are usually six or twelve white lines, radiating from 
the mouth to the bases of the tentacles. Most of the tentacles 
usually have a white, heart-shaped spot upon the inner side 
of their bases. This pretty Actinia is very common at 
Eastport and vicinity, and has been found at Cape Elizabeth, 
Maine. In the latter locality the specimens were half-buried 
in sand at the bottom of a rocky pool near low-water mark. 
Doubtless it will be found upon all parts of the rocky coast 
of Maine. In confinement it expands most freely in the 
evening. It feeds, like the other species, upon all sorts of 
mollusca and crustacea that come within its reach. It brings 
forth living young, often of considerable size, which emerge 
at irregular intervals from the mouth, sometimes singly, 
sometimes in large numbers. It does not grow so large as 
the preceding, the body seldom becoming more than two 
inches high and one in diameter, but having more than twice 
that diameter across the expanded tentacles. 
The Red Sea-anemone* is unquestionably the most beau- 
tifully colored and showy of all our northern Actinias ; but, 
although very changeable in shape, it lacks the elegant 
forms assumed by other species. The body usually forms, 
in expansion, a low cylinder, broader than high, with a 
broad disk, surrounded by a moderate number of large, 
tather short, tapering or blunt tentacles. The exterior of 
e body is sometimes nearly smooth, but at other times 
Shows a few, rather inconspicuous, warts or suckers scat- 
: ig over the surface. The colors are extremely varia- 
le. The shore specimens are mostly irregularly mottled 
With deep brownish red, and dull greenish, while the ten- 
tacles are pinkish, banded with opaque-white. The disk is
