sides of the body. The color is dull yellowish gray, and altogether 
it is not an attractive object. 
The Orange-streaked Anemone, ( Sagartia lucie ), is now the 
most abundant species in rocky tide-pools of Long Island Sound. 
It appears to have been introduced upon oyster shells from 
the south, for previous to 1892 it was unknown along our coast. 
In that year it was found by Miss L. L. Verrill, near New Haven, 
and it has gradually spread northward, reaching Salem, Massa- 
chusetts, in 1901; beyond which place it appears not to exist. 
It is only about one-quarter of an inch wide and three-eighths 
high, and there are about forty-eight slender tapering tentacles. 
The body of the anemone is olive green or brown, usually with 
twelve fine longitudinal orange, or lemon yellow, streaks; while the 
tentacles are ight brown, almost white. 
The best description of this anemone is that of Mrs. Gertrude 
C. Davenport in the “Mark Anniversary Volume,” p. 157-144. She 
discovered that the anemone often splits into two, and the halves 
soon separate, and grow to their original size. Iragments may 
also be separated from the base, and then regenerate into new 
individuals. 
The Crimson Anemone, ( Tealia crassicornis ), is of moderate 
size, being about two inches high and one and one-half in diame- 
ter. It has about 160 blunt tentacles, and the body is covered with 
tubercles. It is found in tide-pools, and upon rocky bottoms 
north of Cape Cod, and may be recognized by its rich cherry-red 
or crimson color, although some specimens are mottled with red 
and bluish-green. A drawing of this species is given in Agassiz’s 
“Seaside Studies,” p. 13, under the name of Rhodactinia davisit. 
The Parasitic Anemone, ( Hdwardsia leidyi). Sea anemones 
live in almost every conceivable situation upon rocky shores, in 
muddy or sandy beaches, or upon shells which are being carried 
about by hermit crabs, while others float over the ocean, or swim 
freely about. Some are even parasitic, and among these Ndwardsia 
leidyi is most remarkable. It lives within the transparent Rain- 
bow Jelly ( Mnemiopsis leidyi. See page 39), and its long, dull 
pink, threadlike form caused it to be mistaken for a worm. 
It is about one and one-half inches long and only about one- 
sixteenth of an inch in diameter, and there are sixteen blunt
