sides of the body. The color is dull yellowish gray, and altogether 

 it is not an attractive object. 



The Orange-streaked Anemone, (Sagartia luciw ), 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 1S02 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 

 iilgli, 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 light brown, almost white. 



The best description of this anemone is that of Mrs. Gertrude 

 C. Davenport in the "Mark Anniversary Volume," p. l.''!7-144. She 

 discovered that the anemone often splits into two, and the halves 

 soon separate, and grow to their original size. Fragments may 

 also be separated from the base, and then regenerate into new 

 individuals. 



The Crimson Anemone, fTealici crasskornisj, is of moderate 

 size, being about two inches high and one and one-half in diame- 

 ter. It has about 100 blunt tentacles, and the body is covered with 

 tabercles. It is found in tide-pools, and upon rocky bottoms 

 north of Cape Cod, and maj' be recognized by its rich cherry-red 

 or crimson color, although some specimens are niottled with red 

 and bluish-green. A drawing of this species is given in Agassiz's 

 "Seaside Studies," p. 13, under the name of Rliodactinia davisii. 



The Parasitic Anemone, f Edivanlsia leidijij. Sea anemones 

 live in almost every conceivable situation upon rockj' 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 Edivardsia 

 Icidiji is most remarkable. It lives within the transparent Rain- 

 bow Jelly (Mneniiopsis leidiji. See page Si9J, 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
