seven and a half feet across the disk and with tentacles 

 more than a hundred feet long. This form is found in 

 the cold waters north of Cape Cod and is common along 

 the New England coast. Along the Long Island coast it 

 is found only in the spring and early summer and is of 

 much smaller size. The anemone to be searched for in a 

 sandy environment is the Sand Anemone (Holocampa 

 producta) which is characteristic of sandy and muddy 

 beaches from Cape Cod to South Carolina. On sandy 

 beaches it is found buried in the sand with only the ten- 

 tacles exposed, but it is also found under rocks at low- 

 tide mark. This species is dull yellowish gray in color. 

 It is three or four inches long and half an inch in diame- 

 ter, but can contract to a length of about two inches when 

 disturbed. 



Of the brachiopods or Lamp Shells no representative 

 is found along our northeastern sandy shore, but a Lin- 

 gula-like form (Glottidia pyramidata) ranges from Chesa- 

 peake bay to Florida and is very abundant off the coast 

 of North Carolina on shoals exposed at low tide, half- 

 buried in the sand. The valves of the shell are tongue- 

 shaped and horny. The shell is drawn down into the 

 sand by contraction of the stalk or pedicle. A great many 

 species of worms are inhabitants of sandy shores but only 

 a few will be touched upon here. A relative of the Clam 

 Worm {Nereis wrens), which is so common on muddy 

 beaches, is found along the Middle Atlantic coast on 

 sandy shores. This form (Nereis limbata) is recognized 

 'by its small size (6 inches long) and its horny, yellow 

 colored teeth. The Lug Worm (Arenicola marina) which 

 is of economic importance because of its use by fisher- 

 men for bait, makes burrows 18 to 24 inches deep on 

 sandy and muddy southern shores and on the west coast
