though without bright markings, sometimes varied with brown

Remarks. — Originally described from Great Egg Harbor, 

 where it was found with I do tea halthica. It ranges north to 

 Massachusetts, and south to Florida and the Bahamas. It lives 

 in tide-pools, among eel-grass or algae, sand, gravel, etc. It has 

 "been taken from four and one-half to eighteen fathoms in depth. 

 Verrill says it lives among the Corallina and other algae in the 

 tide-pools. Its colors are equally variable with those of the other 

 species, and are often variously shaded l)rown, dull reddish or 

 light red, colors well adapted to blend with the colors of the 

 ■Corallines. Mr. Witmer Stone secured it at Point Pleasant.
