364 REPORT OF COMMISSIONER OF FISH AND FISHERIES. 



bor and near New Haven light. The body is three or four inches long 

 when extended, and an inch or more in diameter, and is very changeable 

 in form. The surface is nearly smooth, slightly sulcated lengthwise, 

 and the color is usually pink, or pale flesh-color, translucent. The 

 tentacles are numerous, short, tapering, pale greenish olive, with a dark 

 band around the base, connected with a dark line radiating from the 

 mouth. Toward the upper part of the body the surface is somewhat 

 wrinkled and is capable of attaching grains of sand to itself. When 

 thrown up by the waves it contracts into a globular or pyriform shape 

 and " somewhat resembles a boiled onion or turnip."
