water attached to piling, sea weed or Eel Grass and 

 often coated with small bits of sea weed, sand, etc. 

 This species will live throughout the winter un- 

 less frozen by the ice; those living in deeper water, 

 where there is little danger of ice, usually reach a 

 larger size. The average size is about an inch in 

 diameter. Its usual color is pale olive green. Maine 

 to North Carolina; often abundant in New Jersey. 



Molgula arenata Stimpson 



PLATE XXVIII. Fig. 3 



Flatter than the above and with shorter siphons; 

 usually heavily coated with sand grains which ad- 

 here tightly to the tunic or body. Lives unattached. 

 Found in slightly deeper water than M. manhattensis 

 and not nearly as common. Some specimens dredged 

 at McCrie Shoal, 7 miles off Cape May, in 21 feet 

 of water, mark the farthest south that this species 

 has vet been found.
