Remarks. — This species was originally described from Great 

 Egg Harbor. It is met with in either a free state among 

 various marine animals, such as bryozoa, hydroids, etc., and 

 among sea-weeds or other marine vegetable matter. It also 

 lives in soft tubes, often occurring on eel-grass near the roots 

 of the plant.
