s, and s'), is a little less elongated than in the next species, not attain- 

 ing the middle of the cilia. 



Length 6 mm ; breadth 2.3 mm . The color is uniform, dull, usually

This species was described by Say from Egg Harbor !, New Jersey, 

 where specimens were also collected by Professors Verrill and Smith, in 

 April, 1871, among eel-grass. It has also been found at Savin Rock !, 

 near New Haven, and Noank Harbor!, on piles and among eel-grass; at 

 Vineyard Sound!; Mass., at Provincetown!, Mass., near Cape Cod in

This species closely resembles the preceding, and may be recognized
