other material came from Eastport, Maine, summer, 1893, 2 speci- 

 mens; Treats Island, Eastport, Maine, seine on gravel beach, collected 

 by H. F. Moore, July 28, 1893, about 150 specimens; Long Beach, 

 Grand Manan, New Brunswick, collected by M. J. Rathbun, August 

 16, 1898, 10 immature specimens ; Speedwell stations 1-5*, 23-30*, 32*, 

 154*, 156*, 161*, 165*, 167*, 181*, 203-207*, 216*, 218*; Bache sta- 

 tions 29*, 63-65*; Labrador; Albatross station 2437*; Cape Cod Bay, 

 Mass.,* 27 fathoms. All the material marked * was identified by S. I. 

 Smith and is probably included in his records (1879). 



Distribution. — Smith (1879) gave a full list of the localities at 

 which this species was collected on the east coast of the United States. 

 References to records subsequent to Smith's paper are given in the 

 synonymy. These later records and the material here recorded add 

 very little to Smith's account and merely serve to emphasize the fact 

 that this species is common off the east coast of the United States 

 between Woods Hole and the northern border in depths down to 100 

 fathoms where the bottom is suitable, that is, where algae and zostera 

 are not present. The species does not appear to extend farther south 

 than Woods Hole ; at least I can trace no more southerly records. In 

 the northerly direction it extends to Canada, Greenland, Iceland, and 

 across to Scandinavia.
