Dr. Stephensen says that this species is widely distributed in the 

 northern Atlantic north of a line from the Bay of Fundy and West 

 Greenland about 64° N. to South Iceland and British and Danish 

 waters. It is probably circumpolar. S. J. Holmes recorded it from 

 Monterey Bay, Calif. E. Gurjanova recorded it from the Sea of 

 Japan in 1938. There are specimens in the U. S. National Museum 

 from Vineyard Sound off Marthas Vineyard. The present records 

 are the first for Alaska. This species reaches a length of 23 mm. The 

 lowest recorded depth appears to be 475 to 575 m. (Norman, 1895, 

 p. 484).
