Habitat. — This species was first dredged in British seas by Dr. Gwyn Jeffreys off 

 the Hebrides in 1866, and often subsequently in various grounds off Shetland in depths 

 ranging from 75 to 100 fathoms, and chiefly on muddy sand. The same persevering 

 explorer found it off the west coast of Ireland (Yalencia Island). It extends into the
