This species must be much more generally distributed than was at 

 one time supposed, for in 1883 the Talisman dredged it off the west 

 coast of the Soudan. The Lightning and Porcupine only found frag- 

 ments, though Jeffreys remarks in one case {Lightning, 1868, north of 

 Hebrides, St. 5) the pieces were quite fresh and united by the carti- 

 lage.* Li7na excavata has usually been considered to be confined to 

 almost Arctic seas. 



Station VII. 444 fathoms. One living.
