C. cluthae, Brady, Crosskey, and Robertson. — Dr. Malcomson wrote 

 of this very rare species — "Although rare, this species appears to be 

 generally distributed in the deeper water." The localities in which 

 he found it were off the Antrim coast, in 60-72 fathoms, 2-5 miles 

 S.E. of the Maidens Lighthouse, and half a mile off Coalpit Bay, in 

 13 fathoms; also off White Head in Belfast Lough, in 10-18 fathoms. 

 The only other known locality in our seas is Loch P'yne, where it 

 was taken by Dr. Scott, in about 20 fathoms. It is an Arctic form, 

 in Nares' Arctic Expedition it was dredged in 80 fathoms off Cape 

 Frazier ; and in 1890 I dredged it living in two localities in East 

 Finmark, viz., in the Varanger Fiord, in 125-150 fathoms, and in 

 Bog Fiord, in 20-30 fathoms.
