 S.E. of the Maidens Lighthouse, and half a mile offCoalpit 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 Fyne, 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.
