CARDIUM. 35 



a very few specimens were dredged off the South Rock, 

 coast of Down, from the depth of fifty fathoms (Hynd- 

 man) ; and since the publication of the species, other ex- 

 amples have been obtained by Dr. Farren on the Irish 

 coast, by Mr. Jeffreys from Oban and other parts of the 

 western coasts of Scotland (Ann. Nat. Hist. 1847, p. 313), 

 and by Mr. M'Andrew. The following localities, noted 

 by the last-named naturalist, will serve to shew its range ; 

 Loch Fyne, in thirty fathoms, alive ; the Minch, in fifty 

 fathoms, dead ; Cape Wrath, alive, in fifty-five fathoms, 

 nine miles from land ; and off East Noss, Zetland, thirty 

 miles from land, in seventy fathoms, alive.
