by the steamer "Albatross," September 6, 1884, in Lat. 39° 3' 15" N. and 

 Long. 70° SCy 45" W., at a depth of 1537 fathoms. This is well preserved, and 

 throws additional light on the external characters of the species ; the fins, 

 especially, are more nearly perfect. Measurements are given alongside of those 

 taken from the " Blake " specimen.
