Prof. Carl Eigenmann is in receipt of a Ling (Lota lota maculosa) 
from the Columbia River which does not show any specific differences 
from those of Lake Michigan. This fish is found in all three of the 
large water basins of the Atlantic slope—the Saskatchewan, St. Law- 
rence and Mississippi, and its distribution is now extended to the 
Pacifie Slope. (Science Vol. XXIII, 1894.)
