(C) SaLt-waTER FIsHES OF THE ATLANTIC Coast. 
In the far north, where the opposite continents converge, the faunas of 
the coast reflect the geographical fact. The species of the two coasts are 
identical or much alike. The Sculpins or Cottids and the Cods or Gadids 
are predominant forms; a little further southward the Herrings or Clupeids 
and the Flatfishes or Pleuronectids share the waters with them. They are 
the chief piscine representatives of the ARcric Fauna. Around the penin- 
sula of Nova Scotia and in neighboring waters may be found many of the 
fishes of the Arctic region in association with others from the south. This 
assemblage extends southward to Cape Cod with’ successive additions from 
the south and losses to the north. The entire area is known as the Nova 
Sco1tan or Acapian Fauna. From Cape Cod to Cape Hatteras is found 
another aggregate of fishes, which, towards the north, shows a greater reten- 
tion of northern forms, and towards the south, a large infusion of warm-water 
types. The aggregate has been called the Vircintan Fauna. Then be- 
tween that fauna and the coralliferous coast of Florida intervenes an area 
whose fishes are mostly the same as the Virginian, but a still greater admix- 
ture of warm-water species is developed and still more of the northern forms
