S. 1. Smith — Crustaceans of the Atlantic Coast. 
Of the thirty-six Greenland species, six are not yet recorded from 
outside the Greenland seas, so that out of thirty species, twenty-six, 
or about eighty-seven per cent., are known upon the eastern coast of 
North America from the Gulf of St. Lawrence southward; while 
twenty-four species, or eighty per cent., are known in the European 
seas. An uncompleted examination of the Amphipoda gives results 
entirely in harmony with those above derived from the Thoracostraca, 
so that it is certainly safe to assert that, at least as far as the Mala- 
costraca are concerned, the marine fauna of Greenland is essentially 
the same as that of the arctic seas of both Europe and America, or, 
in other words, it is only a part of the great arctic, circumpolar fauna. 
That the fauna of the Greenland seas should have its closest relations 
with the fauna of the North American coast proper, rather than with 
that of Europe, is what might be expected from the geographical 
position of Greenland and the fact that the waters of the northern 
part of the North American coast are more arctic in temperature 
than the waters upon the coast of Europe.
