S. I. Smith — Crustaceans of the Atlantic Coast 
the comparison be restricted either to the Decapoda proper, the 
Schizopoda, or the Cumacea. 
The numerical distribution of the above twenty-six species known 
to be Greenlandic, along the western side of the North Atlantic is 
shown in the last five columns of table (D) beyond. 
The similar distribution of the thirty-seven species common to our 
fauna and that of the European seas, and also the whole number of 
species recorded from each of the regions included in the second, 
third, fourth and fifth columns, is given in the following table, in 
which the fifth column is made to include the number of species 
found at less than fifty fathoms along the New England coast north 
of Cape Cod, while the other columns include the same regions as in 
table (A) :

Comparing the number of European species found in each of the 
four regions north of Cape Cod, with the whole number of species 
recorded from each of these regions, as given in the last line of the 
table, it will be seen that the proportion of European species is very 
nearly the same in each of the regions, while south of Cape Cod there 
is a very sudden diminution in the number of European species. 
Thirty of the thirty-seven species common to the two sides of the 
North Atlantic are known to occur on our coast in fifty fathoms or 
less, while some of the remaining sjjecies are recorded from equally 
shallow water in the European seas. This is a smaller proportion of 
deep-water species than is found among the species which are left as 
peculiar to the fauna between Cape Cod and Labrador, which shows 
that the species common to Europe and America are not predomin- 
antly deep-water species.
