30 THE MAMMALS, REPTILES, AND FISHES OF ESSEX.
the Common Dolphin never visits our coasts ; nor is
it at all unlikely that some of the Rorquals or other
Whales, absent up to the present time from our records,
may be cast ashore here at any time.
It is in the Class Pisces that the greatest additions,
however, will probably be made in the future to the
Essex Fauna; for it is quite impossible that every
species occurring on such an extensive coast as ours
can have fallen under the notice of one or two
observers ; and, in this department of science, as I
have already remarked, more than these few observers
are not forthcoming in the county.
For convenience of comparison with those counties
on the East Coast of England for which similar lists
of Fauna have been published, the following table is
appended. The last column shows the numbers for
each of the corresponding classes, generally recognised
as belonging to the British Fauna.
