Although, as will he seen from this table, twenty-seven instances 
liave been found in which a specially marked simultaneous — 
or nearly simultaneous — migration of a species took place in 
Heligoland, and on the east coast of England, since 1868; yet 
there have been at least twenty-two remarkable migrations in 
Heligoland which cannot be correlated with any in England ; while 
the number of remarkable migrations on the east coast of England 
which have had no counterpart in Heligoland, as far as Herr Giitke’s 
statistics enable me to judge, is so large, that I have not attempted 
to collect or enumerate them, though it might be desirable at some 
future time to do so. 
I take it, that this shows that the autumnal migrants which 
arrive upon the coasts of Norfolk, Lincolnshire, Yorkshire, and 
Northumberland, are not received from Heligoland as a rule, but 
from Norway. There are six cases in which a species has appeared 
first in Heligoland in numbers, and very shortly afterwards in 
England, and these are perhaps exceptions : they are the Shore-
