These fifteen peculiar fishes differ from each other and from 
all British and continental species, not in colour only, but in 
such important structural characters as the form and size of the 
fins, the number of the fin-rays, and the form or proportions of 
the head, body, or tail. They are in fact, as Dr. Gunther 
assures me, just as good and distinct species as any other re- 
cognised species of fish. It may indeed be objected that, until 
all the small lakes of Scandinavia are explored, and their fishes 
compared with ours, we cannot be sure that we have any peculiar 
species. But this objection has very little weight if we consider 
how our own species vary from lake to lake and from island to 
island, so that the Orkney species is not found in Scotland, and 
not one of the peculiar British species extends to Ireland, which 
has no less than six species altogether peculiar to it. If the 
species of our own two islands are thus distinct, what reason have 
we for believing that they will be otherwise than distinct from 
those of Scandinavia ? At all events, with the amount of evi- 
dence we already possess of the very restricted ranges of many of
