es, save the little common lizard, Lacerta agilis, and
a few frogs on the mountain-tops--how they got there I cannot
conceive. And you will, of course, guess, and rightly, that the
reason of the absence of reptiles is: that Ireland was parted off
from England before the creatures, which certainly spread from
southern and warmer climates, had time to get there. You know, of
course, that we have a few reptiles in England. But you may not be
aware that, as soon as you cross the Channel, you find many more
species of reptiles than here, as well as those which you find here.
The magnificent green lizard which rattles about like a rabbit in a
French forest, is never found here; simply because it had not worked
northward till after the Channel was formed. But there are three
reptiles peculiar to this part of England which should be most
interesting to a Hampshire zoologist. The one is the sand lizard
(L. stirpium), found on Bourne-heath, and, I suspect, in the South
Hampshire moors likewise--a North European and French species.
Another, the Coronella laevis, a harmless French and Austrian snake,
which has been found about me, in North Hants and South Berks, now
about fifteen or twenty times. I have had three specimens from my
own parish. I believe it not to be uncommon; and most probably to
be found, by those who will look, both in the New Forest and
Woolmer. The third is the Natterjack, or running toad (Bufo
Rubeta), a most beautifully-spotted animal, with a yellow stripe
down his back, which is common with us at Eversley, and common also
in many moorlands of Hants and Surrey; and, according to Fleming, on
heaths near London, and as far north-east as Lincolnshire; in which
case it will belong to the Germanic fauna. Now, here again we have
cases of animals which have just been able to get hither before the
severance of England and France; and which, not being reinforced
from the rear, have been forced to stop, in small and probably
decreasing colonies, on the spots nearest the coast which were fit
for them.
I trust that I have not kept you too long over these details. What
I wish to impress upon you is that Hampshire is a country specially
fitted for the study of important bio-geological questions.
To work them out, you must trace the geology of Hampshire, and
indeed, of East Dorset. You must try to form a conception of how
the land was shaped in miocene times, before that tremendous
upheaval which reared the
