Chapter LXIV: Appendix

Mr Dixon has kindly sent me a considerable quantity of
shell-sand from Gairloch shore. I have examined it, and
found the following sea-shells. Those which were somewhat
plentiful are marked with an asterisk. It would be easy to
name some additional shells which will probably be found on
Gairloch shore, though they were absent from the sand
examined; but I have preferred not to do so.

The following are a few notes on the land and fresh-water
shells:--

Pisidium fontinale--Occurred in the shell-sand, having been
washed down to the sea by streams. I found a fine
variety--perhaps _var._ pulchella--in a pond between
Gairloch and Loch Maree.

Ancylus fluviatilis--Several among the shell-sand.

Succinea putris--Two among the shell-sand.

Vitrina pellucida--Not uncommon under stones, &c.

Zonites cellarius--Two among the shell-sand. I found it also
living among stones.

Zonites nitidulus, _var._ nitens--Living among stones, &c.

Zonites purus--Among dead leaves.

Zonites radiatulus--Two among the shell-sand. It is probably
not rare under stones, &c.

Zonites fulvus--Among dead leaves.

Helix nemoralis--Among the shell-sand.

Helix rotundata--Under stones.

Pupa umbilicata--Under stones. The variety edentula occurs.

Balia perversa--Common at the foot of walls near the parish
church, and probably in other places.

Clausilia rugosa--Under stones, &c.

Cochlicopa lubrica--Three among the shell-sand.
