WHEN, HOW, AND WHENCE?
Fig. 4. The percentage of the Faroese fauna of Coleoptera (COL), Araneae (ARA), Lumbricidae (LLÍM) and
Gastropoda (GAS, slugs/snails) found in the neighbouring areas. Figures in parenthese indicate the known number
of species of the respective groups in these areas. Areas included are the Outer Hebrides, the Scottish Mainland,
the Orkney Islands, Shetland, western Norway (the counties Sogn og Fjordane, Hordaland, and Rogaland, i.e.
approximately the stretch between Álesund in the north to Stavanger in the south), and Iceland. Data on the groups
from: Coleoptera: Bengtson 1981 and references therein, Waterston 1981, Araneae: Ashmole 1979, Bengtson and
Hauge 1979 and references therein, Waterston 1981; Lumbricidae: Enckell and Rundgren 1983 and references
therein, Gerard 1964, Waterston 1981; Gastropoda: Solhøy 1981 and references therein, Waterston 1981. For Co-
leoptera, the total species number in the British Isles is about 3800; the Faroese species have been checked as to
their occurrence in Scotland.
