BRITISH SPIDERS AND THEIR DISTRIBUTION
9
Without claiming to have made any exhaustive search of the foreign
literature I have provided a fairly comprehensive list of the countries
in which our British species are known. What we see is a gradual
reduction in their numbers as we travel away from Britain eastward,
northward and southward. Unfortunately the extent of this progressive
reduction is magnified by a parallel diminution in our knowledge of
the spider faunas of the respective countries. The approximate number
of British species known in different countries abroad is indicated
below:
France, 494: Belgium, Holland and Germany combined, 453:
Denmark, 373; Switzerland, 399; Austria, Hungary and
Czechoslovakia, 410; Norway and Sweden combined, 280; Iceland,
59 out of a total of 65; Greenland, 17 out of a total of 50; Spitsbergen,
6 out of a total of 14;
Spain, Portugal and Majorca, 217; Italy, 240; the
Balkans, 200; N. Africa, 130; Azores, Madeira and Canary Islands
combined, 52; Palestine, Syria, Turkey and Iraq combined, 80;
European Russia, 322; Asiatic Russia, 202 (of which 90 extend to the
eastern coast in Kamtschatka, Amur and the Maritime Provinces);
China, 44; Japan, 30; N. America, 79.
In this review we follow the distribution of British species abroad
down to a latitude of 30 . If we pursue our search beyond this we find
they disappear entirely in the tropical regions of America, Africa and
Asia except for the species which survive in Britain solely in hot
houses. On arrival in the temperate regions of the Southern
hemisphere a few British species reappear 2 or 3 in S. America, 6 in
S. Africa, 4 in S. Australia and 8 in New Zealand.
Synonyms in brackets refer to the names employed by O. P.
Cambridge in his 1900 list.* References to subsequent additions are
added.
*Foreign arachnologists should take special note of this. When they find that
Enoplognatha caricis
Fick and
Hilaira montigena
L.K., for instance, are cited as synonyms of
E
.
schaufussi
L.K. and
H
.
frigida
Thor. respectively, this is not intended to suggest that the
species are identical. It merely records the fact that in the 1900 list such species were so
named.
