À glance at the foregoing table shows, what is remarkable enough, 
that the number of species of spiders observed in Sweden and Nor- 
way -on the one side and Great Britain and Ireland on the other is very 
nearly the same, a little above 300. As however the last mentioned coun- 
tries, from their more southerly position and warmer climate, ought pro- 
bably to possess a richer spider-fauna than our peninsula, one may perhaps 
asssume, that this latter has been more carefully scrutinized with respect 
to its arachnology than the British Isles, where accordingly a rich after- 
harvest of new species probably remains to be made. >) 
The number of species that compose the different families, is on the 
contrary very unlike within the faunistic districts in question. The Thera- 
phosoide (Mygalidæ BLACKW.), which in England are represented by Aty- 
pus piceus, are altogether absent from Scandinavia. Unless we aggregate 
Pholcus to the Scytodoidæ, that family is also unrepresented in Scandinavia. 
While Westrinc has in his Theridüde (Theridioidæ + Scytodoide NOB.) 
1) Dolomedes in BLACKWALL comprehends 3 species. 
2) Salticus in BLACKWALL comprehends 17 species. 
3) In some papers that have since appeared, CAMBRIDGE and BLACKWALL 
have indeed considerably augmented the number of known spiders in these islands. 
In Sweden also several new forms have in the meantime been observed, but not 
yet published; some of these we shall have occasion in the following pages to mention.
