Coleoptera”) is 3287, of which about 1840, or 56 per cent, 
are enumerated in Dr Sharp’s Scottish list (Scot. Nat., i-vi), 
including the additions by Messrs Lennon and Douglas 
recently published in the Annals of Scottish Natural 
History. Of the 129 Land and Fresh-water Mollusca 
given in the Conchological Society’s latest list, 105, or 
81 per cent, are known to occur in Scotland (Roebuck’s 
“Census,” etc). 
From the above it appears that a much larger proportion 
of Lepidoptera and Coleoptera fail to reach Scottish territory 
than is the case with the terrestrial mollusca. Now, in the 
matter of distribution, the spiders, we take it, are more likely 
to be in agreement with the insects than with the molluscs. 
On this basis we may venture to predict that the number of 
Scottish Araneidea is not less than from 320 to 345, that is, 
from 60 to 65 per cent. of the British species; and seeing 
60 per cent. or thereby of the known Scottish Macro- 
lepidoptera have been taken in the vicinity of Edinburgh, 
there can be little doubt that when the district has been 
equally well worked for spiders the list will rise to con- 
siderably over 200 species. 
The only Scottish districts for which anything like 
adequate lists of spiders have been hitherto published are 
the north-east corner of Berwickshire, in which Dr Hardy 
of Oldcambus has laboured;! and “Dee,” which has been 
investigated by Professor Trail of Aberdeen.” The number 
of species (after allowing for some slight adjustments) 
recorded for Berwickshire is 116, and for “Dee” 115, as 
against the 175 now recorded for Edinburgh.
