The following analysis of the British, Scotch, and three 
local lists may perhaps not be devoid of interest :—

The Theridiide (the “ Micros” among Spiders) are, it will 
be noticed, by far the most numerous family in all the areas, 
being relatively highest, however, in the Edinburgh list, 
where they represent nearly 62 per cent. of the total species 
recorded for the district, as against 54 per cent. in the 
Scottish column, and 52 in the British. In Dorsetshire 
(the only county in these Islands which has been at all 
exhaustively worked) the proportion, aceording to the 
analysis at the end of the “Spiders of Dorset,” is still less, 
namely, 50 per cent. This would seem to favour the view 
expressed by Mr Cambridge nearly twenty years ago (Proc. 
Berw. Nat. Club, vii., 307), to the effect that in all probability 
these minute species proportionally increase in numbers as 
we advance northwards. The difference, however, is probably 
not so marked as was then supposed. While we may look 
to the Theridiids for most of the future additions to our list, 
several other groups, especially the Drassids and the Lycosids, 
are sure to yield a number of interesting desiderata, 
The absence from the present list of certain common 
species known to range from the South of England to the
