Argyroneta aquatica Latr. The ‘ Water-spider,’ numerous 
adult females and immature examples of both sexes in the

dikes and pits of the fen, which were not searched.

and at the Fen Cottage. 
Cicurina cinerea Panz., sub. Coelotes 1immaculatus Camb., 
‘Spiders of Dorset,’ p. 169. One female in the fen. This 
synonym, which does not appear in his ‘ List of British and 
Irish Spiders,’ has been kindly communicated to me by the 
Rev. O. Pickard Cambridge. Not a common spider but widely 
distributed.

Drove, one male on left of fen, June, 1914. Widely distri-

parts of the fen, and amongst heaps of sedge litter.

but not recorded. 
C. incultus sp. nov. An adult female, July ,1913, from the 
right of the fen. The example was posted to Cracow, to obtain 
the opinion of Professor Kulczynski, but was unfortunately 
lost in transit. It had, however, been seen by both the Rev. 
O. Pickard Cambridge and Dr. Jackson. As it will probably 
turn up again if looked for in autumn, I describe and figure 
it below.
