Entelecara errata, sp.n. Figs. 18, 19, 20, 21. 



Entelecara omissa, Cambr., Proc. Dors. F. Club, 



Vol. XXIV., pp. 149, 156 and postea, and 167, 



pi. A, fig. lOd.) (1903). The other figs, in 



pi. A are E. omissa, Cambr. 



The occurrence in plenty of Entelecara omissa, Cambr. 



in Wicken Fen has enabled me to compare that species 



more fully with the examples taken in Cumberland by 



Dr. Jackson on the top of Scafell Pike and Bowfell, and 



supposed at the time to be those of Entelecara omissa, 



Cambr. We have now concluded that, though nearly 



allied, the Cumberland examples are of a different 



species. (For a description of which see postea, 



p. 134.)
