previously in Britain. It also turned up at the roots of grass
on the Undercliff at Walton. The thicket at West Mersea was
remarkable for the abundance of certain Epeirids, viz., Epeira
marmorea pyramidata, E. ocellata and Tetragnatha nigrita. None
of these had I ever seen in such numbers before, and most
examples of the second were of a colour variety which was
entirely new to me. The ground colour of the dorsum is a
uniform russet brown with the "folium" outlined with a narrow
black line. As this form seems to deserve a name I call it var.
brunnea.
