recorded above has been seen by Mr. Cambridge. 
Diplocephalus castaneipes Sim. 
Three adult females, June oth, at the roots of herbage 
in a dried-up spot on the slope between Middle 
House and Malham Tarn, but nearer the former 
place. 
This spider was first met with as a British species on 
the summit of Snowdon, where both sexes were 
taken by Dr. Jackson in 1905 (‘ Proc. Dors. Field 
Club,’. Vel. XX VI1., 1906; ip. O1).) “litghas: sites 
been found in the other three countries of the 
British Isles. 
Diplocephalus protuberans Camb. Fig. 1. 
An adult pair at the roots of grass on the left bank 
of Ainley Place beck, in Clough House Wood, 
Slaithwaite, May roth, and a few days later, a couple 
of females in the same place. Originally in the 
male sex, described and figured by the Rev. O. 
Pickard Cambridge, in ‘ Proc. Zool. Soc.’, London, 
1875,,p. 216, pl.) XXX. fig. 24, sub. Bygone 
protuberans. A single male of this spider, which 
had previously occurred in France, was, when 
found by Mr. R. S. Bagnall, in December 1906, 
among moss at Gibside, Durham, new to Britain. 
This example is recorded by Dr. Jackson, in ‘ Proc. 
Chester -Soc::}-.1907, "Pi-6;, pr. 3, and the ymale 
palpus is there figured in various positions, Plate 
I., figs. 10-15. The above, therefore, is the second 
occurrence of the species, but the first record of the 
female in Britain. 
The females I took apparently agree with the des- 
cription given by Simon in his ‘ Arachnides de 
France, Tome V., Partie 3 :— Epigyne: a semi- 
circular brownish plate, rugose and ciliate, con- 
vex in front, and a little depressed behind, en- 
tirely divided by a slender longitudinal strie and 
marked on each side with an oblique curved depres- 
sion not reaching the margin,’ but certainly no one 
would recognise the species from his figure, which 
is the only one extant. JI venture, therefore, to 
append a drawing of the epigyne, which is very 
distinct and characteristic, and not at all likely 
to be confounded with that of any other British 
spider. '
