joint is nearly equal in length to the digital, and enlarges 
gradually from its hinder to its fore extremity, where its size 
is the same as that of the base of the digital joint. Their 
colour and armature are like those of the legs. 
The falces are moderately strong, rather long, perpendicular, 
and a little divergent at their extremities, and their colour is 
yellowish suffused with sooty brown. 
The mawxille, labtum, and sternum are similar in colour to 
the falees. The mazille are rather strong, short, inclined to 
the labium, but straight. 
The abdomen is oval, thinly clothed with hairs, and of a 
sooty-black colour, strongly tinged with dull yellowish on the 
sides and underneath. The form of the genital aperture 
(fig. 38, c) is characteristic and conspicuous. 
A single adult female of this species was found, on the 14th 
of June 1876, among dead leaves in a wood at Bloxworth. 
It differs rather from the typical Walckenaére in the form of 
the maxille, but in no other respects sufficiently to justify its 
removal from that group. 
Genus Linypuia, Latr. 
Linyphia? incerta, sp.n. (Pl. XI. fig. 2.) 
Adult female, length 1 line. 
This spider is very nearly allied to LZ. oblonga, Cambr. 
(Trans. Linn. Soc. xxvii. p. 433). It is, however, larger and 
darker-coloured, though resembling that species very closely 
in general form and appearance. It may be distinguished 
readily by the larger size of the eyes, which, instead of being, 
as in L. oblonga, all of a pearly-white colour, have those of 
the fore central pair of a dark hue. The relative position of 
the eyes is the same in both species. The height of the 
clypeus exceeds half that of the facial space. 
The legs are long, slender, their relative length being 
4,1, 2,3. They are furnished with bristly hairs and long, 
fine, prominent spines ; the length of the spine near the poste- 
rior extremity of the tibiee of the fourth pair is equal to (if it 
does not exceed) three times the diameter of the joint. 
The palpi are rather long, slender, and furnished with hairs 
and spine-like bristles. 
The falces are long, strong, prominent at their base in 
front, and strongly directed backwards towards the mawille. 
These, as well as the labéwm and sternum, are similar to those 
of L. oblonga. 
The abdomen is of an oblong-oval form, rather flattened, 
and projects considerably over the base of the cephalothorax.
