The eyes are seated on black spots. The cephalo-thorax is oval, convex, glossy, with an 
indentation in the medial line; its colour is yellowish-brown, the lateral margins being the 
darkest, and on the frontal margin, immediately above the base of each falx, there is a trian¬ 
gular spot of a red-brown hue. The falces are strong, conical, convex in front, and of a pale 
red-brown colour; they are armed with small teeth on the inner surface, and are inclined 
towards the sternum, which is heart-shaped, and has a brown tint, the margins being rather 
the darkest. The maxillae are powerful and encompass the lip, which is semicircular and pro¬ 
minent at the apex. The former of these organs are like the falces in colour, and that of the 
latter organ is dark-brown, with a tinge of red at its extremity. The legs have a yellowish- 
brown tint, and the posterior is rather longer than the anterior pair; each tarsus is terminated 
by three claws ; the two superior ones are curved and minutely pectinated, and the inferior 
one is inflected near its base. The palpi resemble the legs in colour. The abdomen is ovi¬ 
form, convex above, projecting over the base of the cephalo-thorax ; it is sparingly clothed 
with hairs, and of a dark-brown hue, the medial line of the upper and under parts being 
slightly paler, and the colour of the branchial opercula is yellow. 
The male is smaller than the female ; its cephalo-thorax is also more gibbous immediately 
behind the eyes, and, with the falces, maxillae, sternum, legs, and palpi, is of a red-brown colour, 
that of the abdomen being brown-black. The radial joint of the palpi is stronger than the 
cubital, and has a small, acute apophysis at its extremity, underneath, and a larger one in front, 
which terminates in tw r o points ; the digital joint is oval, convex and hairy externally, concave 
within, comprising the palpal organs, which are moderately developed, with a short, curved, 
obtuse process at the upper part, a small pointed spine of a semicircular form at their extremity, 
and are of a red-brown colour. 
Neriene fusca occurs on rails and under stones in Lancashire and Denbighshire. It pairs 
in the month of June.

The legs are hairy, and the posterior is longer than the anterior pair; each tarsus is ter¬ 
minated by three claws; the two superior ones are curved and slightly pectinated, and the 
inferior one is inflected near its base; the cephalo-thorax is oval, convex, glossy, with an 
indentation in the medial line; the falces are conical, convex in front, near to the base, armed 
with teeth on the inner surface, and slightly inclined towards the sternum, which is broad, 
rather convex, glossy, and heart-shaped ; the maxillae are enlarged where the palpi are inserted, 
and inclined towards the lip, which is semicircular and prominent at the apex. These
