the medial line; the falces are powerful, conical, convex in front, near the base, armed with 
teeth on the inner surface, and inclined towards the sternum, which is heart-shaped; the 
maxillae are strong, and inclined towards the lip, which is semicircular and prominent at the 
apex. These parts are of a brown colour, the sternum being the palest, and the falces, 
maxillae, and lip having a tinge of red. The legs are long, provided with hairs and a few fine 
spines, and of a pale red-brown hue; the anterior and posterior pairs are equal in length; 
each tarsus is terminated by three claws; the two superior ones are curved and pectinated, 
and the inferior one is inflected near its base. The palpi resemble the legs in colour. The 
abdomen is oviform, rather convex above, and projects over the base of the cephalo-thorax; 
it is thinly clothed with hairs, glossy, and of a brownish colour faintly tinged with green, and 
has a series of obscure, angular lines of a pale yellowish-brown hue, whose vertices are 
directed forwards, extending along the middle of the upper part; the sexual organs have a 
dark red-brown tint; and the colour of the branchial opercula is dull yellowish-brown. 
The male is rather smaller than the female, but it resembles her in colour. The cubital 
and radial joints of its palpi are short, the latter being much the stronger; the digital joint is 
somewhat oval, with a large lobe on the outer side, near the upper part; it is convex and 
hairy externally, concave within, comprising the palpal organs, which are highly developed, 
complicated in structure, with several curved, pointed, prominent processes at the extremity, 
one or two of which are enveloped in delicate membrane, and are of a red-brown colour. 
Neriene errans is not uncommon among grass and on rails in North Wales and in the 
south of Lancashire.

The eyes are seated on black spots. The cephalo-thorax is oval, slightly convex, glossy, 
rather prominent before, where the eyes are situated, and marked with furrows on the sides 
converging towards a large indentation in the medial line; the falces are moderately strong, 
conical, provided with a few teeth on the inner surface, and a longitudinal row of exceedingly 
short, fine spines in front, near the outer side; they are inclined towards the sternum, which 
is broad and heart-shaped; the maxillae are very gibbous near the base, and incline towards 
the lip, which is semicircular and prominent at the apex; the legs are slender, and provided 
with hairs and fine, erect spines. These parts are of a brown hue; the legs, which are the 
palest, and the falces, maxillae, and lip, which are the darkest, have a tinge of red. The 
anterior and posterior pairs of legs are equal in length; each tarsus is terminated by three 
claws ; the two superior ones are curved and pectinated, and the inferior one is inflected near
