Length of the female, Ath of an inch; length of the cephalo-thorax, ~th, breadth, s ' B th ; 
breadth of the abdomen, ^th; length of an anterior leg, jth; length of a leg of the third 
pair, reth. 
The legs have a bright-rufous tint; they are provided with hairs and fine spines, and the 
anterior and posterior pairs are equal in length; 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 cephalo-thorax is oval, convex, 
glossy, somewhat depressed on the sides, and has a small indentation in the medial line. The 
falces are strong, conical, armed with teeth on the inner surface, and slightly inclined 
towards the sternum, which is heart-shaped. The maxillae are enlarged at the extremity, and 
inclined towards the lip, which is semicircular and prominent at the apex. The cephalo- 
thorax, sternum, and lip, have a brown colour, that of the falces and maxillae beino' dark, 
reddish-brown. The abdomen is oviform, projecting a little over the base of the cephalo- 
thorax ; it is sparingly clothed with hairs, glossy, and of a brownish-black hue; and the colour 
of the branchial opercula is brown. 
The sexes are similar in colour, but the male may easily be distinguished from the female 
by its palpi. The cubital and radial joints are short, the latter, which is much the stronger, 
being prominent in front; the digital joint is oval, convex and hairy externally, concave 
within, comprising the palpal organs, which are highly developed, complicated in structure, 
and of a dark, reddish-brown colour. 
Neriene pygmcea is plentiful among the grass of old pastures in Lancashire and North 
Wales, and may frequently be seen running on rails and on footpaths.
