superior tarsal claws are curved and pectinated, and the inferior one is inflected near its base. 
The palpi resemble the legs in colour, and have a curved, pectinated claw at their extremity. 
The abdomen is oviform, thinly clothed with short hairs, convex above, projecting over the 
base of the cephalo-thorax; the upper part is of an olive hue, irregularly bordered with black; 
in the middle of the anterior part there is a white, longitudinal streak, which is succeeded by 
a fine black line, having on each side a few short, oblique white streaks ; a broad, yellowish 
band, which is palest at its superior margin, and is sometimes tinged with red below, extends 
along each side, and a faint yellow streak occurs on each side of the medial line of the under 
part; the colour of the branchial opercula is dull, yellowish-brown. 
The male is smaller than the female, and its abdomen, which is darker coloured, is more 
distinctly marked. The fangs of its falces have a slight indentation near the middle, exter¬ 
nally, and a corresponding projection within the curve. The radial joint of the palpi is longer 
than the cubital, and clavate ; the digital joint consists of two parts ; the shorter and slenderer 
part is connected with the upper side of the palpal organs, and the longer is in contact with 
the same organs on the inner side, and extends a little beyond them; the palpal organs are 
glossy and globular at the base, with a pointed process anteriorly, which has the appearance 
of being twisted, and are of a very dark, reddish-brown colour, approaching to black. 
In autumn, adult males and females of this species may frequently be seen running on 
the ground in various parts of Lancashire, Denbighshire, and Cambridgeshire. A collection 
of spiders received from Charles C. Babington, Esq., M.A., in 1840, and another made in 
Northamptonshire by the Rev. Hamlet Clark, in 1842, contained specimens of Pachygnatha 
Degeerii; it is also found in Scotland, Mr. J. Hardy having taken both sexes in Berwickshire, 
in the spring of 1849, and Mr. R. Templeton has captured it in Ireland.
