The cephalo-thorax is oval, convex, and glossy ; it is prominent before, where the eyes are 
seated, and, with the falces, maxillae, lip and sternum, is of a brownish-black colour. The legs 
have a red-brown hue; the two superior tarsal claws are curved and pectinated, and the 
inferior one is inflected near its base. The palpi resemble the legs in colour; the cubital and 
radial joints are short, and the latter, which is the stronger, has two small apophyses at its 
extremity, one situated in front, and the other on the outer side; the digital joint is somewhat 
oval, with a bold, conical protuberance in the middle ; it is convex and hairy externally, 
concave within, comprising the palpal organs, which are highly developed, complicated in 
structui’e, with a short, curved spine at their base, on the outer side, a long filiform one under¬ 
neath, which curves downwards to their extremity, where there is a pointed spine curved 
outwards, and are of a red-brown colour. The abdomen is oviform, convex above, and 
projects over the base of the cephalo-thorax; it is thinly clothed with hairs, glossy, and of a 
brownish-black hue. 
Several males of this species, having the palpal organs fully developed, were obtained on 
iron rails at Crumpsall Hall in April, 1834, and on plants growing in woods at Oakland, in 
June, 1835.

The cephalo-thorax is oval, convex, glossy, with a minute indentation in the medial line; 
and the falces are inclined towards the sternum, which is broad and heart-shaped. These 
parts, with the maxillae and lip, have a dark, brownish-black hue. The legs and palpi are 
provided with hairs, and are of a dull-yellow colour, faintly tinged with red. 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 abdomen is oviform, convex above, projecting over the 
base of the cephalo-thorax ; it is sparingly clothed with hairs, glossy, and of a black hue. 
The male has an obtuse prominence on the anterior part of the cephalo-thorax, on each 
side of which there is a large indentation, directed backwards from the lateral eyes. The 
radial joint of the palpi is longer than the cubital and tapers to the extremity, which is greatly 
curved outwards, in front of the digital joint; this latter joint is oval, convex and hairy 
externally, concave within, comprising the palpal organs, which are highly developed, com¬ 
plicated in structure, with a slightly curved spine projecting in front from within the curvature 
of the radial joint, and another, almost describing a circle, situated at their extremity; they 
are of a red-brown colour.
