Arachnida. 



which curves over the base of the digital joint towards the outer 

 side, and ends in a fine red-brown point. A small, brownish, 

 semitransparent process issues from the curvature, and projects 

 outwards. Palpal organs complex and prominent, of a red- 

 brown colour. Several black spines issue from them, one of 

 which curves across the middle ; another shorter and stouter, 

 and sharply curved like a reap-hook, issues from their extre- 

 mity. The female is rather larger, but resembles the male in 

 all except the absence of the frontal elevation. 



I met with adult males and females of this very distinct species on 

 underwood at Lyndhurst, in the New Forest, in May, 1860. It is 

 allied to W. fastigata, but in that species the division of the upper 

 and lower segments of the frontal elevation is much more clearly and 

 strongly marked ; it differs much also from the present species both 

 in colour and in the form of the palpi and palpal organs. 



Walckenaera latifrons. 



Male, adult. Length 1-fourteenth of an inch. Length of cephalo- 

 thorax 1 -twenty-eighth. Relative length of legs, 1 — 4, 2, 3. 



Cephalothorax deep blackish brown. Ocular region prominent and 

 elevated, and divided into two segments by a deepish transverse 

 groove ; the front segment rather below, as also less large, bold 

 and obtuse than, the hinder one, which is broad, obtusely 

 rounded, and slightly enlarged laterally at the top : this seg- 

 ment has a deep horizontal indentation on each side at its base, 

 behind each side pair of eyes. A few very short, strong, bristly, 

 blackish, erect hairs are on the top of the hinder segment; and 

 the summit of the front segment has a tuft of paler hairs 

 stretching over the groove that divides it from the hinder one. 



Eyes in four pairs — one pair on the fore part of the summit of the 

 hinder segment ; the eyes of this pair are wide apart, and the 

 largest of the eight : the other three pairs are on the front seg- 

 ment ; each pair wide apart from the other ; one pair is on the 

 black, obtusely-pointed and rather prominent summit of this 

 segment ; the eyes of this pair are smallest of the eight. The 

 side pairs have each the front eye larger than the hinder one. 



Legs not very long; stout and hairy, of a paler and brighter brown 

 than the cephalothorax. 



Falces, maxillae and labium similar in colour to the legs, the 

 labium being rather the darkest.
