440 Rev. O. P. Cambridge on new Species of Spiders. 



Abdomen oval, sparingly clothed with hairs, pale murky 

 shining ochre-coloured ; in many individuals of both sexes 

 strongly tinged with brown. 



The female resembles the male in colour, but is larger, and 

 wants the frontal eminence, the front of the cephalothorax being 

 merely slightly elevated, with a longitudinal indentation in the 

 medial line. 



Both sexes of this very remarkable-looking spider (both ma- 

 ture and immature) were discovered by myself in abundance on 

 furze-bushes at Hursley, near Winchester, Lyndhurst, and at 

 Bloxworth, Dorset, at the end of May 1860. 



Walckenaera saxicola. 

 Cephalothorax dark brown; abdomen brownish black; legs pale 

 yellowish brown, with the tibia of the first and second pairs 

 dark brown ; frontal eminence moderate, and behind it a slight 

 transverse dip or compression : palpi short ; radial joint shorter, 

 but larger and stronger than the cubital, and with several pro- 

 jections ; digital joint large ; palpal organs highly developed 

 and complex. 



Adult male. — Length j^ of an inch ; relative length of legs 

 4, 1, 2, 3. 



Cephalothorax prominent in the region of the eyes, rounded 

 and very convex, compressed on the sides, and with a slight 

 transverse dip behind the frontal prominence; behind this dip 

 there is an indentation in the medial line. Colour dark brown. 



Eyes eight, on front and top of cephalothorax in four pairs, 

 forming two transverse rows curved from each other, the front 

 row far more strongly curved than the hinder one ; the eyes of 

 the middle pair of the front row are much closer together than 

 the middle ones of the hinder row, and the smallest of the eight, 

 the central ones of the hinder row being the largest ; those of 

 the side j)airs are on a small tubercle, and touch each other. 



Legs moderately long, not very slender, furnished with hairs; 

 their relative length is 4, 1, 2, 3. Each tarsus ends with three 

 claws. Colour pale yellowish brown, with the tibia of the first 

 and second pairs dark brown. 



Palpi short : radial joint about the same length as the cubital, 

 but much thicker and stronger ; it has three projections at its 

 extremity — a long, slender, deep-brown one curved outwards in 

 front of the digital joint, a strong crescent-shaped one in front 

 towards the outer side, and a short obtuse one underneath ; the 

 two latter are not so dark-coloured as the first : digital joint large, 

 somewhat oval, convex and hairy outside : palpal organs highly 

 developed, complicated, and with a black filiform spine near the
