348 On some new Species of Araneidea. 



base of the cephalo thorax, and is jet-black, thinly clothed with 

 hairs. 



A single example, in excellent condition, of this very 

 remarkable little spicier was kindly sent to me, from Lisbon, 

 with numerous other spiders, by Mr. H. 0. Forbes. 



Walckenaera congenera, sp. n. (PI. XVII. fig. 5.) 



Adult male, length 1 line. 



The cephalothoraw is of a deep rich black-brown colour, the 

 legs orange, and the abdomen jet-black. The caput is elevated 

 into a moderate-sized, well-rounded eminence ; the height of 

 the clypeus is a little over half that of the facial space ; it 

 slopes forwards following the same line as that of the fore 

 profile of the eminence on the caput. The upper (or hind- 

 central) pair of eyes are seated on the fore part of the upper- 

 side of the eminence, and are separated by an eye's diameter. 



The legs are slender, of moderate length, 1, 4, 2, 3, and 

 furnished with hairs only ; if any other armature was ever 

 present it had been rubbed off before the example came to 

 hand. 



The palpi are moderately long, slender, and of a yellow colour, 

 excepting the digital joint, which is dark yellow-brown. The 

 cubital joint is slightly clavate and bent downwards ; the radial 

 joint is stronger than the cubital, and has its fore extremity, on 

 the upperside, produced into a long, somewhat tapering, and 

 curved apophysis, whose broadly obtuse point is directed out- 

 wards across the middle of the digital joint, and a little turned 

 upwards on the lower edge ; within the curvature of this 

 apophysis is a strong, not very long, obtuse, prominent process 

 also directed outwards ; and in front of it (though it was 

 difficult to see its exact origin) is a small, sharp-pointed, 

 spine-like projection ; numerous bristly hairs issue from the 

 outer side of the radial joint, chiefly towards its hinder part ; 

 the digital joint is oval and of tolerable size ; the palpal organs 

 are well developed and complex ; they are closely encircled 

 near the middle with a black spine ; and a more slender one 

 coiled in a circular form is situated at their extremity. 



The maxillce are of an olive-brown hue, the labium blackish 

 brown ; the sternum is glossy and black -brown ; and the abdo- 

 men, which is also glossy, is jet-black, rather large, consider- 

 ably convex above, and very sparingly clothed with hairs. 



This spider is closely allied to Walckenaera prcegracilis, 

 Cambr., but is larger ; the legs are also shorter ; the eminence 

 on the caput is of a more rounded form, and less sloping 

 in profile both before and behind ; the two eyes seated on its 

 summit are also nearer together. The p> a h^ ave somewhat
