developed and complex, but its spiny processes present no 

 especially remarkable feature. 



Found on iron railings, running in sunshine, and also among 

 moss in woods in spring time, at Bloxworth. It has also occurred 

 in some abundance in North Wales, in the month of December. 



WALCKENAERA LATIFRONS. 



Walokenaera latifrons, Cambr., Zoologist 1860, p. 8694. 

 Adult male length l-14th of an inch. 



The caput is distinctly and roundly elevated ; the elevation, 

 however, is not excessive, its perpendicular height not exceeding 

 l-3rd of the whole height of the caput at that part. The upper 

 fore extremity of the caput is considerably prominent, axid forms 

 an anterior lobe or segment, divided from the posterior by a 

 strong transverse cleft or indentation. The eyes of the hind- 

 central pair are wide apart, in a transverse line, near the fore 

 part of the summit of the posterior segment ; the other three 

 pairs are placed in a transverse line near the extremity of the 

 anterior segment, and behind each lateral pair of eyes is a deep 

 longitudinal indentation. Each segment has some hairs upon it ; 

 those on the hinder one are short, bristly, and erect, those on the 

 fore one form a sort of tuft directed backwards over the dividing 

 cleft. 



The colour of the cephalo-thorax is deep blackish-brown, that 

 of the legs is a paler and brighter brown, and the abdomen 

 deep sooty black. The cubital joint of the male palpus is larger 

 than the radial, and enlarges gradually to its extremity. The 

 radial joint is strong, and has its fore extremity on the upper 

 side largely and broadly produced over the digital joint. The 

 produced part has an outward direction, and at its extreme out- 

 ward part is a long, slightly curved, pointed process directed 

 across to the inner side. The palpal organs are prominent and 

 complex, with several curved, corneous, and spiny processes at 

 their extremity.
