The caput is rather, but not greatly, elevated ; it is strongly 

 compressed and deeply indented on the sides of the elevation ; 

 and its extremity is divided into two segments by a transverse 

 indentation. The hinder segment is blunt pointed and has the 

 hind-lateral pair of eyes near its summit. The anterior segment 

 is large and bluff, in fact representing the ordinary fore part of 

 the caput, and bears the fore-central and two lateral pair of oyes 

 in a transverse line. Each segment is surmounted with a few 

 short fine hairs. The radial joint is produced, at its fore extremity 

 in front, into a strong broad and obtuse apophysis. The digital 

 joint is small, and the palpal organs are not very complex. 



The colour of the cephalo-thorax, legs, and palpi is brown, 

 and that of the abdomen brownish-black. 



Found not unfrequently among moss in May and June under 

 hedges and in woods at Bloxworth. It has also occurred in 

 North Wales and Scotland. 



WALCKENAERA IGNOBILIS. 



Walckenaera ignobilis, Cambr., Trans. Linn. Soc. xxvii., p. 

 457, pi. 57, No. 42. 



The adult male of this very minute spider measures no more 

 than l-20th of an inch in length. 



The caput is slightly and obtusely elevated, chiefly in 

 the occipital region ; on the fore part of this elevation are the 

 eyes of the hind-central pair, and lower down in a transverse 

 curved line are those of the other three pairs. At the middle of 

 the lower margin of the clypeus near the insertion of the f alces 

 is a somewhat pointed sub-tubercular prominence, by which this 

 species may easily be determined ; in the region of the eyes are 

 some short, strong, prominent hairs. Palpi short ; the radial 

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

 upper side, produced into a broad and large apophysis, whose 

 outer edge is rather hollow, and its inner extremity narrowed 

 into a long spiny point curving sharply round with its point 

 directed outwards.
