duced in a curviangular form on the inner extremity ; and at the 

 middle of the fore extremity is a small corneous-looking prominent 

 point or tooth. The digital joint is short, oval, and small ; the 

 palpal organs are well developed, but not very complex. The form 

 of the palpi distinguishes this Spicier readily from N. excisa. 



The colour of the palpi is the same as that of the legs. 



The abdomen is oval, and projects a good deal over the base of 

 the cephalothorax ; it is of a sooty yellow-brown colour, marked with 

 some transverse curved lines on the hinder part of the upperside 

 (which are probably only visible in spirit of wine) . 



An adult male of this very distinct species was received from Dr. 

 L. Koch, by whom it was found at Nuremberg. 



Erigone (Neriene, Bl.) digitata, sp.n. (PlateLXVI. fig. 14.) 



Male adult, length ^ of an inch. 



The whole of this Spider, except the legs and palpi, which are 

 dull greenish yellow, is of a dull greenish sooty-black colour, the 

 abdomen being darker than the rest and sparingly furnished with hairs. 



The cephalothorax is elevated in front, the upper part of the 

 caput being rounded, with a deep and conspicuous longitudinal in- 

 dentation on either side a little below the summit ; the caput is 

 furnished with a few short bristly hairs ; and the clypeus and eye 

 area are bluff and rounded. The eyes are placed on the fore part 

 of the caput, in a somewhat oval group, considerably below the 

 summit, and a little below the midway point of the facial space : 

 the height of the clypeus appeared to be slightly greater than half 

 the facial space, and slightly less than the space from the hind 

 central eyes to the summit of the caput ; the hind central eyes are 

 about level with the lateral indentations, and are separated from each 

 other by about the length of an eye's diameter ; and about the same 

 distance below them is the fore central pair, the eyes of which are a 

 little smaller and close together; those of the lateral pairs are 

 placed obliquely, the hinder one of each being further from the hind 

 central on its side than the hind centrals are from each other. 



The legs are slender, and their relative length is 4, 1, 2, 3, those 

 of the fourth pair being perceptibly the longest. 



The palpi are rather suffused with a greenish sooty hue ; the 

 radial joint is stronger than the cubital, enlarged at its extremity, 

 which is produced in front, towards the inner side, into a pointed 

 finger-like apophysis ; and towards the outer side is a much shorter 

 but stronger apophysis, the extremity of which is squared off. These 

 projections, and the adjacent portion of the joint, are of a reddish 

 colour ; the digital joint is small ; the palpal organs are well de- 

 veloped and complex, with a small spiral black spine beneath their 

 extremity. 



The falces are rather long, but not very strong, sloping towards 

 the extremity on the inner side (where there are a few fine sharp 

 teeth), perpendicular, a little divergent when looked at from the front, 

 and about equal in length to the height of the facial space. 



A single example of this Spider was forwarded to me for exami-
