a strong, truncated process or lobe, pointing outwards and foru'ards, 

 and bearing at its apex a pointed tooth directed down/cards , forming 

 an almost right angle with the process; the bulbus has at the base, 

 immediately before that process, a somewhat longer, upwards- and 

 forwards-curved spur, and at the apex a long, almost circularly cur- 

 ved spine. The clava is irregularly rounded, shorter than the tibia of 

 the 1 st pair. The legs and palpi are of a brownish- or rusty yellow co- 

 lour, the cephalothorax and dorsal shield of the abdomen dark brown. 



Wahlenaera depressa Blackw. 1836 ') is probably a synonym to 

 this species; the description and figures given by Blackwall appear 

 however to me to suit the following species, E brevipes Westk., 

 about equally well; perhaps have both been confounded by Black- 

 wall under the name of W. depressa. 



In a nearly related species, of which L. Koch presented me with 

 specimens collected in the neighbourhood of Niirnberg, and which I 

 call E. Wideri, the legs and palpi, with the exception of the brown 

 bulbus genitalis of the c? , are bright yellow; the male's tibial joint, 

 which is shorter than the patellar joint, is at the order side drawn 

 out into a triangular tooth; the clava is oblong, very large, as long 

 as the tibia of the first pair; the spur at the base of the bulbus is 

 longer and coarser than in E. brevis. The cephalothorax is rather 

 paler than in that species, the head is considerably higher, sloping 

 slightly backwards above, sloping rapidly behind towards the pars 

 thoracica, with a straight, or rather slightly concave, dorsal surface, 

 SO that the posterior centre eyes are situated higher than any other 

 point of the cephalothorax. See also next species.

Of this species, the male of which was unknown to Westring, 

 this author has kindly sent me the type-specimen to examine. It 

 appears to differ from Erigone brevis ? almost only by the head 

 being separated from the thorax by somewhat deeper grooves, and by 

 the cephalothorax having impressed points only on the sides, near 

 the edge, while the rest of its surface is smooth and shining,
