perpendicularly or with a slight backward direction, whereas 

 in E. spinosa, this spur is strongly directed forward, and has 

 a perceptible curve in its anterior portion. Of course there are 

 other specific differences also from the known species, but those 

 mentioned are sufficient for the present notice. The female 

 does not offer the distinctions named in respect to the other 

 sex, excepting in a slight degree, but the female may be

separated from that of other species without difficulty by the 

 usual sexual test. It will be gathered, no doubt, from what has 

 been observed above, that E. spinosa is one of our minute 

 spiders but not by any means the smallest, nor anything like 

 it. The length of the male is a little over one line, while the 

 female is slightly longer. There is, however, some variation 

 in the size of different individuals of other species of Erigone, 

 arid there is the same also in the foreign examples of this species. 

 It can hardly be doubted but that a little careful collecting in 

 the locality where the examples recorded now were found, 

 would turn it up again and very possibly in fair abundance.
