(Pag. 135.) 26. L. pai'VUla [- Liiiyphia partula Westr. 1851]. 

 Syn.: 1851. LiNYPHU PARVULA Westr., Forteckn. etc., p. 59. 



This spider, though pretty common in Sweden, I have been 

 unable to find among the species described by Blackwall and Menge. 

 According to Cambridge ') it is however met with in England. — 

 The vulva is very small, black, and destitute of any projecting 

 parts. 



(Pag. 137.) 27. L. convexa [= Linyphia convexa Westr. 1851]. 



Syn.: 1851. Erigone convexa Westr., Forteckn. etc,, p. 60. 

 1851. ,, reticulata id., ibid., p. 59. 



The vulva in this little species is much more distinct than in 

 L. parvula, and appears (in a dried specimen) to consist of a pretty 

 deep fovea, limited in front by an almost semicircular border, and 

 exhibits two small reddish brown elevations behind. This species 

 seems not to have been described either by Blackwall or Menge. 



(Pag. 138.) 28. L. gracilis [= Linyphia variegata (Blackw.) 1841].

XIX, fig. 195. 



The Rev. Mr. Cambridge has sent me a cT and $ of the Neriene 

 variegata of Blackwall, which, though tolerably differing from my 

 Swedish specimens of Lin. gracilis Westr. in the colour of the ab- 

 domen, with certainty belong to this species. In a ? of L. gracilis 

 Westr. sent to Mr. Cambridge, he also recognized N. variegata 

 Blackw. The figures (loc. cit.) of A r . variegata show but little simi- 

 litude to L. gracilis Westr., but the description suits tolerably well. — 

 Blackwall had already in 1841 (The differ, in the numb, of eyes, 

 etc., p. 666) appropriated the name gracilis to another species of 

 the genus Linyphia.
