(Spid. of Gr. Brit., II, p. 2C>6) or Dicymbiwn clavipes Menge (Preuss. 

 Spinn., II, p. 193, PI. 37, tab. 91), I have found a cf ad. near 

 Stockholm. It had not previously been met with in Sweden. 



(Pag. 208.) 7. E. bicuspidata [= Erigone cornuta (Blackw.) 1833]. 



Syn.: 1833. Neriene cornuta Blackw., Charact. of some undescr. gen. and 



spec, etc., in Lond. and Edinb. Phil. Mag., 3 

 Ser., in, p. 190. 

 1851. Erigone bicuspidata Westr., Forteckn. etc., p. 41. 

 1864. Neriene cornuta Blackw., Spid. of Gr. Brit., II, p. 267, PI. 



XVin, fig. 181. 



1869. DlCYPHUS CILUNCULUS Menge, Preuss. Spinn., Ill, p. 222, PI. 44, 



tab. 122. 



Mieryphantes bicuspidatus C. Koch (Die Arachn. , IV, p. 138, 

 Taf. CXLIV, figg. 338, 339), which is stated to have on its head 

 two hornlike projections, each carrying one of the posterior central 

 eyes (?), and which Westring, with a note of interrogation however, 

 quotes under this species, cannot with any certainty be referred 

 to it. Menge refers it, though also with an interrogation, to quite 

 a different species, Dicyphus bicuspidatus Menge (Preuss. Spinn., 

 Ill, p. 223, PI. 44, tab. 123), which appears to differ from E. bi- 

 cuspidata Westr. or Neriene cornuta Blackw. principally by the head 

 of the cf not presenting, when viewed from before, any strongly 

 marked ledge on both sides beneath the tubercles, by the central 

 eyes not being situated on a sloping protuberance, but immediately on 

 the vertical forehead, and by the absence, on the tibial joint of the 

 palpus, of the long apophysis at the apex, on the inner side, which 

 marks Westring's E. bicuspidata. At any rate Blackwall's specific 

 name has the priority for the spider here described by Westring, 

 and which is identical with Menge's Dicyphus cilunculus, of which 

 Menge lent me specimens to compare. 



Ohlert's description of Mieryphantes bicuspidatus (Aran. d. 

 Prov. Preuss., p. 57) seems to be only an extract from C. Koch's. 



English specimens of Blackwall's Neriene coi-mda have been 

 kindly given to me by Mr. Cambridge. — Theridium comutum 

 Keuss or Erigone cornuta Westr. is quite a different species. Vid. 

 inf. p. 109.
