2 ON NEW AND KAR15 BiUTISH SPIDERS. 



Neriene decora. Cambr., and Lrepanodun obzcurus, Mcngo, are now 

 also recorded for the first time as British, though whether 

 the latter is really distinct from Neriene albipunctata, 

 Cambr., is at present somewhat doubtful. In the list 

 which follows will also bo found a record of the occurrence, for 

 the most part in my own immediate neighbourhood, of various 

 other rare, little known, or remarkable spiders, and it is with 

 reference to two of these, Neriene atra t Bl., and Neriene errans, 

 Bl., that I have ventured to make some remarks on the forma- 

 tion, or more properly the evolution, of new species (vide postea, 

 p. 4. and p. 9.). 



OEDEE AEANEIDEA. 



FAM. DRASSID^E. 

 GENUS, PROSTHESIMA, L. Koch. 



PROSTHESIMA PEDESTRIS, C. L. Koch (Cambr. Spid. Dorset, 

 p. 15.) 



On the 13th of June, 1883, I found an adult male of this dis- 

 tinctly coloured species on the pathway between Berewood and 

 Woodbury Hill. This is its first occurrence in this district. 



PROSTIIESIMA LATREILLII, C.L.Koch (Cambr. Spid. Dors. p. 421). 



An adult male of this rare species occurred under an old piece 

 of turf on Bloxworth Heath on the 2nd June, 1884. 



GENUS, DRASSUS Walck. 



DRASSUS SILVESTRIS, BL, (Cambr. Spid. Dors. p. 460). 

 nuswtus, Westr., (Ccmbr. Spid. Dors., p. 423). 



Among some spiders received from Mr. BlackwalFs collec- 

 tion, since his decease, is the typo-specimen of Drassus silves- 

 tris, which on comparison proves beyond a doubt its identity with 

 D. infuscatus, Westr. This latter name therefore becomes a 

 synonym.
