Blackwall's description evidently belongs to the true D. luci- 

 fugus Walck., and seems, as well as the figure, to be chiefly taken 

 from C. Koch's description and figure of this author's Pythonissa lu- 

 cifuga 2 (Conf. Cambr., loc. cit.); at least the description has not 

 been made from English specimens. The female found by Cambridge 

 at Blandford in Dorsetshire, which Blackwall mentions and refers to 

 D. lucifugus, and on which Blackwall's figure is in part founded, 

 is a totally different though closely allied species, which Cambridge 

 has loc. cit. described under the name of D. anglicus, and of which 

 he has kindly favoured me with a cf and 2 ad. In colour this 

 Gnaphosa anglica resembles G. muscorum (L. Koch), concerning which 

 see above, p. 190; the cephalothorax, which is surrounded by a fine 

 border, not by a hem ("Umschlag" : L. Koch), and the legs are red- 

 dish or yellowish brown; the cephalothorax has a fine black lateral 

 border (at least in the male), and a darker v on the pars cepha- 

 lica, behind; the abdomen is greyish or blackish brown. The di- 

 stance of the anterior lateral eyes from the edge of the clypeus is 

 about one and a half times, not double, the diameter of those eyes, 

 which are not much larger than the anterior centre eyes. There is no 

 spine under the tibiae of the fore-legs hereby the species is immedi- 

 ately distinguished from G. muscorum, G. lucifuga and G. montana 

 L. Koch (as regards this last, vid. sup., p. 188 et seq.). In the fe- 

 male that I have seen, the cephalothorax is 3'/ 4 , the list pair of 

 legs 7, and the 4:th 8 '/ 2 millim. , the patella + tibia of the 4:th pair 

 2'/ 2 millim.; in the cf the patella + tibia of this pair are as long as 

 the cephalothorax. The male's bulbus is destitute of the S-shaped 

 hook at the extremity of the bulbus, which distinguishes G. mu- 

 scorum cf ; the tibial joint's outer side is drawn out into a strong, 

 straight, pointed spur, directed forwards and as long as the joint 

 itself. The vulva is a very large area with almost parallel sides,
