refers it erroneously to G. lucifuga. — I see no reason to doubt that 

 Fil. femoralis is identical with the species here described by We- 

 string; and that this again is the same as Pyth. tricolor L. Koch, I 

 collect from L. Koch's accurate description and from specimens in my 

 cabinet, which he has himself identified as belonging to P. tricolor, 

 under which name I have also received specimens of Westring's 

 Pyth. femoralis from Dr Ohlert. 



Drassus bicolor Hahn is referred by L. Koch (loc. cit., p. 151) 

 to Melanophora electa C. Koch (Die Arachn., VI, p. 83, Taf. CC, 

 fig. 490), which he therefore calls Mel. bicolor; but this cannot be 

 right, partly because according to Hahn D. bicolor is 3 lines long 

 (which is also the length C. Koch gives for his Pythonissa bicolor), 

 whereas Mel. electa is a much smaller spider (according to C. Koch 

 it is but l 3 / 4 lines long), partly because it is evident from the po- 

 sition of the eyes in Hahn's figure, that his D. bicolor is no Melano- 

 phora, but a Pythonissa or Gnaphosa. C. Koch also, who first (Uebers. 

 d. Arachn. -Syst., 1, p. 17) referred D. bicolor Hahn to Melano- 

 phora, has subsequently (ibid., 5, p. 28) taken it up as a spe- 

 cies of his genus Pythonissa. I therefore adopt the view of those 

 authors, Walckenaer, Westring etc., who consider Drassus bicolor 

 Hahn as synonymous with Pythonissa tricolor C. Koch or femoralis 

 (Keuss), Westr. — In one of my specimens the anterior metatarsi 

 have on the under side not only two spines nearer the base, but 

 also one at the extremity. The cephalothorax appears to me to be 

 bounded at its edge rather by a narrow hem ( Umschlag" L. Koch) 

 than a fine border ("Kante"), at least it exhibits that appearance in 

 some specimens preserved in spirits. — G. bicolor is one of the spe- 

 cies, which Sundevall loc. cit. has put together as varieties of Me- 

 lanophora nocturna (Linn.). 



Drassus bicolor Costa 1835 (Cenni zoologici, p. 64) is quite a 

 different spider, on which vid. infra sub Melanophora nocturna Westr.

It appears to me very probable that this spider of Westring's 

 is the same as C. Koch's Pyth. fumosa, and I therefore preserve 

 that specific name. Westring has kindly lent me his (unfortunately
