SIMON also takes up Plexippus among the European Attoidæ, and 
gives as the chief features that distinguish it from nearly related genera 
the following characteristics of c: "patte machoire (the palpus) gréle, très 
longue, à tarse moins large que la jambe" ?. He assigns to it only one 
European species, P. Adansonü Sav. et AUD. I do not know to which ge- 
nus this to me unknown spider ought properly to be aggregated: SIMON 
indeed calls his Plexippus: ” Pleaippus C. KOCH ex parte"; but he also says 
of it: "Tel que nous le concevons ce genre n'a aucun rapport avec celui 
de M. Kocx” ?, and I therefore do not venture to take up Plexippus KocH 
among the European genera.
