The species here described by Westring, which is commonly 

 met with over the whole Scandinavian peninsula, from Skane to 

 Lappland and the Finnmark, and to which the specific name crista- 

 tus ought unconditionally to be reserved (Conf. Eec. crit. Aran., p. 

 74), has both by Westring and myself been considered identical 

 with that, which from C. Koch has received the name of Xyst. via- 

 ticus. I have however gradually come to the conclusion, that this 

 is a mistake: in 1858 I met at Travemiinde with a to me then 

 unknown male Xysticus, to which C. Koch's description of X.viaticus 

 answers at least as well as to our Swedish X. cristatus; and I have 

 moreover since received both from Ohlert and from L. Koch the true 

 X. cristatus (Clerck) under the name of X. audax C. Koch. Among 

 the specimens of "X audax" sent me by L. Koch, are adult speci- 

 mens of both our Var. a and of X cristatus. L. Koch has also 

 kindly sent me specimens of "X viaticus" which is really identical
