 two distinct species, Th. cristatus Blackw. and Th. pini Hahn or 

 Th. audax Blackw. are confounded: to the former the synonyms be- 

 long, which are taken up under 'Var. a (Forma principalis) ', with 

 exception of Xysticus morclax C. Koch, and X. audax id. ad part. 

 (loc. cit., figg. 1007, 1008), which, together with the synonyms given 

 under 'Var. /?, pini', belong to Th. pini Hahn: vid. sup., p. 424.

 brevipes (Hahn) 1831", read: = Xysticus Westringii N. + JCysticus pra- 

 ticola C. Koch 1837. 



L. Koch, as I find from specimens with which he has favoured 

 me, considers Xyst. praticola C. Koch as identical with Thorn, incer- 

 tus Blackw.; and although this species and TJwm. brevipes Westr., 

 to which I have p. 254 referred X. praticola C. Koch, are so similar 

 to each other, that they have probably not been distinguished by C. 

 Koch, I nevertheless, after a renewed study of C. Koch's descrip- 

 tions and figures, think, that Th. incertus Blackw. is the species, 

 which ought to bear Koch's specific name praticola: it appears for 

 example from C. Koch's figure of the male, that the thighs of the 

 2:nd pair have tivo spines, which is not the case in Th. brevipes
