audax C. Koch, it appears to me that there is no sufficient reason 

 for applying the very uncertain trivial name audax (derived from 

 Schranck) either to any of the species ( Thorn, luctuosus Blackw. , 77*. 

 calcaratus Westr. % ?) , which are included under Westring's Th. 

 audax, or to 77*. audax Blackw., which is certainly the same as 

 Thom. pint Hahn. Westring has described females of this spe- 

 cies under the name of *I%om. cinereus (C. Koch)". The male of the 

 same species he has united with the male of X cristatus under his 

 Thom. cristatus d*. X cinereus C. Koch is however a very uncer- 

 tain species, about which there is much difference of opinion: by 

 Blackwall it is aggregated to an entirely different, to me unknown 

 spider {Thom. cinereus Blackw.), and it is not either considered by 

 L. Koch to be identical with Westring's Th. cinereus (vid. sup., p. 

 237, note). Accordingly there seems to me every reason to designate 

 this last species by the specific name pint Hahn, which is older than 

 cinereus, and, as far as I am aware, has never been used for any 

 other species than that in question. — X mordax C. Koch is, ac- 

 cording to C. Koch himself, identical with Th. pini Hahn; it is only 

 through a slip of the pen that that synonym was adduced by me 

 under "X cristatus Var. a". As regards X. viaticus C. Koch (X 

 Kochii Thor.), which Blackwall, Westring and others erroneously 

 refer to X cristatus, vid. sup., p. 236, 241.

The spider which Cambridge ') has described and figured under the 

 name of Th. Cambridgii cT, is identical with Xyst. impavidus Thor. 

 (see above, p. 230), and is therefore the male to Th. lanio Westr.; 

 whether it also is the male to Th. Cambridgii Blackw., I hope to 

 be able to state farther on, in the "Additions". — On Th. Cambridgii 

 see also above, p. 243.
