audax C. Koch, it appears to me that there is no sufficient reasonfor applying the very uncertain trivial name audax (derived fromSchranck) either to any of the species ( Thom, luctuosus Blackw. , Th.calcaratus Westr. £?), which are included under Westring’s Th.audax, or to Th. audax Blackw., which is certainly the same asThom, pini Hahn. Westring has described females of this spe-cies under the name of "Thom, cinereus (C. Koch)”. The male of thesame species he has united with the male of X . cristatus under hisThom, cristatus cT. X . cinereus C. Koch is however a very uncer-tain species, about which there is much difference of opinion: byBlackwall it is aggregated to an entirely different, to me unknownspider {Thom, cinereus Blackw.), and it is not either considered byL. Koch to be identical with Westring’s Th. cinereus (vid. sup., p.237, note). Accordingly there seems to me every reason to designatethis last species by the specific name pini Hahn, which is older thancinereus, and, as far as I am aware, has never been used for anyother species than that in question. — X. mordax C. Koch is, ac-cording to C. Koch himself, identical with Th. pini Hahn; it is onlythrough a slip of the pen that that synonym was adduced by meunder ”X cristatus Var. a". As regards X . viaticus C. Koch (X Kochii Thor.), which Blackwall, Westring and others erroneouslyrefer to X cristatus, vid. sup., p. 236, 241.

The spider which Cambridge ') has described and figured under thename of lit. 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 tobe able to state farther on, in the "Additions". — On Th. Cambridgiisee also above, p. 243.
