Under the denomination of Aran, palustris, Linn^us has in his 

 later works confounded at least two different species of spiders. In 

 the 2 nd Ed. of his Fauna Suecica (1761) p. 491 he cites, under *Ar. 

 pahmtris;", from his previous works two descriptions, which evidently 

 belong to two totally different animals. The one is that taken up 

 1742 in his "Animalia per Sueciam observata", under n:o 9: Ara- 

 nea nigra, pectore abdomineque linea alba cinctis' 1 ), which is prob- 

 ably identical with Dolomedes fimbriatim (Cleeck); the other is the 

 spider described in Fauna Suec, Ed. 1, p. 352 under n:o 1219: Ara- 

 nea nigra, thorace triplici linea longitudinali alba, abdomine nebuloso, 

 which is without doubt identical with L. tar salts; for it is evident 

 from Linnaeus' statement: "habitat in paludibus exsiccatis frequens 

 apud nos", which does not suit L. monticola (Cleeck), that it cannot 

 refer to this last mentioned species, as I in Rec cit. Aran. (p. 51, 

 92) erroneously had supposed. In the Syst. Nat., Ed. 10 (1758) — 

 the work in which Linnaeus for the first time applies "nomina trivi- 

 alia" or specific names to Spiders and to the Animal Kingdom in ge- 

 neral — nothing more appears about "Ar. palustris" than the diag- 

 nosis: "Ar. abdomine oblongo nebuloso: lineis lateralibus albis", aud 

 the statement: "habitat in paludibus exsiccatis csespitosis," together 

 with the citation: "Faun. Suec. 1219", i. e. Lyc. tarsalis, Linn^us 

 does not here cite his Anim. per Suec. observ. ("Act. Ups.") n:o 9, and 

 he has accordingly not definitively expressed the opinion, that this 

 latter species was the same as that described in the Fauna Suec, 

 although the words of the diagnosis seem to indicate that he in- 

 clined to that erroneous opinion. It was in the 2 ttd Edit, of Fauna 

 Suec, 1761 (where the diagnosis is the same as in Syst. Nat., Ed. 

 10) that he for the first time, as has been already mentioned, took 

 the two species before us to be synonymous ; but that it is the spider 

 described in Fauna Suec, Ed. 1: "Ar. nigra, thorace triplici linea 

 longitudinali alba" , or Lyc. tarsalis, that he means, is evident from 

 the description repeated from Ed. 1., where we find: "Neque Fei- 

 schius loc. cit. 4 ), neque Listeeus de Araneis Lupis globiferis, p. 77,
