n. 25, 26, 27, 28, in ulla specie meminit thoracem utrinque linea 

 alba longitudinali notari, nec tertiam album lineam longitudinalem 

 thoracis a medio dorsi. Hinc de synonymis hsereo. Thorax in aliis 

 niger. [This expression seems to indicate, that Linn-eus here con- 

 founded some other species with the real Ar. palustris.'] Abdomen 

 nigrum, maculis nigerrimis quasi nebulosum." — In the 12 th Edition 

 of Systema Naturae, I, P. ri, p. 1036 (1767), he has again excluded 

 the citation from "Act. Ups." (JJol. fimbriatusf): here we have the same 

 statement about Ar. palustris as in the 10 th Ed., with however the 

 addition: "Afinis A. saccatcp" and a citation from the 2 nd instead of 

 the 1 st Ed. of Fauna Suec. — As Linn^ius then in his Syst. Nat., 

 Ed. 10, where the name Ar. palustris first occurs, and from which 

 the priority ought to be reckoned, understood evidently, as may be 

 seen from his citation, by that name Lyc. tarsalis (even though he 

 may have confounded some other, it cannot be determined which, 

 species with it), and only some time afterwards united Dolom. fim- 

 briatus (?) with this spider, I conceive that we cannot do otherwise 

 than accept the Linnean specific name palustris for Lyc. tarsalis. — 

 C. Koch cites Ar. palustris Linn, under his Potamia piratica (Die 

 Arachn., XV, p. 1), which appears to me quite gratuitous. Ar. 

 palustris Fabb. on the other hand does, as C. Koch assumes, belong 

 to his P. piratica. 



Aran, palustris Mull. (Faun. Ins. Fridrichsd., p. 94), and Ar. 

 palustris Schranck (Fauna Boica, III, i, p. 235), under which not 

 only Ar. palustris Linn, and Ar. saccata Olafs. '), but also Ar. Listeri 

 Scop. 2 ), which appears to be a 2arentrda, and Geoffroy's "Araignee 

 porte-feuille" are quoted, certainly do not belong to this species, 

 but ought probably rather to be referred to Dolom. fimbriatus (Clerck). 



Ar. dorsalis Fabr., which Schrank cites under his Ar. dorsalis 

 and C. Koch under his Lyc. monticola, probably does not belong to 

 this species, but to Lyc. lugubris Walck. Vid. sup., p. 277, under 

 L. silvicola Westr. On the other hand I am, like C. Koch, fully 



probable that it may have been a Tarantula or Trochosa (Tr. terricola Thor. ?), 

 judging from the alleged size and from the position of the eyes, as also because 

 the cocoon is stated to be "spherical, white." Linnjeus mentions this spider not only 

 under his Ar. palustris, but also under his Ar. saccata.

 ductis notata. Faun. Suec. 1219, Knoda-Kongulo, on the grass-fields" (Reise 

 igienn. Isl., I, p. 609), is probably = Lyc. palustris (Linn.), NOB.
