and longer spines situated on the upper side of the thighs, which 

 Clerck in the other species has not observed, but has chanced to 

 see in his Ar. aculeatus: — that any Lycosoid exists, in which these 

 spines really are, as Clerck states, "five or six times longer and 

 thicker" than the other spines of the legs, no one probably will 

 consider as likely. The size of "Ar. aculeatus" forbids our referring 

 that spider to T. meridiana Hahn (L. aculeata Sund.), to which 

 Sundevall reckons it. By C. Koch it is classed under T. andreni- 

 vora (L. inquilina C. Koch). Westrino on the other hand (Aran. 

 Suec, p. 507) considers Ar. aculeatus as a monstrous form either of 

 T. fabrilis or T. inquilina (Clerck). But Clerck's figure bears not 

 the slightest resemblance either to T. andrenivora or T. fabrilis; as 

 for T. inquilina, as Clerck has described it under two other names, 

 Ar. inquilinus and Ar. nivalis, it is hardly credible that he would 

 take it up again under a third appellation; and moreover I cannot 

 see any especial resemblance between T. inquilina and Clerck's fi- 

 gure of Ar. aculeatus. When T. inquilina is excluded, there can 

 hardly be found any other Swedish Lycosoid, than L. taeniata Westr., 

 to which Ar. aculeatus can be referred; and I can discover nothing 

 that militates against the supposition, that Ar. aculeatus is a va- 

 iety of the here in Upland common L. taeniata, in which the upper 

 part of the abdomen is of an almost uniform grey colour, without 

 marking. This variety I in 1868 (loc. cit.) called n Var. /?" of the 

 species. In the commonest variety, or chief form of the species, 

 " Var. a", the abdomen has, as is known, a long, narrow, lancet-formed, 

 pale, longitudinal band, enclosing in the fore part a lancet-formed 

 dark spot: sometimes this spot is rather indistinct, and the longi- 

 tudinal band not so sharply defined, in which cases the chief form 

 passes into the Var. /?; if the band be resolved by transversal, dark, 

 angular marks into a series of spots, of which the first is usually in 

 the form of a large A , and the next- following spot or spots are 

 longitudinally bisected, we have the variety described by Westring 

 under the name of L. cursor, "and which I have called "Var. y " 

 This variety is undoubtedly identical with L. cursor Hahn '). I have 



1) I have received from Simon a spider from France, which he takes to be 

 L. cursor Hahn. It is beyond all comparison smaller than Hahn's species, of 

 which the male is stated to be 5 and the female 6'/ 2 lines long, and which is 

 certainly different from the spider I have received from Simon. As the species 

 appears to be new, it is as well to describe it here. I call it T. Simonis, 

 after the zealous arachnologist who has discovered it, and whom I have to thank 

 for many valuable communications.
