a for ward -directed, somewhat appressed spine, the extremity of which 

 is pretty abruptly bent inwards and somewhat backwards (towards 

 the former spine). The lamina has on its outer edge a dark, knob- 

 like process. The inferior process of the pars tibialis is broad, di- 

 lated towards the end, and curved somewhat forward; its anterior 

 corner forms an acute, the posterior an obtuse angle: the obliquely 

 truncated extremity is slightly emarginated. The cephalothorax is 

 more convex, arched longitudinally. Its general colour is brownish 

 or rusty red, not dark brown, as in cf of X. cristatus. The palpi, 

 even the lamina, are of a pale colour, brownish or greyish yellow. 

 The 4 anterior femora are usually but little darker than the following 

 joints, but sometimes dark brown, as in C.Koch's figure. The upper 

 side of the abdomen is of a fine reddish , sometimes blackish , brown : 

 the greyish white dorsal band is narrow, but usually very clear, 

 with its lateral teeth long, narrow, and extending almost to the 

 greyish white limbus surrounding the upper side of the abdomen. 

 The female, which strongly resembles X. cristatus 9, but is covered 

 with stronger and thicker bristles, especially on the abdomen, is 

 distinguished by the vulva being composed of two tolerably large, 

 obliquely placed, oval, low tubercles converging backwards, ordinarily 

 of a brown or blackish colour, and each bordered internally by a 

 depressed curved line, so that the interval is almost )(-formed. The 

 abdomen's pale, indented dorsal band is something narrower than in 

 X. cristatus 9 , its teeth longer och sharper, extended transversely; 

 the first pair of these teeth are usually broader, and form two iso- 

 sceles triangles, projecting at right angles from the band, the three 

 remaining pairs are narrower, directed outwards and somewhat back- 

 wards; the anterior portion of the sides of the abdomen is often rosy 

 red, and the same colour may sometimes be seen on the sternum. So 

 also in Thorn, lateralis Hahn, according to Hahn's description and figu- 

 res '); and as I am fully convinced that 77*. lateralis Hahn is iden- 

 tical with the spider of which we are now speaking, I propose to 

 call it Xysticus lateralis (Hahn) 1831. The figure given by Hahn in 

 Monogr. Aran, is better than that in Die Arachn. 



X. lateralis (Hahn) nob., or X lanio C. et L. Koch, is met with 

 also in Scandinavia: I have one male specimen, which I many years 

 ago captured at Goteborg, and another which I took at Stockholm; 

 the species has also been found in Skane and Blekinge by Mr Eisen, 

 and in Smaland by Dr. v. Porath.
