a larentula from Ntirnberg, which he considers as the true Lyc. 

 cursor Hahn, and which is quite different from and much smaller 

 than the variety of L. tceniata Westr. or Tar. aculeata (Clerck), n., 

 which I, with Westring, took to be identical with Hahn's L. cursor. 

 In favour of L. Koch's opinion may be adduced, that, according to 

 Hahn's description and figure, "L. cursor" has broad pale lateral 

 bands on the cephalothorax , which is not the case in L. cursor 

 Westr. or T. acxdeata, Var. y, sr.; against this identification might 

 be objected that the size of "L. cursor", according to Hahn, is much 

 greater than that of the species to which L. Koch applies the spe- 

 cific name cursor Hahn. As however the measures given by Hahn 

 are often extremely faulty, I think that no great weight can be laid 

 on this latter circumstance; I now believe that Dr Koch is right in 

 his identification, and that L. cursor Hahn must be effaced from the 

 synonyms of L. tceniata Westr. 



The true T. cursor (Hahn), (L. Koch), is very closely allied to 

 the spider, which 1 have described (p. 326) under the name of T. 

 Simonis: had not the sexual organs presented some slight differen- 

 ces, I should have considered these two forms to be identical. — 

 The female of T. cursor is about 7 ! / 2 millim. long ; its cephalothorax 

 is 3% millim. in length and 2'/ 4 millim. in breadth, the l:st pair 

 of legs is 7'/ 2 , the 4:th 10'/ 2 , the patella + tibia of the 4:th pair 3, 

 the tibia alone 2 millim. The cephalothorax is dark brown with three 

 pale, greyish, longitudinal bands, the middle one very broad, some- 

 what tapering on the hinder slope; the lateral bands are also rather 

 broad, coarsely dentated in the inner margin. The sternum is black- 

 ish brown, glossy; the legs and palpi of a dark yellowish brown, 

 the femora with dark spots, the following joints with more or less 

 distinct dark rings. The abdomen is of a greyish dark-brown co- 

 lour; on the upper part, in front, it exhibits two large, oblong, 

 oblique, orange-yellow spots, together forming a large and coarse 

 a; behind this mark are two much smaller, longitudinal, greyish 

 yellow spots or lines somewhat diverging behind; immediately be- 

 hind these spots, from the middle of the back to the anus, a broad 

 dentated greyish yellow band extends itself, which band by some 

 angularly bent, narrow, transverse, dark lines is more or less di- 

 stinctly divided into a series of transverse spots; the belly is grey- 

 ish yellow. The vulva consists of a rather large and shallow fovea, 

 which is not longer than it is broad, open behind, and produced 

 somewhat triangularly in front; its elevated side-borders are almost
