the lamina. Seen from below this spine gradually tapers towards 

 the rather obtuse extremity, which is curved rather strongly upwards. 

 At its base, on the anterior or interior side, and almost concealed by 

 it, is seen another much finer and shorter spine curved upwards. The 

 bulbus has also nearer the base, outwards, a small black tooth, 

 pointing downwards and curved somewhat backwards. The vulva oc- 

 cupies a large, arched or elevated area, limited by two more or less di- 

 stinct, low, coarse, f-formed ridges curved from each other and strongly 

 converging behind: the costse are outwards limited by a large shal- 

 low depression of corresponding curvature: these depressions show a 

 low shining tubercle posteriorly, by which they are imperfectly di- 

 vided into two fovese or depressions each: the four fovece form a tra- 

 pezium much broader in front. — Dr Koch has kindly supplied me 

 with one male and a few female specimens of L. riparia C. Koch 1 ). 



I) I possess a spider from the nortli-westem parts ot Herj eadalen (the 

 mountain of Fun'asdal etc.) of which the female is so nearly allied to L. riparia 

 J, as to be distinguishable from it perhaps only by the coxae being of the same 

 rusty- or brownish-yellow colour as the rest of the legs, not of a paler yellow, 

 as in L. riparia ?; the male on the contrary, as may be seen from the follow- 

 ing description, differs very much from the spider which I, with L. Eoch, take 

 to be the male of L. riparia.
