thicker than the thigh of the first pair, the lamina as long as the 

 femoral and patellar joints together, almost elliptic, and not nar- 

 rower towards the apex, scarcely half as long again as it is broad, 

 the bulbus large, brown, somewhat broader towards the apex, some- 

 what obliquely united with the lamina. In II. nam cf the pro- 

 cess on the patellar joint points almost directly outward, and is bent 

 upwards towards the extremity; it is about as long as the patellar, 

 but shorter than the femoral joint; the clava is scarcely thicker than 

 the thighs of the 1 st pair, the lamina not quite so long as the femo- 

 ral + patellar joints, slenderer towards the extremity, oviform; the 

 bulbus also is oviform. 



As regards the real H. montana (Blackw.) 1841 ')i it is, according 

 to Blackwall, "inconsiderably larger" than II. nava: a cf specimen of 

 this species in my collection (kindly given me by Cambridge) is very 

 like a c? of H. nava, but is somewhat larger and in colour (in 

 which however there is said to be considerable variety) paler, reddish 

 brown: the outward-pointing process on the patellar joint is shorter, 

 coarser and blunter, shorter than the patellar joint itself; the lamina 

 is scarcely longer than the femoral joint.

That Hahnia pratensis Menge (Preuss. Spinn., Ill, p. 253, PL 

 48, tab. 150), which is identical with Agelena elegans Blackw. 1841 2 ), 

 is a spider totally different from Westring's H. pratensis, the most 

 desultory glance on the descriptions of the male's palpi given by 

 these writers sufficiently demonstrates. The two species are easily 

 distinguished by the following characteristics, which apply to both 

 sexes. In Westring's spider, which is not a ffahnia, but a Cry- 

 ftkceca, the anterior row of eyes is straight, the anterior central eyes 

 considerably smaller than the anterior lateral, and not larger than 

 the posterior central eyes, and the spinners are disposed in a trape- 

 zium. In Ilahnia pratensis Menge, or Agelena elegans Blackw., the 

 anterior row of eyes is bent forwards (downwards), the anterior cen- 

 tral eyes are largest of all, double as large as the posterior; the 

 long spines under the anterior tibiae and metatarsi in Westring's 

 spider are here absent; the spinners are arranged in a transversal
