again as the two preceding joints put together; the lamina has a 

 strong, angular protuberance at the base; the bulbus is tolerably 

 complicated, with a crooked appendage at the base, outward, which 

 appendage is smaller, especially as regards its breadth, than that of 

 E. sihatica; it is produced at the base in a backward directed angle; 

 when viewed in profile from within, the bulbus exhibits on the un- 

 der side a strong spine or claw pointing forwards and slightly 

 curved upward, which appears to be cloven at the extremity (?). The 

 thighs of the two anterior pairs of legs are provided each with a 

 fine spine or coarse bristle. These notes are from a dried male 

 specimen lent me by Westring. The female is not with certainty 

 known to me. 



A S preserved in spirits, which I have received from the late 

 Prof. Al. v. Nordmann in Helsingfors, appears to differ from We- 

 string's specimen, as far as I could see, only by the clypeus being 

 somewhat, though very little, higher than the area of the four cen- 

 tral eyes, whereas in Westring's specimen the height of the clypeus 

 and of that area are equal: Westring's statement that the height of 

 the clypeus is not "insigniter altior quam spatium inter oculos inter- 

 medios anticos et posticos", is therefore not strictly correct. 



I cannot think that this spider is identical with Micryph. 

 cequalis C. Koch 1841 the description of which differs in many 

 respects from Westring's spider : it is a least quite distinct from the 

 species , to which Ohlert 2 ) has applied the name Micryph. cegualis 

 C. Koch, and of which he has kindly sent me a $ : the vulva in that 

 species, as Ohlert states, exhibits a fine, linear, pinlike process some- 

 what thickened at tip and directed backwards! 



Bathypkantes brevipalpus Menge <J is certainly identical with 

 Westring's E. cequalis. The description agrees very well, as far as it 

 can be verified on dried specimens (I have no others now at hand), 

 and I have therefore called this species E. brevipalpis (Menge).
