uppermost eyes is not greater than the diameter of an eye, and the 

 eye-area's height (length) is greater than its breadth, etc. 



That Walckenaer's synonym belongs to this species and not to 

 E. lliorellii, I will not venture decidedly to affirm; perhaps, like 

 the names that he quotes, it includes both species. 



(Pag. 231.) 19. E. CraSSiceps [= Erigone crassiceps Westk. 1861]. 



The type-specimens of this species are preserved in my cabinet. 

 The tibial joint of the male's palpus has on the upper egde of 

 the apex, outwards, a fine, slender, straight process; on the inside 

 it is drawn out into a large, convex, thin appendage, which at its 

 base lies upon the lamina bulbi, with which it is almost equal in 

 length; it is broad at the base, tapering and curved upward at the 

 extremity: the apex itself is again somewhat dilated, and divided 

 by a small, almost semicircular notch into two short teeth. The 

 bulbus exhibits on the under- side, nearer to the extremity, a pair 

 of fine, curved spines directed outward. The species is nearly allied 

 to Walckenaera humilis Blackw. 1841 ') = Tjophocarenum globiceps 

 Menge 2 ), but in E. crassiceps the head is more projecting ; when the 

 cephalothorax is viewed from the side, the head at the back part 

 rises more steeply and rounded off, after which it is almost hori- 

 zontal, but slightly convex, and the forehead (the area between the 

 centre eyes) projecting, rounded-arched, not longish and almost 

 truncated; the clypeus is much more strongly inclined backwards. 

 Viewed from before the head is sligtly and regularly convex above, 

 not, as in E. humilis (Blackw.) , truncated or rather a little hollowed 

 out in the middle. — Of E. humilis, which has not hitherto been 

 recorded as Swedish, Dr. Haglund has captured two male specimens in 

 Ostergotland.
