C. Kocn erroneously refers (Die Arachn., VIII, p. 105) Linn^us' 

 and Sundevall's Aran, or I An. rufipes to his Micryph. ecespitum (E. 

 cvistata (Blackw.), E. bieomis Westb.): Conf. Thor., Kec. crit. Aran., 

 p. 57. Even if the citation from Linnaeus be considered uncertain, 

 still rufipes is the oldest specific name, and, if we refuse to call this 

 spider E. rufipes (Linn.) 1758, we must call it E. rufipes (Sund.) 1830. 



Neriene rufipes Blackw. 1833 ') is a different spider. — Of Mi- 

 oryph. crassipalpus Ohl. the female only (of which he has sent me 

 specimens) belongs to E. rufipes Westr. : the description of the male 

 does not answer to that species. Oiilert says for example of its 

 mandibles (loc. cit, p. 70), that, as in the female, they are destitute, 

 of teeth on the fore side. — Another species of Erigone, which may 

 keep the specific name crassipalpis , is Lophocarenum crassipalpe 

 Menge 2 ), concerning which vid. supr., p. 118. 



(Pag. 261.) 34. E. dentifera [= Erigone dentifera Westr. 1861]. 



This species is very closely allied to E. graminicola, but the 

 form of the mandibles etc. is different (see Westring's description): 

 it is, however, perhaps but a variety of that species. Other species, to 

 which it is allied, are Neriene afifinis Blackw. 1855 3 ) — which is 

 certainly identical with Tmeticus leptocaulis Menge 4 ) — and Ner. 

 Huthwaitii Cambr. 1861 5 ); but it is easily distinguished from both. 

 In E. affinis or leptocaulis, the patellar joint of the palpi in c? is 

 more than double as long as it is broad, rather longer than the patella 

 of the l:st pair of legs, whereas in E. dentifera it is short, and, as 

 in E. Huthwaitii, shorter than the patella of the l:st pair, conical, 

 scarcely double as long as its own breadth at the apex; the spine 

 under the apex of the patellar joint in E. afimis, is either absent
