As Westring was the first person who accurately distinguished 

 and separated these species, it is best to preserve, as Blackwall 

 and Cambridge have done, the specific name given by Keuss, denti- 

 palpis, to the species described by Westeing under that name, al- 

 though it cannot be proved, that it was just that species and not 

 f. inst. E. atra (vagabunda) — which Menge calls E. dentipalpis — 

 that is to be considered as indicated by Keuss' description and figure. 

 — Mr Cambridge has communicated to me specimens of E. dentipal- 

 pis Weste. under the name of Ner. dentipalpis Blackw.; I have also 

 received that species from L. Koch under the name of E. dentipal- 

 pis. — See also the next preceding and following species.

Of the spider described by Menge in his Preuss. Spinn. under 

 the name of E. dentipalpis, that arachnologist has himself obligingly 

 sent me specimens. On the synonyms of this species see the two 

 preceding, E. longipalpis Weste. and E. dentipalpis Weste.

l) When the above articles on E. longipalpis Westr. etc. were already- 

 printed, I received a letter from Mr Cambridge, in which he informs me that 

 E. vagabunda Westr. (of which, as well as of E. longipalpis Westr., I had sent 

 specimens to him) is identical with the genuine E. atra Blackw. As this latter 

 name has priority, it must be preferred to that given by Westring.
