spider, which Ohlert considers as the female to his E. longimana, 

 is distinguished, among other marks, by a row of small spines on 

 the external egde of the anterior surface of the mandibles, which 

 spines are absent in the cf : the edge of her cephalothorax is also 

 said to be sometimes occupied by scarcely visible small spines (Ohl., 

 loc. cit.)- — Argus longimanus Walck. (Ins. Apt., II, p. 346) is the 

 same as E. longipalpis Sdnd., Westr., as we have already mentioned 

 under that species. 



The specific name vagans is indeed older than longimana, but 

 as another Erigone had already received from Savigny and Audouin 

 the name of vagans, Blackwall's Neriene vagans ought to be called 

 Erigone longimana C. Koch.

Although Blackwall in his short description says nothing of 

 the surface of the sternum of his Neriene nigra, but mentions spi- 

 nes on the legs (meaning doubtless thereby fine bristles or upright 

 hairs) , I have on the strength of the description and figures in other 

 respects exactly suiting Westring's species, no hesitation in append- 

 ing to that species Blackwall's specific name nigra, under which 

 name it has also been sent to me by Cambridge. — The fine hairs 

 on the head of the cf have been overlooked by Westring, and in fact 

 are sometimes worn off. 



Erigone longimana c? Ohl. probably belongs to this species, 

 but the clypeus of cf of E. nigra (scabristernis) is not, as is said to 

 be the case in E. longimana Ohl., "plotzlich eingezogen" under the 

 eyes, and the distance between the posterior central eyes is double, 

 not equal to, the diameter of the eye. — The female of E. longimana 

 Ohl. is another species: vid. preceding article, E. longimana "W estr. 



Of a species nearly allied to E. nigra, and distinguished by 

 its incrassated anterior tibiae, E. (Neriene) tibialis Blackw. 1836
