p. 108) introduced an element of confusion into the 

 question by describing N. carminans as having the 

 point of the palpal organs simple, " nulleraent bifid," 

 and throwing out a suggestion that it might be the 

 male of N. Sauvaf/ii, Latr., { = N. pionniere or 

 fodiens, Walck.) Latreille upon this {Vues generales 

 sur les Araneldes, Acad. Hoy. des 8c. , 1830, pp. 64, 

 65) explains Dufour's suggestion as an inadvertence, 

 but takes no notice of the difference of the form of 

 the palpal organs as described by him ; at the same 

 time however Latreille explains why, probably, Walck- 

 enaer " still considers (in his Faune franoaise) N. 

 carminans to be a distinct species." We may con- 

 clude from this that Latreille never altered his opinion 

 that his own N. cfBmentaria and TV. carminans were 

 the two sexes of the same species ; and we shall pro- 

 bably rightly agree with Walckenaer that Dufourhad 

 another species before him, which he wrongly (I.e.) 

 described as N. carminans. 



Subsequently again a male and female spider, evi- 

 dently of one species, were figured by Dages to 

 illustrate N. camentaria male and female in Cuvier's 

 B.'egne Animal — Edition in 20 vols, not numbered 

 and without date, published in Paris, " accompar/nee 

 de Planches jo^'r une reunion de disciples de Ci/vier, 

 MM. Audouin, Blanchard, Beshayes, Aleide d'Orbiyny, 

 Doyere, Duyes, Biwernoy, Laiirillard, Milne Edwards, 

 Roulin, et Vcdenciennes." Of these figures, that of the 

 male has the point of the palpal organs distinctly bifid, 

 and the nest figured is of the cork -lid type. 



On the whole it may be concluded that the male 

 of the true N. camenfaria, Latr., wdll be found to 

 have the bifid point to the palpal organs, but the
