appendix to Martini's translation of Lister's famous work (Lister's 

 Naturgesch. d. Spinn., p. 245), which he edited, rebaptized Glebok'b 

 Ar. V insignitus as Ar. navaria. As I have above (p. 353) stated, I 

 do not admit among the synonyms Gceze's appellations, any more than 

 those of other authors who do not consistently observe the now uni- 

 versally adopted binomial method of nomenclature: in determining 

 questions of priority in fact no notice can be taken of names of this 

 description. Vid. Thor., On Europ. Spid. , p. 7. 



Under this species Westring classes Attus litteratus Walck., and 

 in this it appears to me certain that he is right, and that Walcke- 

 naer's A. litteratus is the female of his A. qninqne-partitus. Walcke- 

 naer, it is true, says (H. N d. Ins. Apt., I, p. 403) that the de- 

 scription he had previously (in Faune Franc., Arachn.. p. 41) given 

 of this last species, was taken from a female; but this is evidently 

 a mistake, for the said description only suits the male: the two sexes 

 in this species are very dissimilar (Conf. Rec. crit. Aran., p. 70), 

 and when Walckenaer says: "le male differe peu de la femelle", it is 

 clear that he had no idea of what the real female to his A. quinque- 

 partitus is; whereas the description of "A. litteratus" in Faune Franc., 

 Arachn., p. 43 (PI. 5, fig. 6? 1 )), exactly suits that female. I think 

 therefore that C. Koch and Simon 2 ) are mistaken in identifying A. 

 litteratus Walck. with Ylle?ius festivus (C. Koch) 1834 (= Euophrys 

 striata id., Die Arachn., XIV, p. 1, where Ar. striatus Clerck and 

 Ar. V notatus id. are erroneously taken up as synonyms). It is espe- 

 cially to be remarked, that according to Walckenaer (Faune Franc., 

 loc. cit.) the cephalothorax of A. litteratus has "deux accents noirs 

 proche la tete"; in Faune Par., II, p. 247 it is even said: "?m ou 

 deux v ou accents circonjlecces tun dans V autre" : this is the case in 

 Y. v-insignitus (where these accents form a v, and are bounded on 

 one or both sides by a light stripe) , but not in Y. festivus (C. Koch). 

 When Walckenaer under his A. litteratus takes up Ar. litera V no- 

 tatus Clerck, it is pretty clear, that he had observed this V-shaped 

 mark on his A. litteratus, and that it is to it that the specific name 

 litteratus refers. That Walckenaer himself refers Euophrys /estiva 

 C. Koch to A. litteratus is not of the smallest consequence, as 

 Walckenaer's identifications of most of Koch's Attoid-species appear 



1) In H. N. d. Ins. Apt., I, p. 414, Walckenaer refers to this figure under 

 his A. virgulatus and says: r La fig. 6 est a tort attribute a la lettree" (A. litte- 

 ratus); but nevertheless p. 419 he takes up the same figure under A. litteratus.
