the posterior ones, is identical with E. dromedaria Walck. The 

 statement, that the coxae of the 2 nd pair of legs are on the upper 

 margin armed with a tooth, is a lapsus calami; the tooth or thorn in 

 Menge's spider is situated on the underside of the coxa? of the first 

 pair of legs, as Menge has kindly informed me in a letter. — E. 

 bicornis C. Koch (Die Arachn. XI, p. 92, Taf. CCCLXXXIII, fig. 

 902, 903) is probably identical with E. bicornis Walck. and Blackw. , 

 with which it agrees in size. This is also the case with the spider 

 which Sill describes under the name of "E. bicornis Koch" (Zweit. 

 Beitrag etc. 1 ), p. 201: "Lange 2— 3 "). 



The specific name bicornis ought however not to be retained 

 for any one of the species here mentioned. It had already been 

 given by Gmelin 2 ) to a spider described by Lepechin 3 ) and nearly 

 related to E. angulata, perhaps identical with E. regia or E. Sckrei- 

 bersii, and which afterwards received from Krynicki 4 ) the name E. 

 Lepechini. The species called by C. Koch E. bicornis ought to be 

 named E. arbustorum C. Koch, by which name it is described in 

 Uebers. d. Arachn.- Syst. , l,p. 3. It is however very probable, that 

 some of the species described by Walckenaer under the names 

 E. gibbosa, E. cruciata and E. furcata is only a variety of his E. 

 bicornis, which I suppose is quite as variable in the colour of the 

 abdomen, as are E. angulata, E. omceda and E. dromedaria.
