Ar. virescens Linn. (Syst. Nat., Ed. 10, I, p. 623), which 

 Sciiranck refers to this species, does not belong to it, but to Dolo- 

 medes Jimbriatus (Clerck). — What spider is intended by Ar. vire- 

 scens Fabr. (Ent. Syst., II, p. 408) "viridis abdomine cylindrico nigro, 

 pedibus anticis longissimis", I do not know. — That the Spar, ligu- 

 rinus of C. Koch (Die Arachn., XII, p. 89, Taf. CCCCXVI, fig. 1020) 

 is a variety of Micr. virescens, as that author himself suspects, seems 

 to me but little probable. The vulva is in M. ligurina truncated 

 behind , whereas in M. virescens its posterior edge forms an obtuse 

 angle; in a ^-specimen from Dalmatia, which I think belongs to M. 

 ligurina (though its tarsi and metatarsi are not reddish), the process 

 of the tibial joint of the palpi is at the extreme apex truncated and 

 slightly notched, not, as in M. virescens S, conically pointed.

According to Westring, in this species the male's palpi are pre- 

 cisely similar to those of M. virescens, which might justify a doubt 

 as to whether M. ornata be really a distinct species. 1 have myself 

 seen only imperfectly developed specimens of M. ornata, and cannot 

 therefore venture to pronounce an opinion.
