Blackwall complains with reason of the scanty and insufficient 

 character of most existing descriptions of E. angulata , "which render 

 any attempt to reconcile the perplexed synonyma of this species almost 

 hopeless." In my Eec. crit. Aran.') he might however have found 

 a circumstantial description of the E. angulata of the Swedish Arach- 

 nologists, and, for the sake of comparison , also of two closely allied 

 South-European species, E. Schreiberm Hahn (unquestionably identi- 

 cal with E. coruuta Walck., which C. Koch and Blackwall errone- 

 ously refer to E. angulata) and E. regia C. Koch, Thor. — Among 

 older authors at least Ltnne , De Geer and Fabricius have by their 

 Ar. angxdata meant the right E. angulata (Clerck); Rossi's A. an- 

 gulata is perhaps a collective name for E. Schreibersii and E. regia. 

 Ar. angulata Sulzer is according to C. Koch = E. patagiata (Clerck) ; 

 Ar. angulata Schrank (Enum. Ins. Austr., p. 527), which "habitat 

 in urtica dioica et urente," is at any rate not = E. angulata (Clerck), 

 and perhaps = Meta segmentata (Clerck). 



Walckenaer's E. angulata appears to include not only E. regia, 

 but also the true E. angulata. The above cited synonyms derived 

 from Sundevall and Menge are perfectly certain; Hahn's E. angu- 

 lata (Die Arachn., II, p. 16, fig. 108) belongs decidedly to the same 

 species, as do also C. Koch's synonyms adduced above, probably even 

 his E. pinetorum, of the male of which Koch says that it has the 

 tibiae of the 2" d pair strongly incrassated, clublike 2 ). Ohlert's E. an- 

 gulata (Aran. d. Provinz Preussen, p. 32) is moreover a certain sy- 

 nonym for E. angulata (Clerck). The species described under this 

 name by Blackwall is probably the same, but if so, the female seen 

 by him, and the vulva from which he has figured fig. 259, e, must 

 have been an imperfectly developed specimen; for in the full-grown 

 female the vulva displays a long, almost ^-formed "scapus," simi- 

 lar to that of E. Nordmanni, E. diademata and some others. 



In E. angulata and E. regia C. Koch, Thor., the corpus, from 

 which that long scapus proceeds, exhibits on the posterior or upper 

 side (i. e. that turned towards the belly) two longitudinal furrows 

 uniting at the base, by which the corpus is divided into three por- 

 tions , of which the two outer include the central one in an almost horse- 

 shoe-formed enclosure; in E. Schreibersii the corpus vulvae has on 

 that side only one longitudinal central furrow, while in E. grossa it
