eminence is as figured in Menge's L. anticum. Eeuss indeed was only 

 acquainted with the female, but the difference of colour between E. 

 antica and E. flavida (Menge) — the last has yellowish legs with yellow- 

 ish brown fore-tibise — clearly indicates, that Reuss' synonym is as cer- 

 tain as the others that we have admitted under E. antica Westr.

Blackwall's specific name has , as we see , priority in preference 

 to both Keuss' and C. Koch's. — Micryphantes punctulatns ') C. Koch 

 1836, taken by Walckenaer as a synonym to his Argus bicornis, is 

 without doubt an entirely different species. — Of the synonyms adduced 

 by C. Koch under Micryphantes ccespitum (Die Arachn., loc. cit.), the 

 only one really belonging to that species is, as Westring observes, 

 Ther. bicorne Reuss: Einyphia rufipes Sund. (Aran, rufipes Linn.) is 

 identical with C. Koch's Micryph. crassipalpus. To refer, as Koch 

 has done, the Greenlandish Aran, rufipes 0. Fabr. (Fauna Grcenl. , 

 p. 226) to this species, is of course an entirely arbitrary proceeding. 



A cf specimen of Walckenaera cristata Blackw. from England 

 has been kindly sent me by Mr. Cambridge. — Theridium cristatum 



l) Not "Micryphantes punctatus", as Walckenaer writes the name. Vid. 

 Die Arachn., ILT, p. 12. — Another separate species is E. (Walckenaera) punc- 

 tata Blackw. 1841 (Spid. of Gr. Brit., n, p. 295, PI. XX, fig. 210; PI. XXH, 

 fig. A): it is identical with Microneta scrobiculata Menge (Preuss. Spinn., HI, 

 p. 227, PI. 44, tab. 126), as is also Lopliomma stictocephalum Menge 3 (ibid., II, 

 p. 210, PI. 41, tab. 108), according to specimens of both these forms with which 

 Menge has favoured me.
