with Blackwall's type-specimens of E. anthracina, and has informed 

 me that it exactly agrees with that species. As regards C. Koch's 

 S. anthracina*), that author's figure and short description perfectly 

 suit S. pygmcea (Sund.) cf, to which Blackwall and I have referred 

 it: according to our opinion, S. anthracina C. Koch is not an 

 independent species, but the male to Shiga trifasciata C. Koch oi- 

 ls', pygmcea J. Ausserer 2 ) however does not adopt this identifica- 

 tion, but gives the name 5. anthracina to another, very nearly allied 

 species, which I suppose cannot with more probability than E. an- 

 thracina Blackw. be proved to be the true S. anthracina C. Koch. It 

 is certainly best to drop that name, and to distinguish S. anthracina 

 Auss. by a new denomination: I propose to call it S. Ausse.re.ri. 



Ausserer describes loc. cit. as the male of S. sanguinea C. Koch 3 ) 

 a spider, which, according to his account, differs from his 5. anthra- 

 cina or S. Aussereri n. $ by the bulbus having a very fine, rather 

 long, slightly curved process a little below the great tooth, and by 

 the colour of the abdomen being brownish red with dark sides: in 

 S. Aussereri $ on the contrary the said process is stated to be absent, 

 and the abdomen to be piceous, with sometimes a pale spot at the 

 base, above. Dr L. Koch has given me, under the name of "S. sangui- 

 ned $?" an adult male, which has the above-mentioned fine process 

 on the bulbus, that according to Ausserer distinguishes S. sanguinea 

 $, and this specimen accordingly must belong to S. sangdinea Auss., 

 notwithstanding its brown abdomen having a short pale centre 

 stripe at the base, as is stated to be sometimes the case in S. Aus- 

 sereri. (The presence or absence of such a spot or stripe appears to 

 be of no consequence). I have lately sent this male specimen to Mr 

 Cambridge, who has also in England captured similar males, and 

 who considers them to belong to E. Herii Blackw., which he ac- 

 cordingly takes to be identical with 5. sanguinea. This how- 

 ever appears to me but little probable: I possess a German female 

 Singa, which unquestionably is the true S. sanguinea C. Koch, and 

 which is very different from Blackwall's figure of E. Herii and 

 from English specimens of this species sent me by Mr Cambridge: 

 the abdomen is reddish brown with three yellowish spots in front, 

 one in the middle and one on each side, and two large black spots
