It cannot but appear singular, that all the writers who have 

 described "Salt. (Att. or Marp.) brevipes", should have seen only the 

 female of that species, whereas on the other hand C. Koch had 

 only seen the male of "A. heterophtholmus" (and Blackwall similarly 

 only the male of Salt, obscurus). Reuss and Simon indeed mention 

 also the female of 8. or A. heterophthalmus , but so briefly, as not 

 to give any clear idea of the spider they had before them. (Westring's 

 A. heterophthalmus, a female, is quite a different species, whereof 

 more hereafter). This circumstance is easily explained if we sup- 

 pose n A. heterophthalmus" to be the male to "A. brevipes"; and that 

 this supposition is true, I am fully convinced. This my conviction 

 has been further confirmed by my receiving from Cambidge a <$ and 

 % from England under the name of "S. obscurus Blackw.", of which 

 the female is identical with the spider that I, with Westring, con- 

 sider to be C. Koch's Marpessa brevipes, and of which Simon was 

 kind enough to favour me with a specimen under the denomination 

 of A. brevipes Sim., whereas the male is just the spider, which I 

 have looked upon as the male to this A. brevipes, and which Reuss', 

 C. Koch's and Simon's descriptions of 8. or A. heterophthalmus most 

 accurately suit. Add to this, that Simon (loc. cit.) says, that he re- 

 ceived from Cambridge the very type-specimen of S. obscurus Blackw.
