TRAP-DOOR SPIDERS. 289 



one or two special distinctions observed between the 

 two male examples examined. It should however be 

 noted that in one (the one captured behind a stone 

 wall) the ocular area was slightly narrower in propor- 

 tion to its length, and the interval between the eyes 

 of each lateral pair rather less.

The examination of an adult example of each sex 

 of this spider received from M. Simon, by whom they 

 were found in Corsica, leads me to conclude that we 

 have here the true jSI . meridionalis, Costa, as certainly 

 at least as it is possible at present to identify the 

 species by the insufiicient description and figures 

 given by this author. 



The eijes appear to be less closely massed together 

 than in N. Mandersijernce, but in other respects no 

 particularly tangible difference is to be noted ; the 

 interval however between the eyes of each lateral pair 

 is perhaps rather greater. Between the male and the 

 female of the present species there is a decided diffe- 

 rence in the relative position of the e3^es. In the 

 female the fore-centrals are nearer together than each 

 is to the fore-lateral on its side, while in the male, the
