 from within. The male is smaller, almost 

 black, and may sometimes be found moving 

 slowly about in the sunshine in the neigh- 

 bourhood of the colony. The spider has also 

 been recorded under the names A. sulxerl and 

 A. piceus by English authors. 



2. Atypus beciii, O. P.-Cambridge 

 Hastings (R. Beck) 

 This species is that which has been, by 

 continental authors, referred to as A. piceus, 

 Sultzer. It is very doubtful whether this species 

 has ever been taken in this country ; but has 

 probably been recorded for Sussex by mistake.
