ATYPUS BLACKWALLII, 



Atypus Blackwallii, Sim., Cambr., Ann., and Mag. N. H., 

 Octr., 1875, s. 4, vol. xvi., p. 241. 

 This species is nearly allied to the foregoing, and closely 

 resembles it in general form, size, and colours. It may be 

 distinguished, among other characters, by the crushed-in appear- 

 ance of the falces at their base on the inner sides. Two British 

 examples only have been recorded, and one of these was found 

 by myself at Portland, near Pennsylvania Castle, some years ago. 

 The above examples have been examined and determined by 

 M. Simon ; I must, however, confess to some doubt in regard 

 to the goodness of the species, or at any rate in respect to the 

 identity of these examples with the French types. 



ATYPUS BECKII, 



Atyptjs beckii, Cambr., Ann, and Mag., N. H., s. 4, vol. xvi. 

 p. 242, pi. viii., fig. 1. 

 A female of this spider, which is very like A.piceus, Sulz., in its 

 general appearance and colours, was found some years ago at 

 Portland, near Pennsylvania Castle. It may be distinguished by 

 its rather larger size, as well as by the more abrupt slope of 

 the hinder part of the caput, and by the eyes forming a longer 

 and rather narrower transverse area, on a rather more projecting 

 and more pointed prominence. An adult male, presenting much 

 more strongly-marked differential characters than the female, 

 was given to me by the late Mr. Eichard Beck (of 31, Cornhill, 

 London), by whom it was found near Hastings. 



It is not improbable that this spider will be found eventually 

 to be identical with A. piceus Ausserer, a spider which I have not 

 yet had an opportunity of examining.
