The two foregoing species occurred in the Hastings district. 

 The females may be easily distinguished under the microscope by 

 the form of the epigynae. See Figs. 7 and 8.

 Brier ley Hill, Staffs. Collections of Porrhommae, especially if 

 they be fairly extensive ones from restricted areas, are par-

 a new species, P. campbellii, based upon a single female specimen 

 found in an extensive collection received from Dr. Campbell. 

 Although I have not had the opportunity of examining the 

 type specimen, nor yet to examine the historical collections 

 which Mr. F. Cambridge had at his disposal during his investi- 

 gations, I hardly feel disposed to accept this species upon the
