130 DR. A. RANDELL JACKSON ON THE 



An examination of the actual types of the above species 

 shows their identity. An example sent to Professor Kulczynski 

 settled the identity of his species. Specimens exchanged with 

 Mr. Simon proved the same as regards the S. aeria of " Les 

 Arachnides de France." 



This little species occurs amongst grass and herbage within 

 woods and on sandhills near the coast. It is adult in 

 September, and has been found in Dorset, Gloucester, 

 Glamorgan, Essex, and Warwick.

(Plate VII., figs. 5, 5a, 5b, 5c.) 



Tibiae i. and ii. show a long strong spine on their posterior 

 borders between the middle and apex. 



Male palpal tibia shows, at the distal end, a large median 

 apophysis curving towards the outer side. 



Lamella characteristica very complicated and difficult to 

 see without dissection. It presents on its- upper border four 

 very diverse processes, and one wonders whether the whole 

 organ is homologous with the lamella characteristica of the 

 other species, or whether a part only should be so interpreted. 



Epigyne very broad and characteristic. Mr. Cambridge 

 gives an excellent figure (sub M. passiva), in which case the 

 drawing was made from below and rather behind. 



The external genital organs and the lateral spines on the 

 first two pairs of tibia? will enable this spider to be recognized 

 with ease in either sex. 



Mr. E. Simon, to whom I sent examples, informs me that 

 the species is identical with his M. rustica.
