Leptyphantes tenebricola (Wid.) A fair number were 

 shaken from dead leaves at Linthorpe. 



Leptyphantes Blackwallii (Kale). This has the same 

 range as L. Mengii, but is even more common. Has been 

 taken in the town. 



Leptyphantes cristatus (Menge). Not very common, but 

 has been taken in Wilton Wood and near Middlesbrough 



Leptyphantes minutus (Bl.) I have only taken this 

 spider once, at Normanby. 



Leptyphantes nebulosus (Sund.) This very rare spider has 

 occurred in Abingdon Road, Middlesbrough, and under 

 stones on the beach at Redcar. These are the first adults 

 taken so far north in England. 



Liny phi a clathrata (Sund.) Very common everywhere. 

 I have taken it in hedges near the town from old bird nests. 



Linyphia montana (Clerck.) Have beaten this from laurel 

 near Gunnergate. 



Linyphia triangularis (Clerck). Seems very sparingly rep- 

 resented in this district. Has only occurred at Eston. 



Linyphia peltata (Wid.) Beaten fairly freely from the 

 alders in Lonsdale. 



Linyphia insignis (Bl.) Not uncommon in Wilton Wood, 

 and once in dead leaves in Middlesbrough. 



Drapetisca soeialis (Bl.) Very common in the fallen twigs 

 at the base of the firs in Wilton Wood. 



Stemonyphantes lineatus (Linn.) Very common every- 

 where, generally spun up in dead leaves. Shaken from 

 scraps of paper in the Park and elsewhere in the Borough. 



Bolyphantes luteolus (Bl.) Rather common everywhere, 

 but particularly so on the higher moors and on the coast 

 sand-hills at Redcar.
