 Neriene cornuta (Bl.) One female on Eston Moor. 



Dismodicus bifrons (Bl.) Very common on whin bushes 

 at Nunthorpe, Gunnergate, Hesleden, &c. 



Gongylidium ruflpes (Sund.) Not very common amongst 

 crowberry (Empetrum nigrum) at Eston and in Lonsdale. 



Gongylidum agreste (Bl.) Found sparingly in October 

 on Eston Moor and near the Toll Bar on Marton Road. 



Gongylidum fuscum (Bl.) Occasionally turned up in 

 Lonsdale. Not uncommon in Middlesbrough. 



Gongylidium retusum (Westr.) Found in fair numbers 

 under stones in Greatham Marsh. It seemed odd to take 

 these and shrimps under the same stone. Also taken in 

 Lonsdale. 



Gongylidium tuberosum (Bl.) This was discovered fairly 

 freely in June at Ayton amongst rushes and was not un- 

 common at Eston in October. 



Gongylidium gibbosum (Bl.) Barely separable from the 

 last species, but not uncommon at Eston and in Lonsdale. 



Erigone dentipalpis (Wid.) Common on all the moors, 

 and not uncommon near Middlesbrough. 



Erigone atra (Bl.) Pretty generally distributed. Not 

 uncommon amongst grass in the Park. 



Erigone arctica (White). This species formerly considered 

 so rare that Mr. Walsh's specimen taken among stack refuse 

 at Marton formed the only Yorkshire record, has proved 

 very abundant in all suitable spots. I took it at Grange- 

 town in February, and in very large numbers at Redcar in 

 November. Originally recorded from Spitzbergen. 



Maso sundevallii (Westr.) Has been found not uncom- 

 monly at Eston, Guisbrough and Lonsdale, and once even 

 in Middlesbrough.
