Hilaira uncata (Camb.) This rare species seems of pretty 

 general occurrence among Sphagnum on our moors, and has 

 been taken in some numbers on Eston and Easby Moors, 

 and at other points in Lonsdale. 



Coryphaeus distinctus (Sim.) I had the pleasure of taking 

 this species at Linthorpe on November 27th. This is the 

 first published Yorkshire record. I only secured one female, 

 but I had no chance of searching further, the weather was 

 so bad. 



Coryphaeus reprobus (Camb.) Has occurred on the mud 

 flats at Grangetown. 



Tmeticus huthwaitii (Camb.) Not uncommon under stones 

 on the mud flats on both sides of the Tees Mouth. 



Macrargus rufus (Wid.) Rather common Normanby In- 

 take Plantation, Eston Moor, Guisbrough, Lonsdale. 



Plaesiargus abnormis (Bl.) Common on all the moors. 

 I took one male specimen on Eston Moor with a very curious 

 fungoid growth on the abdomen. 



Pedina scopigera (Grube). Amongst the rushes near the 

 mine on Eston Moor. 



Centromerus silvaticus (Bl.) Wilton, Guisbrough, Nor- 

 manby on the moors, and commonly at sea level at Redcar, 

 also at Linthorpe. 



Centromerus expertus (Camb.) Not common on the Wilton 

 side of Eston Moor, but apparently of more general occurrence 

 at the Normanby side. 



Centromerus prudens (Camb.) Common enough at Eston 

 and at Redcar, forming one of the few known examples 

 amongst the Arachnids of species, having both a maritime 

 and a sub-alpine distribution. 



Centromerus arcanus (Camb.) A rare spider, but not 

 uncommon in Lonsdale.
