FAMIL Y —BALTIC ID A E. 



Salticus scenicus (Clk.) Common on ash trees, walls, 

 fences and gate posts. Can be seen any sunnj r day in June 

 stalking its prey. I have seen it in town running up and 

 down a wall at the top of Abingdon Road. There is a fairly 

 strong colony on a fence near the Park. 



Salticus cingulatus (Panz.) This rather rare spider has 

 occurred freely in several places ; abundantly at Ayton 

 under bark on larch trees, one in a wall in Lonsdale, common- 

 ly on Pinus sylvestris on Kildale Moor, and one on a gate 

 post at Nunthorpe. 



FAMILY— AGELIN ID AE. 



Cryphoeca silvicola (C.L.K.) A very common spider 

 among the pine needles and under bark at Eston and Ayton, 

 and on Kildale Moor. A northern form. 



Cryphoeca (Sp. ?) An immature individual of the genus 

 Cryphoeca, not referable to C. silvicola, was taken on Eston 

 Moor. I believe the specimen was in a nest of Lasius niger. 



Ccelotes atropos (Walck.) Another northern spider found 

 under stones on all the moors. Extraordinarily abundant 

 in the quarry on the brow of Eston Nab. 



Tegenaria derhami (Scop.) This is the common house- 

 spider of the district, although I have found both of the two 

 common Amaurobii in houses here. 



Textrix denticulata (Oliv.) Very common in the walls 

 crossing the moors. 



FAMILY— HAHNIIDAE. 



Hahnia montana (Bl.) Common enough in moss on all 

 the moors.
