64 CATALOGUE OF THE SPIDERS OF 



Teesdale, Wolsingham Common under stones throughout the 

 year. May be found at any time clinging to the under surfaces 

 of loose stones, especially in woods and on the moors. Along 

 with it, in March and April, may be found Ccelotes atropos (in 

 its silken sac), Bathyphantes concolor, and B. nigrinus, all adult ; 

 sometimes also Segestria senocidata, in a silken sac, adult ; and 

 occasionally Linyphia montana and Lycosa amentata, immature. 

 In such company, and in the same months I have taken immature 

 specimens of the rare Cicurina cinerea and the rarer Cryphoeca 

 diver sa.

 quoted will serve to distinguish the two.
