Mr. W. Cole tells me that a spider’s nest, shaped like an 
inverted wine-glass (but afterwards plastered with mud), and 
attached to twigs of broom, rushes, &c., is commonly found 
in the Forest. This is probably the nest of one of the only 
two spiders at present known in England as forming such a 
one —Agroeca brunnea, Blackw., or A. proximo,, Cambr. (Fam. 
Drassidae) ; either or both would be likely to occur in Epping 
Forest. 
[As the above is the first paper on the Arachnida which 
has been communicated to the Club, it may not be out of

cally studying these creatures, which we take from the 
Introduction to Mr. Pickard-Carubridge’s valuable work, 
‘ The Spiders of Dorset,’ above referred to. The directions 
will be of great service to any of our members who may be 
inclined to take up the study and collecting of spiders and 
allied animals;—
