mity, in front ; the fifth joint consists of three parts, one of which projects 

 boldly in front ; this process is curved, glabrous, transversely striated 

 above, and has a thin membrane attached to it ; another part, united to 

 the base of the curved process on the outer side, is slender and hairy ; 

 and the third part, which is much the largest, is oval, convex and hairy 

 externally, and concave within ; all three are connected with the palpal 

 organs, which are moderately developed, rather complicated in structure, 

 and of a reddish brown colour. The convex sides of the oval parts of the 

 fifth joints are directed towards each other. 



This species, like Epeira antriada, to which it is nearly allied, frequents 

 damp caverns, and hollow banks, to the sides of which it attaches its subglo- 

 bular cocoon in the month of May. This cocoon, which is composed of 

 whitish silk of a loose texture, is depressed on the attached side, and mea- 

 sures about half an inch in diameter ; it comprises between two and three 

 hundred spherical eggs of a yellow colour, agglutinated together in a lenti- 

 cular mass measuring T^ths of an inch in diameter.
