AGELENIDA5. 
Family AGELENIDiE. 
No continent on the face of the globe is without representatives of the Agelenidae, which 
have the falces articulated vertically or on an inclined plane. Their abdomen is provided 
with three pairs of spinners and with two branchial opercula, and the tarsi are usually 
terminated by three, rarely by two, claws. 
Bushes and coarse herbage, crevices in rocks and walls, holes in the earth, the under¬ 
side of stones, and the inside of buildings, are the situations most commonly occupied by 
the spiders of this family. For the purpose of insnaring their prey they construct a sheet of 
web, varying in extent, and having, in numerous instances, a tube connected with it, which 
either leads to or constitutes the retreat of the spider. This web is attached to objects 
in its vicinity by its margin, and frequently derives additional support from fine lines, 
intersecting one another at various angles, whose extremities are in contact with its surface 
and with objects situated above and below it. 
Genus AGELENA, WalcJcenaer. 
Lyes disposed on the anterior part of the cephalo-thorax in two transverse, curved rows, 
whose convexity is directed backwards; they do not present any very remarkable difference 
in size. 
Maxillae short, powerful, somewhat oval or quadrate. 
Lip large, nearly quadrate, or inclined to oval. 
Legs moderately long; the fourth pair is the longest, then the first, and the third pair is 
the shortest.
