2, PHILLYRA RIPARIA. . 
Plate III. Fig. 17. 
Description. Whitish; cephalothorax with two longitudi- 
nal, brownish, narrow bands; abdomen with an interrupted 
longitudinal line and two lateral curved lines, blackish ; one 
tubercle above near the middle on each side ; feet varied with 
blackish, antepenult joint of the anterior pair with two tufts of 
bristles. Markings of the female pale and indistinct. 
Observations. This was found on limestone rocks, on the 
banks of Cypress Creek. It certainly differs from P. mam- 
meata. 
Habitat. North Alabama, in moist places. 
' TETRAGNATHA. Latr. 
Characters. Cheliceres long, serrated, or with prongs; 
mazille parallel, very long, widening at the top, truncated ; 
lip subtriangular, less than half the length of the maxilla ; 
palpi long and slender ; eyes eight, subequal, in two nearly 
parallel rows of four each ; feet long and slender ; first pair 
longest, then the second, the third being the shortest. 
Habits. Araneides sedentary, forming a web composed of 
spiral threads crossed by other threads departing from the 
centre, and abiding on the web with their legs extended lon- 
gitudinally. | 
marks. This subgenus is closely related to Epeira, and 
has nearly the same habits. The species composing it are 
readily recognized by their long legs extended upon their geo- 
metrical webs. They differ greatly in the length of their 
cheliceres, butin other respects constitute a natural subdivi- 
sion.
