attachment of the mother to her cocoon is really surprising. 

 The web may be taken up with the cocoon attached ; and the 

 mother unwilling to leave it, suffers herself to be carried with it, 

 without manifesting the least fear. This may be enclosed in a 

 box, and she will remain by it, apparently contented, if it is not 

 torn from her care. 



1. Phillyra mammeata. 



PI. 14, fig. 16. 



Desci'ijytion. Brownish ; abdomen with diagonal blackish 

 lines more or less distinct ; one tubercle on each side anteriorly; 

 varied with brown and blackish underneath ; anterior pair of legs 

 very long and stouter than the rest ; the antepenultimate joint 

 with a tuft of blackish bristles above and below near the apex, 

 and usually a pale ring at the base; the other legs varied with 

 whitish and brown. 



Observations. This spider makes a horizontal web, usually 

 in cavities, among large logs, or in hollow trunks of trees. It 

 shakes its web violently when threatened ; and when at rest, 

 being always under it in an inverted position, extends its legs in 

 a parallel line, like Tetragnatha. Its cocoon is made in the 

 shape of a double cone or cylinder, tapering at both ends. It is 

 whitish, with veins of brownish black, and has many small, 

 sharp tubercles. The mother watches it with an incredible 

 perseverance, and cannot be separated from it by any induce- 

 ment that can be offered. Fear seems to be wholly merged in 

 maternal solicitude ; and, as soon as the cocoon is torn from its 

 place, having remained firmly attached to it, she proceeds to 

 secure it with new threads. 



Habitat. Alabama, in dry places. [^6.]

 like tail, and is surrounded with six nipples ; legs arranged
