ones larger ; abdomen pale, piceous, with a sub-obselete spot 

 near the base, four nipples, two external ones bi-articulate. 

 Feet long, 1. 4. 2. 3. 



Observations. The difference between the eyes of this and 

 those of my Cluhiona ohesa prevents my referring them to the 

 same species. The pulmonary orifices are white, under a 

 gloss. This spider made an even* web like Agelena. Wan- 

 dering at night. 



Habitat. Alabama. 



[PI. 18, fig. 29, eyes. The two external nipples of the ab- 

 domen are the longest ; the body is of the same color beneath 

 as above. Taken in April. Supplement.'] 



4. Clubiona tranquilla. 



PI. 10, fig. 16. 



Description. Deep rufous or piceous ; abdomen grayish 

 black, with four impressed dots. [451.] 



Observations. It is difficult to learn much of the habits of 

 this spider, which moves chiefly at night. A male and a fe- 

 male were found in Alabama in July, in the folds of an old 

 piece of paper, near a silk tube of extreme whiteness, which 

 was probably destined to receive the eggs. Always found in a 

 tube except at the approach of winter, Avhen it is sometimes 

 found wanderino;. 



Habitat Common in the United States.

 emarffinate, first pair of legs longest.
