to occur in our fauna, and there are doubtless others which are 

 as yet undescribed. 



The six species described below are our more common ones; 

 the following table will aid in separating these:

Clubiona abbotii (C. ab-bot'i-i). — This is the smallest of 

 our common species, measuring only from one sixth to one fifth 

 inch in length. The cephalothorax is light yellowish brown. 

 The ground colour of the abdomen is lighter than the cephalo- 

 thorax; but there is a reddish brown lanceolate median stripe 

 on the basal part; and the hind part is mottled with reddish 

 brown. The space between the posterior median eyes is nearly 

 twice as great as that between one of them and the posterior 

 lateral eye of the same side. The epigynum (Fig. 640) is pointed 

 behind, with a notch in the middle; and at some distance in front 

 of it two dark objects, probably the glands of the spermathecae,
