about double as many on the interior as on the exterior claw. The chief 
part of the claw forms almost a right angle with its base. The claw-tuft 
varies greatly; in the larger species it is strongly developed, especially on 
the 4" pair of legs, where the hairs are long and thin and more numerous 
than on the 1* pair, and almost similar to the tuft-hairs of Chiracanthium. 
The claws themselves are also on that pair considerably longer than on the 
1" pair. The palpal claw is small and without teeth.

BLACKWALL refers the species of this genus to Clubiona. By C. 
KocH it was singularly enough reckoned among the ” Theridides” (Uebers. 
d. Arachn.-Syst., 5, p. 22). Concerning Anyphena SIMON, vid. sup., p. 144 
under head of Gen. 5. Anyphena. 
The tarsal claws are of the same form as among the Philodromine 
in the next sub-order: they are small, long, slender, almost straight, except 
at the extremity, where they are bent into a hook. They spring at a right 
angle from a slender, high base: the inner claw has on the underside about 
15 coarse, short, vertical, conical, somewhat sparse comb-teeth, that gra- 
dually increase in length; on the outer claw the number of teeth is some- 
what less. The claw-brush is very thick and longer than the claw itself; 
its hairs are long and slender, slightly broader just at the extremity (as in 
Micrommata). The palpal claw is toothless, as in Clubiona.
