gether with this or the typical species, also Clubiona nutrix WALCK., which 
he however some time afterwards detached from Anyphena and united with 
a couple of other species into a new genus, Chiracanthium. To take, as 
SIMON has done, the generic name of Anyphena for just these species, which 
SUNDEVALL never referred to that genus, is of course an error. 
L. KocH has discovered (vid. loc. cit., p. 194) that Anyphena is 
distinguished by both sexes having on the underside of the abdomen, some- 
times in the middle of the belly, sometimes a little fore or aft of that point, 
a small transversal groove or fold of the skin. I imagine that in this groove 
there are one or two tracheal stigmata, as is the case with e. gr. Argyro- 
neta aquatica, which has a similar groove under the anterior part of the 
belly. (Vid. sup. p. 136). 
The tarsal claws of A. accentuata are rather small, strong, with 
about 14—20 long, closely set comb-teeth on the inner claw and only about 
half that number on the outer. The claw-tuft is formed of uncommonly 
broad, flattened, platelike hairs, which are dilated outwards, cut almost 
transversely at the extremity, and somewhat longer than the claw.

Type: Clubiona holosericea (DE GEER). 
This genus is still preserved almost in its original compass, as more 
accurately limited by WALCKENAER, by, for example, BLACKWALL, who 
however detaches from it the species, which, in consequence of their having 
an infra-mammillary organ and calamistrum, he refers to Ciniflo (Amau- 
robius). 
The tarsal claws of these spiders are rather long, almost straight, 
curved only at the extremity, closely pectinated with long, strong teeth, 
1) The usually received etymology, x4éoc, fame; from, live, seems highly im- 
probable. — Perhaps the name is formed of »Awßiov, a bird-trap (with reference to 
the sack-like tube which these spiders inhabit).
