This genus, which is not received by L. KocH in his.” Die Arachn.- 
fam. d. Drassiden", appears to me to form a transition from the Drassoidæ, 
on the one side to the Agalenoide, and on the other through Zora to the 
Lycosoide. By BLACKWALL a couple of species belonging, as far as I can 
see, to this genus, are referred to Agalena, namely his A. celans and gra- 
cilipes 1), — A. fuscus WESTR. I have found at Kissingen in Bavaria, and af- 
terwards also at Söderköping in Sweden; another species is described by 
AUSSERER ?) under the name of A. saxatilis. 
The tarsal claws of A. fuscus are weak, much curved, and provided 
nearer the base with 4—5 divergent, rather long comb-teeth gradually in- 
creasing in length. On a conical process beneath them are only two, co- 
lossal hairs (the claw-tuft), in the form of flat thin slices, narrow at the 
base, gradually dilated, and cut off obliquely at the broad extremity. They 
are much longer than the claws. The palpal claw, which is weak like 
those of the tarsi, has 2 or 3 teeth pointing forward, near its base. 
To Apostenus or some nearly related genus belongs perhaps Aranea 
spuucrus Dur. *), which however is by WALCKENAER referred to the genus 
Sparassus or Micrommata *), as also Drassus sub-niger CAMBR. loc. cit.

This South-European genus is known to me only by the few words 
with which it is characterized by L. Kocu in the above cited passage. Iam 
not even sure that I have assigned it a right place in my schema, for L. 
KocH does not say that the posterior row of eyes, seen from above, is 
curved backwards, but only: "die hintere Augenreihe durch Tieferstehen der 
Mittelaugen gebogen.”  CANESTRINI and Pavesi 5) refer Trachelas to the The- 
ridioidæ, not to the Drassoide.
