Type: Zetragnatha extensa (LINN.) 
To this genus, generally understood as comprising the compass as- 
signed to it by LATREILLE and WALCKENAER, KEYSERLING ?) also reckons 
a spider, Æugnatha filiformis Sav. and Aup., which by WALCKENAER and 
SIMON is referred to Uloborus, and in WALCKENAER forms the "3"* Race" 
of that genus’ "1" famille” 3). It certainly belongs to the sub-family Zpei- 
rine, and approaches much nearer to Zetragnatha than to Uloborus, but ap- 
pears to us, on account of its agreement with Ulodorus in the relative length 
of the legs and the position of the eyes, by its shorter maxillæ, its abdo- 
men of almost thread-like dimensions and drawn out in a point, ete., to 
deserve to be considered as the type of a separate genus. We have else- 
where *) proposed to reserve to that genus the name of Æugnatha, under 
which SAVIGNY and AUDOUIN united WALCKENAERS Tetragnatha with that 
writers Uloborus filiformis (loc. cit.) *). — The spiders, which WALCKENAER 
(loc. cit., p. 219) classes under the genus Tetraynatha’s 2" family, with the 
name "Coadunate", KEYSERLING, as we have just seen, refers to Meta 
KocH. It seems to us that they ought rather to form a separate genus be- 
twen Meta and Tetragnatha. The "3"* Famille" of 7etragnatha W ALCK., ” Lé- 
zardiformes”, (loc. cit. p. 224) might also well be separated from Tetragnatha 
LarR., and that genus be thus restricted to the compass, which it originally 
had in LATREILLE and in WALCKENAER’S Tableau des Aranéides. — The di-

5) Near this genus Eugnatha (Sav. and AUD.) stands DOLESCHALL’s Ariadne (Bijdr. 
tot de Kenn. d. Arachn. v. d. Ind. Arch., p. 410) by the relative lengths of the legs 
and the form of the abdomen (which is still more drawn out behind the spinners and 
thread-like), but the position of the eyes is quite different. As the name Ariadne 
had been already in 1825— applied by Sav. and Aup. for another genus of spiders, 
we have (p. 37) proposed to exchange the name Ariadne DOLESCH. for Ariamnes.
