Grroup Ateaoe^. 



The two genera Atrcix Cambr. and Hadronyche L. Koch, which I 

 have detached to this group, differ considerably from either of the 

 two previous genera. 



The sternal sigillse are large and removed from the margin, and 

 the teeth on the falx-sheath are in two rows on interior and exterior 

 margins, with an intermediate row of small ones at the lower end. 



The superior spinnerets are short and the inferior even closer 

 together than in Brachythele ; while the tarsal claws are pectinated 

 in one row across the claw as in Macrothele, and the lip very thickly 

 bespined.
