The collection contained no mature specimens, only immature 
ones. 1 his circumstance is probably due to the season in which 
the collection was made- -July to November. Probably the 
time of sexual maturity is confined to the season from January 
to April. 
The author was only able to determine one nearly mature 
specimen : — 
Tnaenonyx aspera, Pocock (?). — Pinjarra, Lunenberg, Brunswick, 
and Bridgetown.
