ARACHN1DA. 
deut-ovum stage (of Claparede) seems to be merely the strengthening of 
the inner membrane, as the outer (chitinous or coriaceous) covering of 
the ovum splits, and forms a weak place for the extrusion of the larva. 
This stage belongs to some of the Oribatidce as well as to A tax bonzi , 
Clap., and Trombullum fuliginosum , M6g. Somo wood-boring species are 
remarked upon, also the moultings of Liosoma palmicinctum , p. G ; at 
p. 8, it is stated that no instance is recorded of any species of this 
family being habitually predatory. Five new species are described and 
figured.
