The most interesting point about this collection is the occurrence of 
Tetragraptus approximatus along the Hustler’s line, near Hustler’s Hill. 
This has not been recorded previously from Bendigo, and in spite of the 
large amount of material from the district I have examined at various 
times, I had not recognised its presence. We have in this species, I 
think, an indication of the possibility of zoning the thck Bendigo series, 
as evidently! diversity in the fossils exists. T. approximatus has previously 
been found near Dromana. by Mr. Ferguson, and the rocks there I 
had indicated as of 'Bendigonian age. All the other species here recorded 
from the Hustler’s line are common Bendigonian species and, excepting 
the restricted T. fruticosus , pass up into higher beds.
