GRAPTOLITES OF VICTORIA. 
meshes and in its apertures. Ruedemann (13) records large 
medial meshes in Retiolites, but the apertures in the form here

from Locality Ba 56 and 57, Quarter Sheet 1 NW, north-west 
of Keilor, is very indistinct and imperfect ; better specimens 
have since been obtained, both from the type locality and 
from Enoch’s Point, some of which we have made plesiotypes.
