TETRAGRAPTUS FRUTICOSUS SERIES 
(Bendigonian Zones) 
He correlated the Diplograptus series with the Llanvirnian 
of Britain and suggested that the correlation of beds imme- 
diately below these will probably be facilitated by a study of 
the Victorian extensiform Didymograpti. 
He published a map with notes, a section, an index to 
graptolite localities and a list of references. 
W. H. Lang and I. C. Cookson (139) contributed a paper 
on the flora, including vascular land-plants, associated with 
Monograptus, in rocks of Silurian age. They submitted the 
associated graptolites to Gr. L. Elies, who identified M. unci- 
natus var. orhatus from the Yarra Track beds and M. 
chimaera, M. uncinatus var. orlatus et var. micropoma from 
the Alexandra beds ; she regarded the assemblage typical of 
a Lower Ludlow horizon (110 and 128).
