There seems to be but one species of Leptograptus in the above series, 
and it is closely allied to, if not identical with, L. flaccidus, J. Hall. 
None of the specimens, however, show the sicular or thecal characters 
sufficiently clearly for more: exact determination. I was at first inclined 
to regard them as obscure examples of Dicellograptus, but a careful 
examination convinces me that they 1 are Leptograptidce. The* specimens 
of C. bicornis are typical, and not the Stockyard Creek (N.S.W.) variety. 
The age of the beds is clearly Upper Ordovician,, and not far removed 
from the other beds of that age herein dealt with. 
From the Cornish line of Reef, Daylesford. 
(Nos. 462-478. Collected by Mr. W. H. Ferguson). 
Didymograptus bifidus, J. Hall; Nos. 462, 463, 473 (?).

T. fruticosus, J. Hall; Nos. 464, 465, 468 (a form with two stipes

Phyllograptus typus, ]. Hall; Nos. 465, 467, 477. 
Indeterminate; Nos. 466, 472, 473, 475. 
Crustacean; No. 470. 
The age is Lower Ordovician (Bendigonian horizon), and, as is shown 
by the presence of Didymograptus bifidus, the beds are at the top of the 
Bendigo series and correspond to those displayed in Wattle Gully, Chewton.
