1. INTRODUCTION. 
'Hie existence of a Triassic flora in tlie Bacclius Marsh District 
was suggested and tentatively field by geologists for many years, 
but the evidence luid been obscured by the confusion of two horizons. 
Thus, Sir Kredk. Mct'oy was always impressed with tlie 'Priassic 
aspect of the Bacchus Marsh flora as a whole ; and the earlier 
mistaken view, that the “ Fchizoneura bed occurred beneath the 
(Fmgamopteris sandstone of Bacchus Marsh, only added to the 
difficulty. 
Writing in 1892, McCoy^ said that he recognized Lower Triassic 
rocks in specimens obtained by W. H. Ferguson “ from a newly 
discovered bed just under the famous Gmigamopteris sandstone of 
Bacchus Mar.sh,” in which he identified Schizoneura and Zevgo- 
phyllites. 
Apjiarently the error of inverting the relative positions of these 
two beds arose through a slip in draiving the preliminary sketch, 
though Mr. Ferguson correctly represents in sketch-section Xo. 1, 
sent to the National Museum on 29th July, 1891, the (FinganiopterF 
beds underlying the adjacent rocks that contain the ScJuzoneura 
flora (see text-fig. pi. 128). 
In some notes on glacial de[)osits of Bacchus Marsh, Messi's. 
OHicer and Balfour^ refer to xMcCoy's determination of Schizoneura 
and Ftilophyllum from this locality, and state They all come from 
the Sehizoneti'm bed a thin clayey band about 4 inches in width. 
TTe horizon is appareiitly above that of the Ganyamopteris beds.
