Only later, when the so-called boulder-bed* in the Hawkesbury beds 
was made known, I have adopted another mode of correlation, viz., that of 
the Hawkesbury boulder bed with a similar one in the Bacchus Marsh beds, 
and also in the Talchir beds ; but I have sufficiently shown that the corre- 
lation is no more tenable, but that the Bacchus Marsh conglomerate must be 
correlated with a similar one in the marine beds in New South Wales, and 
thus the above table is now again re-established. 
The chief character of a Gcmgamopteris lies in the distribution of the 
veins. They are, speaking generally, distributed radiarily, but form anasto- 
moses, and we can thus say that a Gcmgamopteris is a Glossopteris without 
a midrib. 
There are several species known from Australia, as follows : —
