area may have been littoral to a Southland - Chatham Island continent, 
not glaciated, nor supporting Glossopteris, rather than to the Australian 
mainland. Neither drifted erratics* nor Glossopteris have been proved to

series (in its restricted sense), this last point may not be very significant, 
and does not appear to vitiate the suggestions in the map.

the first view, has concluded (19174), since Trechmann’s description of 
the Maitai fossils, that a break of some kind must occur between these

Otago which may be either of dynamical or glacial origin. He inclines to the latter 
tion. They appear to be in “ Maitai " rocks.
