continuation of the “ Antarctandes” of Graham's Land — the formerly 
views may be reconciled. While, with Gregory and Wilckens, we may 
consider as most probable the continuation of the axis of late Mesozoic 
the trough of Ross Sea. This correlation is the more easy if we accept 
Henderson’s (1917) view that the movements of block-faulting occurred 
at intervals during the Cainozoic period in New Zealand, which is not 
in any way incompatible with the trend of physiographic evidence in 
eastern Australia, as interpreted by Andrews (1910). 
Professor David’s (19148) map of the trend-lines of the circumpolar 
region supports the suggestion that we may take the zone of the Otago 
schists and New Zealand Alps as representing the continuation from King 
Edward VII Land of the circumpacific folds. Such a zone would leave 
would not, therefore, attach much significance to Hector’s (1870) com- 
parison of the mica-schists of Chatham Islands and Central Otago. An 
z hes т compares this rock with that of Auckland Island, and believes that
