Park (1910) has suggested that the Chatham Island ridge “ is the eastern 
wing of the great synclinal in the trough of which lie the folded Mesozoic 
rocks that compose the Alpine divide and the parallel ranges of the 
Dominion lying to the eastward.” The importance of the fracture-lines 
traversing and often limiting the New Zealand area, and their general 
obliquity to the axes of the Cretaceous folding, have been emphasized by 
seismic activity in the Tongan trench and in the eastern suboceanic slopes 
of New Zealand (Hogben, 1914) may afford evidence of the continuance at 
the present day of the conditions that led to the formation of the south- 
Western margin of the Pacific. Marshall’s (1911) outline of the margin 
would bring into accordance with this the seismic activit у 
Hebrides indicated by the Rev. E. Е. Pigot’s seismometric investigations 
at Riverview, Sydney. 
urning to the palaeontological evidence of the relationships of Austral- 
asia through the Antarctic with South America, we note that Taylor 
(1914) has recognized close allies of South Australian species of Archaeo- 
cyathinae in a limestone from South Victoria Land, and Gordon (1920) 
America, but this was emphasized in the papers 
е ), the latter declaring that South 
ona,» Antarctica, and New Zealand formed at that period part of the 
continuous southern coast of the Pacific Ocean.
