78 THE GEOLOGICAL FORMATIONS OF NEW ZEALAND 
The occurrence of these saurian remains, together be the : 
survival of many permian forms into the Wairoa and e 
‘Otapiri series, and the absence of true Spirifers, rode a : 
other usual paleeozoic elements of a permian fauna, would seem to 
connect the Kaihiku series rather with the mesozoic than the 
palzozoic formations of New Zealand. 
At the base of the Kaihiku series are the Glossopteris beds of 
Mount Potts, but these were not found in the Hokanui section, 
although from the thickness of the strata the relative beds must 
be included in it, while in the Kaihiku range Glossopteris ¢ Qoomes
