is known as the Middle Track, the marls similar to those at 

 Najjier ate to be met with among the higher rocks only. The 

 lower rocks are classed by Mr. McKay as belonging to the 

 Te Ante limestones. If such is the case, I venture to disagree 

 with Mr. McKay in his conclusions that " the Napier lower 

 limestones are not the equivalents of the Te Aute limestones." 

 There is no doubt in my own mind that the limestones behind 

 Havelock correspond stratigraphically with the Napier lower 

 limestones ; and I believe that palseontological evidence will 

 shortly be forthcoming to prove the correctness of this state- 

 ment. 



I have purposely omitted all reference to the fossils collected 

 in the different beds to which reference has been made, my aim 

 having been to show, as far as I could, (1) that the fScinde 

 Island rocks are made up of three distinct series, which are 

 unconformable to one other ; and (2) that the uj)per Napier 

 limestones are related to the limestones to the N. and N.W. of 

 Napier, whilst the lower limestones have their equivalents in 

 what have been termed the Te Aute limestones.
