and the limestone at Totara are all exactly tlie same series.* McKay also 

 correlates the limestone at the Kakanui with that at Totara.f

The series of Cainozoic rocks on the western side of the North Island 

 from Kawhia to Palmerston is lying almost horizontally. There appears 

 to be no imconformity throughout, and there is the same order of deposits 

 as fou^nd in North Canterbury, Nelson, and elsewhere. The lower members 

 of the series are, however, exposed in the north only as far south as Tau- 

 marunui. They have been divided into different series from the Cretaceous 

 to the Pliocene, { but on general principles only. Bell§ regards them as 

 Tertiary, and mainly Miocene ; Park|| as mainly Pliocene, though the 

 lower members are classed as Miocene. The most noticeable point about 

 the development of the rocks in this area is the great thickness of the upper 

 members of the series : the grey marls are probably not less than 2,000 ft. 

 thick. 



(/.) North Auckland. 



Recently a careful survey has been made by Clarke of the Whangaroa 

 district.^ The Kaeo series as there described is formed of the yomiger 

 rocks. It consists of conglomerates, tuffs, concretionary shales, massive 

 limestones, greensands, and calcareous sandstones. It is, however, doubt- 

 ful whether this is a conformable series. If it is so, it strongly resembles 

 the series developed in North Canterbury.

As elsewhere in New Zealand, the succession and relationships of the later 

 sedimentary rocks immediately to the south and east of Auckland have 

 been interpreted in more than one way. Most of the interpretations have 

 probably attracted little notice. In his widely known " Summary of the 

 Geology of New Zealand,"** however, Hutton gives a section illustrating 

 his conception of the relation between the representatives of his Pareora 

 and Oamaru systems between the Wairoa River and Howick. He gives 

 no detailed account of the section beyond saying that it "' is hard to imder- 

 stand but is quite clear. The Pareora system has been shown by Mr. Cox 

 and myself to lie quite miconformably on the Oamaru system in the Auck- 

 land Province." In an earlier paperff he says, " At Turanga Creek we 

 find the water-worn surface [of the Papakura series] covered by a series 

 of yellow clays and sandstones which form part of the Waitemata series 

 of Professor Hochstetter." He also gives a section {loc. cit., pi. xxvii, 

 sec. iv) with which the section given in Q.J.G.S. agrees in essentials. 



General. — After a complete examination of the district, and specially of 

 critical localities, the author has come to the conclusion that the following
