Transactions. 



The glauconitic greensands of the south Kawa section (see fig. 11) were 

 not traced north of the Kawa Stream. 



(4.) Above the tabular limestones appear fine light-coloured silts and 

 clays. These close the Notocene sequence. 



(5.) Brown sands. As pointed out already, the Notocene beds show 

 folding, and on their eroded surface rest the younger beds.* In 

 most of the sections the brown sands follow the tabular lime- 

 stones unconformably. However, near the Hanwai Creek and the 

 Waikato South Head they rest on beds of fine light-coloured 

 silts and clays, called by Hochstetter (1867) " Pleistocene silts," 

 which contain no fossils. (See figs. 3 and 7.) The brown sands 

 show the characteristic irregular bedding of wind-blown sands, 

 except where bands of silt are interbedded with them in their 

 lower parts. 



(6.) Shifting sands of recent date close the sequence. 



The Kawa Section. 



The most important section shown along this coast is that to the south 

 of Kawa Stream, and referred to herein as the " Kawa section." The well- 

 marked unconformity in the sequence of its strata, the evidence of volcanic 

 activity, and the pumice-bed, 170 ft. to 180 ft. above sea-level, possibly

connecting these beds with the history of the Waikato River, are the features 

 which give it this importance. It was described in detail by Bartrum 

 (1919b). The following brief description contains a few facts not recorded 

 by him. 



Order of Ascending Sequence. (See fig. 11.) 



1. Blue calcareous sea-muds. 



2. Glauconitic greensands (15 ft. to 20ft.). 



3. Above the glauconitic greeesands come 50 ft. to 60 ft. of thin calcareous 



sea-muds. These thin beds, after deposition, were affected by move- 

 ments of compression, resulting in faulting and gentle folding, and 

 accompanying uplift. Then followed a period of planation by the 

 sea which cut their upper surface into a plane of marine denudation. 



4. Fossiliferous yellow sands to a depth of 36 ft. were now deposited by 



the sea on the marine-planed surface of the slowly sinking land. 

 Mr. J. A. Bartrum has published a list of fossils from this bed and 

 has described some new species (Bartrum, 1919a and 1919b).
