patiki beds, which clearly overlie the Petane clays and sands." 

 Here the Napier limestones are placed above the Petane clays, 

 as seen in the inner harbour ; but, although this classification 

 has been made, Mr. McKay is clearly doubtful on the point, 

 for he says a little further on, " Whatever the ultimate con- 

 clusion arrived at may be, there seems no likelihood that the 

 lower limestone in Scinde Island will be referred to the Pare- 

 ora system of Hutton."

 includes — (a) Mahia beds, consisting of pumice-sands, sands, 

 and clays, overlying the limestones on the west side of the 

 Mahia Peninsula ; (b) the Waipatiki beds, including an upper 

 and a lower shelly limestone, parted by a series of sandy clays 

 and pumice-sands ; (c) the Kaiwaka beds, which comprise the 

 typical Petane clays and sands, and the pumice-sands, con- 

 glomerates, and brown sands of the Esk Valley and Kaiwaka 

 Creek." 



4. Page 205, older Pliocene, Poliui series : " This includes 

 the triple sandstone conglomerate and other beds of Eangi- 

 mapapa Hill, and the Pohui grey and brown sands, .... 

 also the shelly limestones of Te Whaka and the Maunga- 

 haruru Eange, and, as a consequence, to this should be 

 referred the Te Aute limestone in the southern part of the 

 district." 



5. Pages 206-7, Eangimapapa beds : " These beds have not 

 been proved fossiliferous in the district south of the Mohaka 



[Eiver ("?), 39th parallel] . On the north bank fossils have been 

 obtained from what should be the same beds. The collection 

 . consisted mostly of recent shells." 



6. Page 202, Petane clays : " These are best known . . . 

 along the north and western shores of Napier Harbour. 



. To the south-west they extend across the Tutae- 

 kuri into the Ngaruroro Valley, in vvhich they form charac- 

 teristic strata underlying the Petane limestones 



Farther to the south-west the clays overlying the Te Aute 

 limestones along the eastern side of the Euataniwha Plain may 

 belong to these beds ; but in this case the lower members of 

 the Kaitvaka beds tvoiild have to be considered absent, as also 

 n-ould the Itangimapapa and the Pohui beds."
