more systems. So far as the Lower Tertiaries and Upper Cretaceous 

 are concerned the reason for this is ohvious. Of all the areas covered 

 by the Bulletins issued by the new Survey, in the Kaeo district alone 

 (Bulletin No. 8) were the Lower Tertiary and Upper Cretaceous 

 formations present. In their report on this district Dr. Bell and 

 Mr. E. de E. Clarke took particular pains to point out the obscurity of 

 the sections, and after discussing the situation go on to say l : "It will 

 be seen that in the Whangaroa subdivision the sum-total favours the 

 view that the Kaeo Series should be divided into an older portion of 

 Mesozoic age and a younger portion of Tertiary age, or, in other words, 

 that a Cretaceo-Tertiary system is not represented." 



A classification of the New Zealand formations was drawn up in 

 1907 for the Geological Survey by Dr. Bell, the Director, Mr. A. McKay, 

 some time Government Geologist, and myself; and although this 

 classification was recognized as a compromise that did not exactly 

 express the views of any one of us on all points, it did not find room 

 for a Cretaceo-Tertiary succession, the Lower Tertiary and Upper 

 Cretaceous being placed in two separate systems, that is in the Oamaru 

 and Waipara systems respectively. Moreover, I have good authority 

 for saying that the present Director, Mr. Percy G. Morgan, does not 

 recognize a Cretaceo-Tertiary system. The fact is that while flagrant 

 unconformity may exist between two formations, places may be found 

 where deceptive physical conformity may exist, as so well shown by 

 Professor Watts in his Geology, fig. 153, p. 221. 



The differences that exist between the views of Ilutton, myself, and 

 others as to the Waipara section cannot be regarded as proof of 

 a complete succession, but are rather suggestive of the difficulty that 

 had to be faced in the interpretation of a section that seemed to be so 

 opposed to the palaeontological evidence. 



A fine succession of the Upper Cretaceous is exposed at Amuri Bluff, 

 but as no Lower Tertiary rocks are known there the relationship 

 cannot be established between the two systems in that district.

Davies referred to Terehella (?) leioesiensis four specimens said by him 

 to be in the J. R. Capron Collection, purchased for the British Museum 

 in 1879. "Two casts from a quarry near Guildford," he wrote, 

 ' ' which admirably show by impression the membranous or horny 

 structure of the tube, bear no indication of the attachment of any 

 foreign substance." The quarry is Cowslip Pit, near Guildford, and 

 the Chalk appears to be Cenomanian, possibly of the Holaster sub- 

 globosus zone. The two specimens are believed, on the evidence of 

 Davies' labels, to be those now registered A 1574 and A 1575. 

 "These," continues Davies, "may be referred to the same species
