Tertiary coast-line.” It is hard to imagine how such an interpretation 
could have been given to anything that I have written. Soon after I 
had be an investigation of the geology of the Upper Cretaceous and 
Tertiary formations of New Zealand, more than ten years ago, I was forced 
to adopt the view that there had been continuous sedimentation in the 
New Zealand area from the Upper Cretaceous (Senonian) to the Pliocene. 
In all districts where there has been a close examination of the stratifi- 
cation it is agreed that no hiatus of any importance can be discovered, 
and in nearly every case it is admitted that the series of younger rocks 
is not interrupted by any period of discontinuity. From the palaeonto- 
logical standpoint, however, there have been great difficulties in showing 
that the faunas run on from one to the other without any sudden change. 
in much higher beds. It is only at Wangaloa that a fauna generally 
recognized as of Danian age has yet been found, though, as is now 
generally admitted, that of Hampden has close affinities with it. It is 
to be hoped that future work will discover additional collecting-grounds 
from these lower members of the series, and thus enable us to find out 
definitely if faunas with intermediate features have existed, as one would 
naturally be led to believe from the nature of the stratification. The 
Wangaloa fauna than does any other Tertiary fauna of New Zealand. 
The chief elements of the fauna that show its antiquity are species of 
the genera Trigonia, Gilbertia, and Dicroloma (Alaria).

of these. 
а paper published in 1920 (Trans. N.Z. Inst., vol. 52, p. 112) I drew 
attention to the relationship between the Hampden and the Waihao faunas; 
but stated that up to that time only very small collections had been made 
from the Waihao beds. During the past summer a collection was made 
by Mr. Murdoch and myself at McCullogh’s Bridge. Some sixty-two species 
were found, and this collection, combined with those made by previous. 
collectors, gives us a much more accurate knowledge of the fauna of those 
greensands which lie directly beneath the Waihao limestone, which 18 |
