Tur material for the following paper, which I received through the 
kindness of Professor W. N. Benson, of the University of Otago, Dunedi 
consisted of fifty-six specimens of otoliths, the property of the Geological 
urvey of New Zealand, and seventy-one otoliths collected Mr. H. 
inlay, M.Sc., of the University of Otago, to whom I am also indebted for 
a list of the formations, in their proper sequence, from which they were 
obtained. I wish also to acknowledge the great assistance I have received 
from Professor Benson in his letters, and from the literature he has so 
y sent me on the present nomenclature and correlation of the various 
systems of New Zealand. 
The list of the localities and probable age of the beds from which the 
otoliths have been obtained are as follow
