806 THE TIME OF THE GLACIAL PERIOD IX NEW ZEALAND, 



that it is a true species, and in no way distorted. The spine is 

 granulated but it does not extend to the last whorl. Mr. Smith 

 states " that the granules are arranged in such a manner as to 

 form oblique series in two directions or in a criss-cross direction ; 

 they are excessively minute and crowded upon the topmost whorls, 

 and gradually enlai'ge and become further apart as the shell grows. 

 In addition to the sculpture already mentioned, there are indications 

 on the body whorl of a few shallow transverse indistinct sulci, 

 with faintly elevated broad ridges between them, especially around 

 the middle. The apex of this species is peculiar ; for the nucleus 

 coils in and downwards and is less raised than the second whorl." 

 The granulation around the spine of this species is very much after 

 some of the Australian forms. 



THE TIME OF THE GLACIAL PERIOD IN NEW 



ZEALAND. 



By Dr. R. v. Lendenfeld, Ph.D. 



In a recent Paper (1)1 described the principal Glaciers of New 

 Zealand of the present time, and I have found occasion several 

 times to refer to the Glacial Period, which has left most striking 

 traces in all parts of that country. 



Von Haast (2) has furnished a Map of the Glaciers of the cold 

 period, which shows that several of the ice-streams of that period 

 extended down to the sea. 



I had occasion to observe the characteristic scratches on the rocks 

 in the Sounds of the West-coast close to the waters edge, which 

 prove the correctness of Von Haast's views. 



The Sounds in the southern part of the West-coast of the Middle 

 Island of New Zealand are a most striking topographical feature. 

 Similar Sounds are found in Norway and Kamtchatka, also there 

 the traces of glaciers are to be seen on their steep sides.
