HuTTON. — Geolo<iy of the Treiissick Basin. 405 



here mentioned is "No. 240, below Weka Pass stone, Porter 

 River;"* but on looking over bis list for the fossils collected 

 here I was surprised to find that none are recorded. (4.) Also, 

 if the large development of tufis and scoria in Coleridge Creek 

 belonged to the Waipara System, there would certainly be some 

 indications of them in the upper part of the creek, between the 

 lower limestone and the marl, which is not the case.

t Mr. Enys informs me that a very large shark's tooth — probably

 able to secure it. !
