Fossils from Kai Iwi. 



In this locality collections were made for a distance of three-quarters 

 of a mile south of the mouth of the Kai Iwi Stream. The collection was 

 made by one of us (Marshall) in a single day's excursion, and it is probable 

 that the list will have a large number of additions made to it in the 

 future.
