south this white material becomes somewhat harder, and then is succeeded 

 rather abruptly, but along an uneroded stratification-plane, by a dark- 

 grey marly bed. Forty yards farther along the foreshore these beds are 

 succeeded along another parallel stratification -plane by a more arenaceous 

 bed with some tufaceous material. These beds form the prominent Pakau- 

 rangi Point at the north-west end of the Funnel. In previous reports 

 this point has been generally called Komiti Point, and the beds of which 

 it is formed have been called the Komiti Point beds. This, however, is a 

 misnomer, and it is likely to lead to much confusion, as Komiti is at the 

 other end of the Funnel and is now the location of a considerable settle- 

 ment of fruitgrowers.

These Pakaurangi Point beds, under the name of the Komiti Point 

 beds, have been correlated with the Waitemata series of Auckland, which 

 is referred to the Miocene period. The stratification of these beds is much 

 disturbed on both sides of the Funnel. The upper members, especially 

 as seen on the south side of the Funnel, have a highly variable strike, 

 and they are composed of coarsely tufaceous material, amongst which are 

 numerous fragments of hydraulic limestone. The presence of these frag- 

 ments does not, in the opinion of the author, imply erosion of the lime- 

 stone before the Pakaurangi beds were deposited. Their occurrence in this 

 tufaceous material is rather due to volcanic action, which was extremely
