the bridge over the Otiake Stream. The limestone is of an arenaceous 

 nature, and contains a great number of fossils. Near its base there is a 

 thin band of greensand, which contains many specimens of Isis dactyla, 

 Magellania sp., and Pecten kuttoni. 



The following is a list of the species obtained during two days' collecting 

 from a face of arenaceous limestone some 50 ft. in height : —

All Day Bay. 



In this locality the lowest rock is a volcanic breccia commonly known 

 in New Zealand geology as the Waireka tuffs. A bed of limestone about 

 12 ft. thick rests on the breccia quite conformably. The upper surface of 

 the limestone is remarkable for the abundant remains of species of Isis. 

 This upper surface is somewhat uneven, as is generally the case in New Zea- 

 land when the limestone is succeeded by a bed of greensand, which is the 

 case here. The greensands gradually become argillaceous, and within a 

 thickness of 50 ft. they pass into a material that cannot be distinguished 

 from the Awamoa beds, which five miles farther north are clearly seen at 

 the Rifle Butts to have exactly the same stratigraphical position. No 

 lists of fossils from this locality have been published previously. The
