without any glass, thus showing a distinct connection with the trachytes. 

 The ferro-magnesian elements consist of the usual hypersthene and augite, 

 some of the latter in fairly large crystals and beautifully twinned. 



It will thus be seen that there is a very close resemblance in the rocks 

 of White Island to those of the great volcanoes lying in the middle of the 

 North Island, and to the rocks, recently described by Bartrum,* occurring 

 south of Tauranga, in the Te Puke district, although thfse last evidently 

 belong to a much earlier period. 



Art. XLIII. — ■Additions to the List of Fossils from the Lower Waipara. 



By R. Speight, M.Sc, F.G.S. 



[Read before the Philosophical Institute of Canterbury, 5th November, 1913.] 



The following list of fossils is based on collections made by the author last 

 January on the banks of the Waipara River, about a quarter of a mile 

 below Greenwood's Bridge, and opposite to the point where Double Corner 

 Station was once situated. The beds consist of sands and sandy clays, 

 with occasional hard concretionary bands which strike north-west and dip 

 south-west at angles in the vicinity of 15°. They represent one of the 

 higher horizons exposed in the gorge, and pass up conformably into the 

 beds exposed near the mouth of the Waipara River, which here consist of 

 clays with occasional layers of coarse shingle, and seams of lignite which 

 have a marked resemblance to the beds exposed on the south-eastern 

 flanks of Mount Grey and form the Mount Grey Downs. No fossils have 

 been found in these beds, but the lithological resemblance is so close that 

 they may be assumed, at any rate tentatively, to be of the same age. 



The greater number of the fossils enumerated in my former paper on 

 this locality were from a lower horizon, which is well exposed on the high 

 banks somewhat higher up the river, about a mile above the bridge. My 

 reason for publishing this list is merely to help as far as possible in the 

 elucidation of our Tertiary sequence, for, as matters now stand, the collec- 

 tion of fossils in particular localities, with due regard to zoning, is the most 

 pressing work to be done, and therefore I have ventured to submit this 

 list, although it is a comparatively short one. I am indebted to Mr. Henry 

 Suter for his kindness in aiding materially in the identification of the forms.
