The fossil is interesting, as being the first of the genus 

 Scaphites found in New Zealand, and Professor Hutton thinks 

 it is the first that has been found in the Southern Hemisphere. 

 Further, it is interesting as settling the question of the identity 

 of the rocks about Cape Turnagain and the valley of the Wainui 

 Stream. 



From a recent inspection of the rocks in the district between 

 Kaikora, near Waipawa, and Pourere on the north, and the 

 Wainui Stream on the south, I conclude that the rocks through 

 which the latter stream flows mostly belong to the middle and 

 lower cretaceous, and that the fossil ScapJiites comes fi'om the 

 pale- blue and grey chalk which underlies the greensand. 



I propose naming the fossil Scaphites hectori, in honour of 

 Dr. Hector, the head of tke Geological Survey of New Zealand. 



Key to the description of the fossil after Nicholson : — 

 1. Class — Cephalopoda. 



2. Order — Tetrahranchiata. 

 3. Family — Ammonitidce. 

 4. Genus — Scaphitea. 



5. Species — Scaphites hectori. 



Where found: Patangata County, North Island, N.Z. 

 Locality : Wainui Stream, south of Cape Turnagain. 

 Date: September, 1886. 

 Formation : Cretaceous.

Plate XXIII. 



I. — On Monday, the 11th January, during the morning, I left 

 Eosalie Bay, situated on the east of the south end of the Great 

 Barrier, in a boat, rounded Cape Barrier, crossed Tryphena 

 Harbour, arriving at Blind Bay in the afternoon. 



From Blind Bay to the Hot Springs No. 1 there is a fairly 

 good track, the walking being quite easy, and the surrounding 

 country not being devoid of interest to both the botanist and 

 geologist ; but as my time was limited, and my special object 

 was to examine the springs, I could not, though I much 

 wished, search amongst the vast masses of volcanic rock and 

 abundant growth of plants found skirting the heights of the 

 White Cliffs.
