The arrangement and relationship of the different beds at 

 this place are shown in fig. 5. 



«-/ 



Section of Sea-cliff north of Cape Wanbrow. 

 a. Yeilow Pleistocene silts, b. Agglomerates and tuffs, c. Bedded tuffs. 

 d. Greensands and tuffs, fossiliferous. e. Coralline limestone, 3 ft. 

 to 3*5 ft. thick. /. Thin-bedded blue clays, g. Rubbly calcareous 

 ash-bed, with thin layers of limestone from 2 in. to 6 in. thick near 

 the upper part. h. Yellowish-green ash-bed, 18ft. to 20ft. thick; 

 fossiliferous. i. Sands, silts, and ash, current-bedded ; no fossils. 

 /. Pillow-form lava and agglomerates. 



Fossils. 

 From bed d I collected the following species : — 



1. Pecten hutchinsoni, Hutton. 



2. Pseudamussium huttoni, Park. 



3. Magellania norara, Jhering. 



4. Terebratella gaulteri, Morris. 



5. Terebratulina oamarutica, Boehm. 



Also numerous corals and Cidaris spines. 



The same species were also collected from beds e and/. 

 From bed h I obtained a greater variety of molluscs, in- 

 cluding the following forms : — 



1. Ostrea wullerstorfi, Zittel. 



2. Glycimeris globosa, Hutton. 



3. Venericardia awamoaensis, Harris. 



4. DiplodonUi. zelandica, Gray. 



5. Pecten hutchinsoni, Hutton. 



6. Pecten williamsoni, Zittel. 



7. Pseudamussium huttoni, Park. 



8. Limopsis insolita, G. B. Sowerby. 

 Also cup-shaped bryozoans and corals. 



Proceeding southward from the point formed by the pillow- 

 form lava and agglomerates, the latter are seen to be under- 

 laid by thin-bedded tuff's dipping northward at angles varying 

 from 15° to 17°. At the base of these tuffs there is a band of 

 rubbly coralline limestone from 8 in. to 12 in. thick, containing 

 angular fragments of basalt up to 8 in. in diameter.
