 however, brought the nomenclature up to date : — 



1. Pleurotoma latescens, Hutton. 



2. Natica gibbosa, Hutton. 



3. Natica ovata, Hutton. 



4. Turritella gigantea, Hutton. 



5. Turritella. ambulacrum, Sowb. 



6. Scalaria lyrata, Zittel. 



7. Bent alium gig ant cum, Sowb. 



8. Cardium patulum,, Hutton. 



9. Cardita dijficilis, Desh. 



10. Cucullaa alta, Sowb. 



11. Pecten hochstetteri, Zittel. 



12. Pecten hutckinsoni, Hutton. 



13. Waldheimia lenticularis, Desh. 



14. Waldheimia triangularis, Hutton. 



15. Waldheimia (?) concentrica, Hutton. 



16. Cellepora nummularis, Busk. 



17. Fasciculipora ramosa, Busk. 



18. Caratomus (?) miperus, Hutton. 



Of these eighteen species, ten give no evidence as to the 

 position of the Mount Brown beds, being either confined to 

 it or else found equally commonly in both the Oamaru and 

 Pareora Systems. Of the remaining eight species, none are 

 exclusively Oamaru, but two are found principally in that 

 system. The other six belong principally to the Pareora 

 System, one of them, Cardita dijficilis, not having been recorded 

 as yet from any part of the Oamaru System. The paheonto- 

 logical evidence, therefore, such as it is, is in favour of the 

 beds belonging to the Pareora System, and, from a strati- 

 graphical point of view, the unconformity lends support to 

 this view. 



The Hutchinson's Quarry beds at Oamaru have always been 

 considered, for palteontological reasons, as the equivalents of the 

 Mount Brown beds ; and last year I showed* that probably 

 they rested unconformably on the Ototara limestone, and 

 belonged to the Pareora System. 



It now appears that the Mount Brown beds have strati- 

 graphically a similar position, and also belong to the Pareora 

 System. 



Again, the beds immediately above the upper limestone in 

 Trelissick basin were referred by Mr. McKay (together with the 

 upper limestone itself) to the horizon of the Mount Brown beds ; 

 but last year I showed that they formed the base of the Pareora 

 System at that locality.! Consequently the view now put forth,
