702 SUBANTARCTIC ISLANDS OF NEW ZEALAND, [Geology. 



Mereteix, Lam. 

 Meretrix multistriata, Sow. 



A cast somewhat doubtfully belonging to this species was obtained from the 

 breccia near Terror Point. The species does not appear to have been found in the 

 fossil state in New Zealand. 



ALCYONARIA. 



Flabellum, Lesson. 



Flabellum sphenoideum, Ten. -Woods. 



Two portions of casts were found in the breccia of Terror Point. The specific 

 identification is doubtful. 



FORAMINIFERA. 



Many forms are represented in the limestone. It was found impossible to 

 identify the species in the rock-sections, and all efforts to isolate the tests failed. 

 The genera Nodosaria, Glohigerina, Textularia, and Cristellaria r^re undoubtedly 

 represented. 



AGE OF FOSSILIFEROUS ROCKS. 



Of these fossils, none, with the doubtful exception of Conchothyra 'parasitica, are 

 found in rocks older than the Miocene formation in New Zealand. 



It is well known that different authors have expressed very different views 

 as to the age of the Cainozoic rocks of New Zealand. The following statement 

 embodies the main points of the classification adopted by the authors named : — 



Hector* — 



Cretaceo-tertiary, Eocene, Upper Miocene, Lower Miocene, and Pliocene. 



HuTTONf — 



Oligocene : Includes Ototara and Mawhera series of Cretaceo-tertiary of Hector ; 

 also his Eocene formation, except the Mount Brown series. Miocene : 

 Includes Waitemata series of Cretaceo-tertiary of Hector, the Mount Brown 

 series of his Eocene, and his Upper and Lower Miocene. Pliocene. 



ParkJ — 



Miocene : Includes most of Hector's Cretaceo-tertiary, Eocene, and Upper 

 and Lower Miocene (Hutton's Oligocene and Miocene correspond to this 

 formation). Pliocene : Includes the Motanau series, placed by the other 

 authorities in the Miocene. 



If an attempt is made to correlate the Campbell Island limestones with divisions 

 of these classifications, it is probable that this would be their proper position : 

 Hector's classification, Cretaceo-tertiary ; Hutton's classification, Oligocene ; Park's 

 classification, Miocene.
