Class Gastropoda. 

 Calyptraea calyptraeformis, Harris, p. 252. 

 Localities. — Orakei and Papakura, E. C. 

 Bange. — Upper Oamaru to Recent. 



Natica ovata, Harris, p. 259. 



In general outline and the shape of the umbilical opening 

 the specimens differ slightly, but only slightly, from those in 

 Auckland University College museum from the Miocene of 

 Trelissic basin. 



Locality. — Papakura, E. C. 



Range. — Oamaru to Wanganui. 



Turritella cavershamensis, Harris, p. 242. 



Localities.— Papakura, E. C. ; Arapaoa, Cox, 13, p. 33. 

 Bange. — Oamaru and Pareora. 



Vaginella aucklandica, sp. nov. Fig. 5. 



The shell is much more slender than V. depressa (Zittel 

 and Eastman, p. 489, fig. 1021). A groove running right 

 round the shell is usually the line along which breakage 

 takes place, and thus no specimen has been found with the 

 mouth uninjured. The one figured, however, shows some- 

 thing of this important part. Length of shell, 14mm.; great- 

 est breadth, 2 mm. 



Through the kindness of Professor Thomas I have seen a 

 copy of Tate's figure of V. eligmostoma in Trans. Eoy. Soc. 

 S. Aust., vol. ix., pi. xx., which differs considerably from any 

 specimen obtained from the Waitematas. 



Locality. — Orakei Bay, E. C. A Vaginella has been re- 

 ported by Hochstetter and many others from Orakei. Hoch- 

 stetter also found one at Papakura.

Pollicipes aucklandicus, Benham, Geol. Mag., March, 1903, 

 p. 110. 



Locality. — Motutapu Island. 



Bange. — This species is, so far, peculiar to Waitemata 

 beds. Has hitherto been called a Scalpellum. Mr. Chees- 

 man kindly called my attention to Professor Benham's paper, 

 which I had missed. 



III. Summary. 



Up to the present the palaeontological evidence as to the 

 age of the Papakura and Waitemata series is as follows : — 



(a.) Of the twenty-four species found in the Papakura 

 series, three are found elsewhere only in rocks of Oamaru
