to the lower beds of the Cretaceo-Tertiar}' series f. It remains, 

 therefore, that the unconformity must be placed either below the 

 limestones and calcareous greensands altogether, or — where I incline 

 to put it — between the upper and lower parts of this division." 

 Accordingly in his section he shows No. 3 quite unconformable to 

 No. 4. 



I have given Mr. McKay's argument as fairly as I can ; but it will 

 be unnecessary to criticise it, although it is favourably noticed by 

 Dr. Hector {I. c. p. xvii). I have mentioned it to show how slight 

 is the foundation for introducing an unconformity into this section, 

 which is published by the Survey, and reproduced by Dr. Hector in 

 his Progress Report. As the fossiliferous bed, No. 3, is allowed by 

 Mr. M*=Kay and by Dr. Hector (' Geological Reports,' 1883-4, p. xiii) 

 to belong to the Oamaru series, it does not matter for my present 

 argument what age the underlying beds are supposed to be of. My 

 object is to attempt to correlate bed No. 3 with other rocks in 

 Canterbury and Otago. Through the kindness of Dr. von Haast, I 

 have been allowed to examine all the Tertiary New Zealand fossUs 

 in the Canterbury Museum, and consequently T am in a position to 

 make a more complete list of the Curiosity-Shop fossils than has 

 hitherto been given, and to add several species to the list from the 

 Weka-pass stone. Dr. Hector has also allowed me to examine the 

 Ototara fossils in the Wellington Museum, so that I can now give a 

 tolerably correct list of them also.

These specimens have been determined by Dr. Hector (Geol. 

 Reports, 1879-80, p. xvi); also found in the Ototara building- 

 stone ; at Brighton on the west coast ; and at the horizon of the 

 Weka-pass stone at Amuri Bluff.

Reported by Mr. M'^Kay. I have seen no specimens. This 

 species is still living, and extends through the Wanganui and
