tion of these three formations with their European equivalents 

 is a third and quite distinct question, and one far more difficult 

 to settle than either of the other two. Of these three coal-for- 

 mations the coalfields of Shag Point, Whangarei, and Waihao 

 may be taken as representatives. It still remains to ask, are 

 the Grey and BuUer coalfields the equivalents of either of 

 them ? This question is difficult to answer, because no marine 

 fauna of any extent is as yet known to be associated with the 

 coal-measures, an undescribed species of Cardlum, called 

 G. brurmeri, and an echinoderm called Klcinia disjuncta, 

 Hutton, being the only fossils known to me. The fossil 

 flora has been examined by Baron von Ettingshausen, who 

 pronounces it to be different from and older than that from 

 the Waipara and Shag Point, being, he thinks, of Cretaceous 

 age. On the other hand, the Oamaru series lies over these 

 coal-measures, probably unconfonnably, without the interven- 

 tion of any rocks with the Waipara fauna or flora. This is at 

 present the only evidence available, and, although the paliE- 

 ontological evidence is the more important, it is not sufficient 

 to form any decided opinion upon. 



In my opinion the New Zealand coalfields may be grouped 

 by age as follows : — 



4. Coalfields belonging to the Pareora series: (a) Mokau ; 

 (b) Waihao ; (c) Waitaki ; (d) Pomahaka ; (e) Dunstan (?) . 



3. Coalfields belonging to the Oamaru series : (a) Bay of 

 Islands ; (b) Whangarei ; (c) Drury and Lower Waikato ; 



(d) Nelson and jMotupipi ; (e) Kakahu ; (/) Green Island and 

 Saddle Hill ; (g) Tokomairiro and Kaitangata ; (h) Nightcaps, 

 Moreley Creek, and Linton ; (/) Orepuki. 



2. Coalfields belonging to the Waipara series : (a) Malvern 

 Hills ; (b) Mount Somers ; (c) Shag Point ; (d) Mount Hamil- 

 ton. 



1. Coalfields belonging to the Amuri series (?) : (a) Paka- 

 wau ; (6) Wangapeka ; (c) Westport ; (d) Greymouth ; 



(e) Eeefton.
