15. Carboniferous Strata. 
Upon North Island: 
a) On the West-coast of the Prov. Auckland, South of the mouth of the 
Waikato River, sandstone, marl and shale with small coal-seams and 
fossil ferns: Polypodium Ifochstetteri Ung. , Asplenium palazopteris Ung. 
b) On the North side of the Harbour of Parengarenga, in the vicinity 
of the Harbour of Wangarei and on the Kawa-kawa- River, Pay of 
Islands. Mines very recently opened (Dr. Hector). 
Upon South Island: 
c) The Pakawau coal-field on Golden Bay, Prov. Nelson, with workable 
seams of very bituminous coal and indistinct fossil plants (Neuropteris, 
Equisctites , PJwenicites) in a coarse-grained sandstone. 
Under this head I will also mention the coal-fields on the West coast 
of the Prov. Nelson, examined by Dr. J. Huast: 
d) The Puller coalfield , on the Puller (Kawatiri) River, ten miles above its 
mouth , with seams 8 feet thick. 
e) The Grey coalfield, on the Grey (Mawhera) River, seven miles above its 
mouth, with beds 12 to 17 feet thick. Among the fossil plants Dr. Haast 
mentions: Zamites , Pecopteris, Equisetum and dicotyledon leaves. 
f) The existence of good bituminous coal in thin beds on Preservation Har- 
bour (Province Otago), upon Chalky Island, is mentioned by Clu Forbes 
(Quart. Journ. Vol. XI. p. 528). According to Dr. Hector this coal 
belongs to the same class as those found on Patterson s Point in Australia. 
4. Eruptive Formations of the Mesozoic Period. 
Upon South Island: 
a) The Serpentine dyke of Dun Mountain near Nelson, with lodes of copper- 
ore and chrome-ore, with Dunite (Olivine rock) and Diallage. 
b) The Syenite ot Wakapuaka and the Pyroxene porphyry of the Brook- 
Street Valley near Nelson. 
e) Felsite porphyry and Melaphyre of the Southern Alps (Prov. Canter- 
bury). Dr. Haast. 
d) The Hyperites of Mt. Torlesse, Prov. Canterbury. Dr. Haast. 
IV. Cainozoic (tertiary) Formations. 
1. Older tertiary Strata. 
A. Brown-coal-bearing, lower series. 
Upon North Island: 
a) The Hunua coalfield near Drury and Papakura, south of Auckland, 
discovered in 1858 by the Rev. Mr. Purchas, and worked since
