Kahiku series: Quartz, clay-shales, sandstone, diorite slate, black 
cross-cleaved slate, siliceous and true clay-slate. 
Anau series: Porphyritic conglomerate, wacke, claystones, glossy 
slates and diabase, and porcellanitc. 
Oldest coal-formation in New Zealand in the eastern portions of the 
Southern Alps at the sources of the river Hinds, on Mount Harper, in the 
Malvern Hills, on the upper Ashburton River (Province Canterbury); the fossil 
plants, species of Glossopteris , indicate an age co-equal with the coal-fields 
of New Castle and Hunter River in New South Wales. (Dr. Haast.) See pag. 77. 
Eruptive rocks in dykes of long extent: diorite and diabase. 
III. Mesozoic (secondary) Formations. 
These I have arranged according to their probable age and the various 
localities as follows: 
1 Triassic group. 
Upon South Island. 
a) Maitai series in the Eastern ranges near Nelson; red and green clay- 
slates with highly inclined strata, and limestone at the base. (For 
example, on Wooded Peak, in Croix elles Harbour and Current Basin 
near Nelson.) As yet no fossils found. 
b) Richmond sandstone about Richmond not far from Nelson; a ferruginous 
sandstone with Monotis salinaria var. Richmondiana Zitt. filling whole 
banks., Halobia Lommeli Wissm., Mytilus problematieus Zitt., Spirigera 
Wreyi Suess; Astarte, Turbo etc., fossil woods ( Dammara fossilis Ung.) 
2. Jurassic group. 
Upon South Island: 
a) Waipara beds, clay-marl with fossil remains of Plesiosaurus Australis Owen. 
b) In the Amuri District (south-eastern portion of the Prov. Nelson) a com- 
plex of strata with saurian, fish and numerous shells (Dr. Haast). 
c) Shaw's Bay series at the mouth of the Clutha River in the Prov. Otago 
with Spirifer , Ammonites , shells resembling mytilus etc. (according to 
Dr. Lindsay). 
3. Cretaceous group. 
A. Strata containing Ammonites and Belemnites. 
Upon North Island: 
a) On Waikato Southhead inclined beds of gray marl and sandstone with 
Belemnites Aucklandicus v. Hauer, Aucella plicata Zitt. etc. 
b) On the Kawhia Harbour , similar beds with Belemnites Aucklandicus var. 
minor , Ammonites Novo-Seelandicus v. Hauer, Inoceramus Haasti Hochst. etc.
