GEOLOGY OF NEW ZEALAND. 
To the Editor. 
S1r,—I should like to make three corrections in the abstract of my 
paper on the Geology of New Zealand, which appeared in your last 
number. 
(1). On p. 442 I give Cape Rodney and the Kaipara as the most 
northerly localities at which the Pareora System has been found. I 
have lately seen, in the Canterbury Museum, a collection of fossils made 
by Mr. A. Reischek at Matakuhi, north of the Bay of Islands, which 
proves that the Pareora system exists in that locality. 
The following is a list of the fossils :—Stphonalia costata, Ancillaria 
hebera, Pleurotoma robusta, Natica suturalis, Turritella concava, Veneri- 
cardia Patagonica, Cucullea alta (?), and others not determined. 
(2). On p. 446 I say “In the North Island volcanic rocks, said to 
belong tv the Waipara System, occur on the east coast of Wellington at 
Red Island, south of Cape Kidnappers.” This statement was made on 
the authority of Mr. A. McKay, who says “ Red Island, which is 
situated two miles south of the Waimirima Bluff, is in reality a small 
peninsula, connected with the main land by a narrow ridge of beds No. 
3or 4, ,3. Contorted sandstones with Scalaria and Jnoceramus. 4. 
White siliceous rock, brecciated with green sands.] The so-called island 
itself is of igneous origin, and is in some parts crystalline in structure, 
and at others amygdaloidal ; it is green when freshly broken into but 
weathers brown or red. The shales and sandstones which underlie the 
igneous rocks at this point may belong to either No. 1 [Sandstone and 
shale with Jnoceramus| or 3, probably the latter. The strike is nearly 
K. and W., and the dip 8S.” (Reports Geol. Explorations, 1874-6, p. 
45). However, last January I was shewn, in the Napier Atheneum, a 
collection of rocks from Red Island, which were not igneous at all, but 
red jasperoid slates with manganese and sandstones, apparently belong- 
ing to the Rimutaka Series. There must be a mistake somewhere, and 
the question may be left open for the present.
