flame (Col. Mus. and Lab. Rep., vi., p. 16). Specimens have also been 
i unde from the Buller River by Dr. Hector (Col. Mus. and Lab. Rep., 
ii., p. 26), and from the Wairau River, Nelson, by Mr. A. McKay (Col. 
Ms and Lab. Rep., xiij. +» P. 35). 
Garnets, R3. Si? + R Si, are of very common occurrence in New 
Zealand, associated with the crystalline rocks of the West Coast, and also 
with the quartz porphyries and pitchstones of Canterbury ; they are also 
frequently found in the auriferous washes of various localities, numerous 
specimens having been forwarded by diggers who have mistaken them for 
tinstone. They are mentioned by Dr. v. Hochstetter in mica schist at 
Collingwood, and in the gold-wash of the Takaka Valley (New Zealand, 
1868, Eng. ed., pp. 108, 107); by Dr. Hector, (manganese variety), in gneiss 
granite aud quartzite of the West Coast (Jurors’ Rep. N.Z. Ex., 1865 pp. 
266, 437), in the Kakanui River, as lime-iron garnets (Jurors’ Rep. N.Z. 
Ex., 1865, p. 437), in the gold-wash of Stewart Island (Trans. N.Z. Inst., 
vol. ii., p. 185), and in the gold-wash of the South (Trans. N.Z. Inst., vol. 
iL, p. 971); by Dr. v. Haast, as almandine in the quartz porphyries and 
pitchstones of the Malvern Hills and Mt. Somers (Jurors’ Rep. N.Z. Ex., 
1865, p. 257, and Geol. Rep., 1873-74, p. 9); by R. Daintree, Esq., F.G.8., 
in trachytic rocks and pitchstones of Snowy Peak Range (Trans., N.Z. Inst., 
. Vol. vii, p. 459, and by myself in gneiss and quartzose porphyry 
(granulite) at Resolution Island. Besides these garnets have been forwarded 
from Nelson by Mr. C. Broad, from Karaka Creek, Thames, by Mr. Davis, 
from Brighton, Wanganui, by Mr. Duigan, from Anatoki, by Dr. Hector, 
and from Mount Rangitoto, Westland, by Mr. E. Steward. There are, in 
the collection of the Colonial Museum, specimens of almandine, of a pinkish 
red colour, in granulite, from Dusky Sound ; of fine garnet sand, from the 
West Coast of Nelson, and of iron garnets in schist from Collingwood, in 
gneiss from Dusky Sound, and also in a quartz vein from the same locality, 
and as a garnet-rock from Otago. The prevailing crystalline form is the 
rhombic dodecahedron, but the icositetrahedron is also of frequent occur- 
rence in the speeimens from Dusky Sound. 
Muscovite, 8 “Al Si + K Sis , is of very frequent occurrence in New 
Zealand as a constituent of the mica schist, gneiss, and granite of the West 
Coast. Some fine plates occur at Charleston, and also in Mitre Peak, Mil- 
ford Sound. Its occurrence is mentioned by Dr. Hector in the schists and 
gneiss of the West Coast (Jurors’ Rep. N.Z. Ex., 1865, pp. 266, 437), and 
in a dyke granite on Great Barrier Island (Trans. N.Z. Inst., vol. ii., p. 
975); in the granites and schists of the West Coast, by Dr. v. Haast 
(Jurors' Rep. N.Z. Ex., 1865, p. 257; and as brown mica in a trachytic 
rock and silvery mica in a granitie rock at Snowy Peak Range, by R.
