Hills, Thnaru, etc., (Jurors' Rep. N.Z. Ex., 1865, p. 257, and Trans. 

 N.Z. Inst., vol. xi„ p. 499), probably only in very small quantities as an 

 accessory mineral, or tbe rocks would necessarily become andesites, and as 

 large concretions in basaltic rocks of the Chatham Islands (Trans. N.Z. 

 Inst., vol. i., p. 180) ; by Mr. Buchanan, as fine specimens with serpentine 

 from the Awatere River (Geol. Rep., 1866-67, p. 35) ; by Mr. E. H. Davis, 

 at Dun Mountain (Geol. Rep., 1870-71, p. 112) ; and by Prof. Liversidge, 

 at Lake McKerrow, West Coast, Kakanui Mountains, Dun Mountain, and 

 Dunedin (Trans. N.Z. Inst., vol. x., p. 496), besides which there are some 

 fine specimens in the collection of the Colonial Museum from syenitic gneiss 

 of the Baton River, Nelson. 



Tremolite. — Some beautiful dendritic groups of tremolite, in quartzite, 

 from Kanieri, Hokitika, of a dark green colour, are in the collection of the 

 Colonial Museum, as well as some fine greenish-white radiating crystals 

 from Parapara, Collingwood, and some bright green radiating crystals from 

 the same locality. The occurrence of the mineral in Milford Sound is also 

 mentioned by Dr. Hector (Jurors' Rep. N.Z. Ex., 1865, pp. 267, 438). 



Actinolite. — The occurrence of this mineral in New Zealand is noted by 

 Dr. v. Haast in metamorphic schists of the West Coast (Jurors' Rep. N.Z. 

 Ex., 1865, p. 257) ; by Mr. Buchanan in the Awatere River (Geol. Rep., 

 1866-67, p. 35) ; and by myself as radiating fan-shaped crystals in the 

 river-beds of the West Coast south of Mt. Cook, where they are much 

 decomposed (Geol. Rep., 1874-76, p. 73). 



Anthophyllite. — Specimens of this mineral have been collected from the 

 Dun Mountain from time to time, the first specimens having been brought 

 by Mr. E. H. Davis in 1871. It occurs in a massive laminated form of a 

 leek-green colour, with a pearly lustre and a faint bronze hue on the 

 cleavage planes. 



Nephrite, R Si. — The occurrence of this mineral, commonly known as 

 " Maori greenstone," is mentioned by Dr. Hector (Jurors' Rep. N.Z. Ex., 

 1865, pp. 266, 412, 437) * from Milford Sound, and also as a single rolled 

 fragment, which had probably been carried there, from Silverstream, 

 Dunedin ; by Dr. v. Haast (Jurors' Rep. N.Z. Ex., 1865, p. 257) as rolled 

 pieces on the beach of the West Coast ; and by the late Mr. E. H. Davi 

 (Geol. Rep., 1870-71, p. 112) as white nephrite from Dun Mountain. The 

 only locality where it has been found in situ is at Milford Sound, where it 



* The first notice of this and the other Otago minerals is to be found in Dr. Hector's 

 reports on the geology of Otago, published in the Provincial Government Gazette for 

 1862-64, but these beiug now difficult of access, the reference (Jurors' Eep. N.Z. Ex., I860) 

 has been adopted throughout this paper, as in that publication Dr. Hector included a list 

 of all minerals which had been noted in his reports up to that date.
