108 Tra?isactw?is. 



AuGiTE : Good crystals are obtained from weathered tufas at Otago Peninsula 

 and Banks Peninsula. 



^"Egibixe (5), (17) : Abundant in alkaline rocks at Dunedin. Also at Raro- 

 tonga, but of microscopic size only. 



Hornblende : Many varieties have been recorded in different petrographical 

 papers. The common green variety occurs widely in the diorites of the 

 south-west Sounds (16) ; brown or basaltic hornblende at Dunedin and 

 Banks Peninsula (5), (17) ; barkevicite (17) in alkaline rocks at Dunedin. 



RiEBECKiTE (30) : In granite boulders near Brunner, Westland ; also at 

 Campbell Island. 



Arfvedsonite (29) : Small crystals in trachyte of the Cass Peak, Port 

 Hills, Lyttelton. 



Tremolite : With garnet forming boulders in gravels at Lake Kanieri 

 and other Westland localities. 



Actinolite (22) : Abundant in West Coast schists and in Otago. 



^NiGMATiTE (Cossyritc) (17) : Quite abundant in phonolites and trachy- 

 dolerites at Dunedin. Also at Campbell Island. 



lOLiTE : Abundant in some contact rocks near Aorere River, west Nelson. 

 The form of crystal composed of trillings occurs in these rocks (P. Mar- 

 shall, this vol., p. 101). 



Nephelite (5), (17), (19), (26) : Abundant in large crystals in tinguaites, 

 basanites, and trachydolerites, Dunedin. Also in basanite at Auckland, 

 and in tinguaite boulders at Brunner (30). 



SoDALiTE (17), (19) : Small crystals in phonolites and trachydolerites, 

 Dunedin. 



Garnet (16), (18), (20), (21), (22) : Abundant in schist rocks, Otago and 

 Westland. A somewhat remarkable form in Otago, where a rock occurs 

 of a pink colour, containing a multitude of extremely minute crystals 

 of almandine. 



Grossulaeite (24) : Occurs with diallage in a garnet gabbro of the Dun 

 Mountain, Nelson. 



UvAROViTE (28) : Minute crystals at Dusky Sound. 



Chrysolite : Forms rock-masses of dunite at Milford Sound, as well as 

 the other localities mentioned by Hector. 



Melilite (17) : Plates in basanite at Puketiraki, near Dunedin. 



Zircon : Abundant in a porphyry at Campbell Island. 



Andalusite (20) : Relatively large crystals in schists. 



Chiastolite : Found by Mr. Isaacson in the north-west of Nelson (P. Mar- 

 shall, this vol., p. 101). 



Staurolite occurs with chiastolite (P. Marshall, this vol., p. 101). 



Sillimanite : With tourmaline in a specimen brought by Professor Black 

 from Stewart Island ; also in minute needles in a mica-schist from Dusky 

 Sound. 



ZoisiTE (18) : Occurs with epidote in schistose rocks in Westland. 



Epidote (17), (18) : Abundant in quartzite and schists, especially in West- 

 land. 



Tourmaline (19) : Large crystals at Richmond Hill, Parapara, in chlorite- 

 schist ; also in smaller groups of radiating crystals at the same locality. 



Analcite (17) : A rock-constituent, and in cavities in caraptonite, at Dun- 

 edin. 



M-OSCOViTE : Large crystals in granite between George Sound and Lake 

 Te Anau ; also widely distributed in minute flakes in schists in Otago 

 and Westland.
