106 Transactions. 



are collected together, and additions are made of other species and locali- 

 ties known to the author but not hitherto mentioned in any publication. 



It is probable that the present list is still far from complete, but it will, 

 at any rate, serve as an index to the various discoveries that have been made 

 of late years, and may also be useful as a guide to those who may seek for 

 general information as to the occurrence of mineral species in the Dominion. 



The arrangement followed is that adopted in Dana's " System of 

 Mineralogy," 6th edition, 1906. 



SaLPHUR : Very good orthorhombic crystals at Rotokawa, near Lake Taupo. 



Zinc (3) : It appears somewhat doubtful whether this specimen was native 

 or was produced by artificial means. 



Gold : No important new discoveries have been made. Crystalline gold 

 has been recorded (8). Microscopic work has been done on some oc- 

 currences at Ohinemuri (2). 



Silver (4) : In addition, flattened grains of alluvial silver have been found 

 in some diggings in the Shotover River. 



Copper (9) : Crystallized copper of very recent deposition at Kawau Island. 



Lead (11) : The same occurrence as that mentioned in Hector's list. 



Platinum (18), (19) : The quantity of the mineral in these localities is small, 

 and is of no economic value. 



Meteoric Iron : An analysis of the Wairarapa meteorite mentioned in 

 Hector's list has been made by Mr. Donovan. 



Molybdenite : Large deposits in the Mount Radiant district, Karamea, 

 in lodes traversing granite country. 



Orpiment (23), (31). 



Realgar (23), (31). 



Petzite (1). 



Argentite (23). 



Galena (23) occurs in some quantity in the Jupiter and Pluvius Mines, 

 Te Aroha. 



Cinnabar (23) has been found at Waipori, Otago, but has not been mined 

 successfully. 



Pyrrhotite (28). Large quantities at the Champion Mine, Nelson. 



Chalcopyrite : The new discovery at Mount Radiant appears to be im- 

 portant. 



Pyrite : Good octahedral crystals are found in chlorite-schist at Parapara. 

 Cubes are common in phyllite near Mount Aurum, Utago. 



Nagyagite (]). 



Kermesite (23), (31). 



Pyrargyrite is said to occur at Puhipuhi, near Whangarei ; also 32. 



Tetrahedrite (1). 



Kerargyrite (23) : Several pounds' weight, from Waikoromiko Valley. 



Cotunnite (1). 



Quartz : The quartz of the Waihi Mine is sometimes platy in structure. 

 It is said to be pseudomorphous after barite. 



Precious Opal has been found in small quantity at Cabbage Bay. 



Hyalite : Incrustations are common on dolerite at Dunedin. 



Tridymite (7), (19), (26), (27) : Quite common, but in very minute aggre- 

 gates, in the rhyolites of the volcanic region of the North Island. 



Senarmontite (6) : Common at Mount Radiant. 



Molybdite : Not uncommon at Mount Radiant. 



Arsenolite (23), (31).
