parent plates at tlie MacDonnell Eanges ; and Burr gives for 

 it (under tlie name of Mica) these additional localites : — Eiver 

 Gawler, Valley of the Nixon and Yankalilla. 



Lapis-lazuli. 

 I hare met with a specimen of this mineral (in the form of 

 veins in white granite), which was said to have been obtained 

 in the Murray Scrub — most probably from near Monarto. 



Albite. 

 This species occurs in veins in the metamorphic rocks exposed 

 in the Oolabidnie Creek near Franklin Harbour. It forms the 

 chief felspathic constituent of the granites of that district. 



Orthoclase. 

 "Well crystallized specimens occur at Angaston, and near 

 the Wallaroo Mine ; massive and crystalline at Angaston, 

 Ardrossan and "VVallaroo. Burr names the following localities : 

 — Barossa Eange and east of Mount Barker. 



T0URMALI]!fE 



Occurs at the Moonta and Paramatta Mines, at Mount Craw- 

 ford, Ardrossan and Angaston ; and Tate reports it at Mount 

 Boothby (90 miles north of Alice Springs), where it is said to 

 be abundant ; also at Barrow's Creek and in the neighbour- 

 hood of the Peake, Central Australia. Burr enumerates these 

 additional localities : — Valley of the Nixon, Barossa Eange, 

 Encounter Bay and Eapid Bay ; and the variety Rithellite also 

 in the valley of the Nixon. 



Cyanite. 



This mineral is to be found at Nuriootpa in quartz. Burr 

 mentions it as occurring in the colony, but does not give the 

 locality. Selwyn states that it occurs near Menge Town and 

 Mount Crawford. 



Topaz. 



In this colony the white Topaz appears to be the most com- 

 monly occurring variety of this species. It is found near 

 Blauchewater and elsewhere near Lake Eyre, Central Aus- 

 tralia. 



SILICATES {Hydrous). 

 Allophane 

 Occurs in the form of a blue deposit in the Miocene rocks of 

 the South-East (J. E. T. AVoods). 



Talc. 

 Tate reports the occurrence of this species on the flanks of 

 the Kaiserstuhl, and the var. Steatite at New Mecklenburg
