V. Chabazite. — Minute crystals of a zeolite, showing a typical 

 form of Chabazite. Twin rhombohedra, almost cubes, the twin 

 axis being the triad axis. In basalt from Lilydale. The 

 occurrence is similar to those at Malmsbury and Pentland Hills, 

 and Professor Ulrich's figures show similar rhombohedra modified 

 on the edges and twins of different aspect from Malmsbury. 



VI. Orthoclase. — In granite from a small outcrop south 

 of the State School, Addington. The crystal is a typical 

 simple crystal, showing prism, clinopinakoid, base and orthodome. 

 A marked difference of appearance is noticed in the faces of 

 different crystallographic forms. 



VII. — Schorl. — From the same locality. This is noticed on 

 the Learmonth Geological Map (Norman Taylor), but is not 

 mentioned in either of the above lists. 



VIII. A reputed Cinnabar specimen from Western Victoria. 

 This was obtained from Mr. H. S. Edgar (Pine Hills, near 

 Balmoral), and is stated to be the identical specimen referred to 

 as a rich mercurial ore in a report on that district in Progress 

 Report No. 9 of the- Geological Survey of Victoria. The circum- 

 stances (obtained from Aborigines and used by them for painting) 

 are the same. On examination it proves to consist essentially of 

 red lead and oil. 



NOTES ON THE SCARLET-BREASTED ROBIN. 

 By Robert Hall. 

 {Read before the Field Naturalists'' Club of Victoria, 14th January, 1901.) 

 Many portions of the life-history of the Scarlet-breasted Robin, 

 Petrceca leggii, Sharpe, are of much interest. Their dissociation 

 from the fellow species, the Flame-breasted Robin, P. phoenicea, 

 Gld., at one time, and the dissociation of their own sexes at 

 another, in addition to the nidification and their general bearing 

 to the young throughout the year, are such points. To towns- 

 people Robins generally make their appearance in the open 

 during April, but it is greatly a matter of the nature of the 

 season, as you may find them appear early in March (6/3/97, 

 Box Hill). Just such a March as we had last year brings them 

 to us, because it was so quickly followed by winter weather. 



The males of both species tune their lays upon their arrival in 

 the open. P. leggii comes out of the adjacent woods, but P. 

 phoenicea has travelled from the dense and quiet mountain tracts 

 to find the open. Though this is the rule I am well informed 

 that P. leggii will ascend near to the highest heights, such as 

 Kosciusko, 7,000 ft., or sometimes above it, and become com- 

 panionable with but another daring bird, the Pipit. I observed 

 both on the Dargo Plateau, 5,000 ft. above sea level, on 18th 

 February, 1895.
