THE VICTORIAN NATL' KALISI . 93 



l^ichylite occurs in a specimen from Betsy Cove. The glassy 

 magna has magnetite dust disseminated through it, and microlith 

 of felspar and augite are present. 



The basalts examined are from Cat's Ears, Howe Island, and 

 Greenland Harbour. The s[)ecimen from the latter place is very 

 rich in olivine; the augite and felspar are poorly represented, but 

 there is a good quantity of magnetite in the slide. The rocks 

 from Cat's Ears range from an augite basalt — poor in felspar, 

 with much glass — to a holocrystalline olivine basalt. No 

 instances of ophitic structure have been noticed. The specimen 

 from Howe Island is a very dense rock, almost opaque in thin 

 sections, from the dissemination through it of what is probably 

 magnetite dust. Augite and felspar are of limited occurrence. 



I'he phonolite occurs at Howe Island. In appearance it is a 

 fine-grained rock, studded with light-coloured porphyritic crystals 

 of felspar (sanidine). The rock has a fine-grained matrix ; the 

 nepheline occurs in sections of stout hexagonal prisms ; sanidine 

 frequently shows Carlsbad twining ; there is no plagioclase felspar 

 present. Among the other minerals of this rock are sphene 

 (titanite), mica, much altered hornblende, magnetite, and another 

 mineral which up to the present I have not succeeded in 

 identifying. 



The specimens of liornblende and i-orphyrite both come from 

 Cat's Ears. In addition to hornblende, triclinic felspar, sphene, 

 and magnetite occur. Trachyte also comes from Cat's Ears. 



A ground mass made up of small lath-shape fels[)ars and grains 

 of augite contains phenocrysts of sanidine. The small felspars 

 show marked fluxion structure. 



The other rocks to be noted are a volcanic ash from Cat's 

 Ears, containing fragmental felspar (mostly triclinic) and altered 

 augite and olivine, and a very dense, fine-grained specimen from 

 Royal Sound. It is almost opaque in thin sections. There is 

 no trace of felspar. A little augite, aiid possibly nepheline, are 

 present. 



A LIST OF THE BIRDS OF THE BIRCHIP DISTRICT. 



BV J. C. GOUDIE. 



(Head before the Fit-hl Xxfurali^ti' Cliih of Victoria, 10/// October, 18!tS.; 



It has been suggested to me that a list of the birds found in the 

 Birchip district would be of interest to ornithologists, as showing 

 the geographical distribution of the different species. Birchip 

 lies about 30 miles north of Donald, in long. 143 deg. east, lat. 

 36 deg. south, and is therefore situated on the " mallee fringe,'' or,
