quantity. 
From Mr. James Scott, of Launceston, through the Survey De- 
partment, by order of the Governor, a quantity of semi-decomposed 
quartz, having drusy cavities filled with clay and loose crystals. It 
had been dug out from a depth of 13 feet from a lowround hill said 
to have a basis of slate, and situated a little north of Quamby’s 
Bluff, where excavations are carried on in search of auriferous 
beds. 
From Mr. W. F. Newman a very small quadrangular fish, 
having numerous spines with plates instead of scales, joined by

Several Australian species of Ostracion, more or less triangular and 
flattened, have been accurately figured by Richardson, from speci- 
mens sent home by Mr. Lempriere and others.
