[Eead 8th June, 1899.] 



Some fossil marsupial remains from the classic locality of Lake 

 Colongulac having come into my hands, I sent the greater 

 number of them to Mr. De Vis for examination, and recently 

 received his report upon them. 



The bones were gathered by my brother, Mr. W. A. Hall, and 

 represent only a portion of those which I received from him, 

 those held back not being of any great importance. 



Lake Colongulac is one of the numerous shallow lakes which 

 occur in depressions on the basalt lava plains of "Western 

 Victoria. It is otherwise known as Lake Timboon, and lies 

 about a couple of miles north of the township of Camperdown. 

 The lake, it may be mentioned, is not to be confused with the 

 railway station, Timboon, which lies some 20 miles south of 

 Camperdown. Camperdown itself is situated just within the 

 southern borders of the great volcanic plain of Western Victoria. 

 The volcanic rocks extend about six miles further to the 

 southward, with a very irregular margin, while to the north 

 they reach some 40 or 50 miles, up to the flanks of the Dividing 

 Range. 



Eocene rocks of marine origin occupy the coast line 30 miles 

 south, and appear to underlie the whole of the intervening 

 country from there almost as far north as the volcanic rocks 

 extend, or at any rate as far as the base of the Dividing Range. 

 To the south they are exposed in numerous creek sections along 

 the Curdie and on the banks of the gi-eat crater lakes of Bullen-
