Nots.—I have used the term ‘“ Plutonic ” as being the most convenient I can 
at present use for purposes of classification. It is probable that the term 
‘“‘ Hydro-plutonic” might be better. 
I. Lower Patzxozorc, 
1. Silurian. 
(a) Rocks referable to this age are exposed over a large part of 
the district ; but the areas are not continuous, and the boundaries 
somewhat difficult to define shortly in words. Broadly viewed, a 
description may thus be given:—The largest area will be found 
between the Mitchell and Tambo rivers, north of the road from 
Bairnsdale to Bruthen. It includes almost all the drainage-areas 
of the Mitchell and Nicholson rivers and that of the west side of 
the Tambo River, south of a line drawn from Mount Balahead to 
the Fainting Range. The next area in size is found between the 
Snowy River, the boundary-line of the Colony, and the sea-coast. 
Outcrops are met with of various sizes, as at Bendoc, at Mount
