India — where an attempt has been made to separate from the oldest 
gneisses a system of limestones, schists, and quartzites. To this the name 
Ardvalli has been given, after the hills of that name to which the rocks 
of this formation give rise. It is probable that more than one series 
of rocks has been mapped imder this name, but the major portion of 
the Aravallis is probably equivalent to the Dharwars of Southern India. 
The term Arvali or Aravalli was first adopted ia 1877, by C. A. Hacket^ 
I have not had the advantage of visiting the typical Aravalli area, 
but have visited what must be an extension of this series in Jhabua 
State. My examination of the rocks found there in the vicinity of 
the manganese-ore deposit of Kajlidongri, and of specimens of this 
series from Rajputana, has shown me what a striking resemblance 
there is, both lithologically and. as far as I have seen, in mode of occur- 
rence in the field, between the rocks of the Aravalh system and those 
of the Chilpi Ghat series of the Balaghat district, and the more meta-

of the Central Provinces. And, as has been already explained, the 
Chilpis are to be regarded as the equivalents in the Central Provinces 
of the Dharwars of Southern India. Hence we are driven to the conclu- 
sion that the series that have received the following names, arranged 
in order of priority, are roughly contemporaneous: — Champaner (1869), 
AravalU (1877). Chilpi Ghat (1885), Dharwar (1886), and portions of the 
metamorphic and crystalline complex of the Nagpur-Balaghat area, 
Central Provinces. 
With regard to the question as to which term is to be adopted in 
' Champaner ' the preference to the others, it is obvious that according

be used. This, however, is the name that has been the least used of 
all, whilst that which has been extended to the largest number of areas, 
has passed into most general use, and is known best to geologists and 
'Dharwar' the most miners, is the term Dhdrivdr, the familiarity of the 
familiar term. name being largely due to the fact that the 
auriferous veins of Mysore are situated in the rocks to which this name 
was originally given. Since, however, the strict contemporaneity of 
these in various parts of India has not and never can be proved, partly 
because they are situated in isolated areas and partly because it does not 
seem probable that the sedimentation in the different areas can have
