other cases, where the metamorphism has been less severe, it is easy to 
separate off from the Archaean complex the rocks corresponding to the 
sediments of this period, as in the Panch Mahals, Belgaum, Dharwar, 
North Kanara, Sandur, Mysore, Jabalpur, Singhbhum, and a part of 
Balaghat. The rocks thus separated from

the Arch8e?an complex were nrst known as 1 ran- 
sition rocks, being grouped under this name with the Bijawars 
and other rocks situated stratigraphically above the great Eparchsean 
interval. But they have since received local names in different parts 
of India. The area in which these rocks first received a local name is 
the Panch Mahals, where W. T. Blanford in 1869 ^ recognized that the 
rocks then classed as Transition or sub-metamorphic were in this area 
not the same as the Bijawars of Central India and the Central Pro- 
The Chanipaner vinces. He consequently proposed the name 
series. Chdmpdticr for these rocks after the ruined 
MusUm city of that name, situated on the edge of the outcrop of 
these rocks. In 1886 R. B. Foote proposed the name Dhdtwdr -

suspected that they bore any similarity as regards age to Blanford's 
Champaner group. 
In the south of India the manganese-bearing rocks of the following 
districts have been recognized as Dharwar in age : — Belgaum, Dharwar 
North Kanara, Goa, Bellary, Sandur, Chitaldrug, Shimoga, and Tumkur. 
In a work published in 18913, Dr. King expressed the opinion that the 
rocks of Chutia Nagpur, previously designated by the convenient term 
'Transition' are the equivalent of the Dharwars of Southern India. 
In 1904, whilst engaged in the examination of the manganese-ore 
deposits of the Jabalpur district, I came to the conclusion, as the 
result of a comparison of my specimens with those of other areas, and 
with the full concurrence of Messrs. Holland and Vredenburg, that the 
rocks of this area previously mapped as Bijawars are really of Dharwar 
age. Dr. Holland paid a special visit to this area to convince himself 
that the aspect of these rocks in the field supports the conclusion as 
to their age. When, in 1905, I visited the Champaner area, I was
