been forced step by step to yield to the overwhelming pressure 
of other evidence, as well as in part to the evidence furnished 
by a better knowledge of the plants themselves, until in 1883, 
he assigned the Talchirs to the uppermost paleozoic, though 
this admission, it should be stated, was largely due to the fact 
of their presumable contemporaneity with the Australian 
glaciation. In order apparently to maintain his earlier con- 
clusions as to the greater part of the terranes of the Gond- 
wana system, he proposes, in the fourth and last volume of 
his " Fossil Flora," ^ to divide the system into three parts, in- 
stead of two by cutting off the greater part of the " Lower 
Gondwanas " to form a " middle " division. So unwarranted 
seems such a division that the late director of the Indian 
survey deemed it expedient to criticise it officially ; and in a 
notice which was published with the last part of the 
same volume. Dr. Medlicott says (p. 5) : "Having let down his 
lower Gondwana division into the paleozoic era, the chief 
effort of Dr. Feistmantel's present contention clearly is to ex- 
tend that division so as to force up the Damuda (as defined 
by him) ; and forced it accordingly is. His main divisional 
boundary, which on page xxiii is said to be sufficiently 
marked, is placed where no one has yet been able to draw a 
boundary in the field, within the Barakar measures, one of 
the most homogeneous of the hitherto accepted stages of the 
Damuda Group." However, Dr. Feistmantel still adheres to his 
late divisions of the system, though in his two contributions ^ 
to the general subject, published since then, his correlations 
of the various horizons are, in the main, much more har- 
monious with those of the other paleontologists and geolo- 
gists of India. 
Primarily, for the sake of giving what may fairly represent 
the most recent conclusions on the paleobotanical side of the 
matter, as reached while considering also the animal remains, 
and, secondarily, to present compactly and graphically some of
