species of the “ zones of Perisph. anceps and Pelt, athleta /” in the brown oolite are three 
species of the “ zone of Am. cordatus ” and one of the “ zone of St. mac.rocephalum.” In 
the ferruginous rock of Kuntkote there is one species common to the “ zones of Am. cor¬ 
datus and Pelt, transversarium and, lastly, in the coarse sandstone of the Katrol range 
are two species oi the Tithon-formation and one common to middle and upper Kimmer- 
idgian and Tithonian. 
If, therefore, the faunas have not in their development in India followed other laws 
than they did in Europe, we might arrange the deposits of the whole of the Kutch Jura in 
the following manner:

The most general division we could at present introduce into the Kutch Jurassic deposits 
is to separate them into two complex groups of sandstones, divided from each other by a 
zone of oolites of comparatively small thickness. 
But there remains yet the great question, what is Mr. Wynne’s “ Upper Jura of Kutch” 
which contains the plants, of which several are considered as identical with those of the 
Kajmahal hills, for all the beds which I have previously noticed, and which appear to 
represent the jurassic deposits of Europe from the Bathonian upwards to the Tithonian, 
compose only the “ Lower Jraa” of Mr. Wynne’s divisions, based on the physical relations 
of the beds. To answer this question satisfactorily in the present stage of our knowledge 
is impossible; we must be content to wait the result of further research into the fossils to 
be found in this interesting province. 
The Raigur and Hengir (Gangpur) Coal-field, by V. Ball, Geological Survey 
of India. 
The coal-field thus denominated has hitherto been generally spoken of as the ‘Gangpiir 
field.’ The result of my examination having been to show that the greater portion of the 
area is contained in the district of Raigur and the remainder in the sub-zemindari of Gang¬ 
pur known as Hengir (or Hittgir)—no portion of the coal-bearing rocks or their associates 
extending into Gangpur proper—it seems undesirable to perpetuate a misnomer which is only 
calculated to mislead. 
Whether this area is entirely detached from the TJ'dipur field or not I am at present 
unable definitely to affirm. My impression is, that a connection does exist towards the north- 
* The Lower Kimmeridgian is only represented by a single species, Asp. iphicerum. from N. of Dliosa out of a 
dark-red fine sandy ferruginous rock.
