The preceding forms pass into one, which in the young state closely approaches the 
type, save that it is a stouter shell. 
There is, moreover, no fixity as regards the sculpture on the valves, so far as the extent 
covered by it, still the general facies is that of the type, which, according to Mr. Blanford, 
would seem more common in Southern India than in the Gangetic* basin, A fossil specimen

Note on the Baeakabs (coal-measubes) in the Beddadanole Field, Godavari 
District, by William King, b. a., Deputy Superintendent, Geological Survey 
of India . 
The question as to the existence of coal in the Godavari District, and indeed in the 
Madras Presidency—for the area under consideration is the only known one of coal-hearing 
rocks in the British territory to the south of the Godavari river—is still as full of obscurity 
as it was when I drew attention to the Beddadanole field last year. I have had, during 
this season, another opportunity of examining the ground most closely, but without success; 
and this search was so close that it does not seem possible that any outcrop of coal will 
ever he found by surface searching. Any further exploration must, therefore, be made by 
boring, and I am not without hope that coal may then be found. 
2. The most important point, aud in fact the only tangible one to ho relied on, is that 
the rocks of the Beddadanole area are Bardhars ; that is, they belong to the lower member 
of the Damuda Semes, or the coal-bearing rocks of India. It is true that no seam of 
coal is visible, hut this does not at all necessarily imply the non-existence of coal. 
3. To try and show that coal may exist in this field, I shall compare it with other 
adjacent fields, viz., that to the north-west, on the Godavari below Badrachellmn; and the 
Singareny coal-field to the westward, in the Nizam’s dominions. In the first of these, 
though it was reported by Colonel Haig to Mr. W. T. Blanford that coal was said to have 
been found down there, no coal was to be found at the place; indeed, the borings afterwards 
put down would seem to show that coal could not occur at the surface. At kny rate, the 
rocks were seen to be JJaMUDas ; and borings revealed seams of coal. These are, however, 
not of much extent on the British side of the river, though they are probably large 
enough on the Nizam’s side, as I have since found that an outcrop of possibly the same 
beds shows at some twenty-five miles to the south-west. 
4. As regards the Singareny coal-field, I can compare it more closely with that of Bed¬ 
dadanole, having likewise again visited it this season, when it is now being thoroughly ex¬ 
amined by Mr. Heenan, the Superintendent in charge of the Nizam’s coal-fields. The only 
difference of outward circumstances, as regards the present enquiry, between this and the 
Beddadanole field is, that coal did show at the surface in the former, though only in the 
most fortuitous way. Otherwise, the series of rooks ( Bardkars) in each field are identical 
* For the information of Naturalists at home, I may as well add that the Narbada does not belong to the 
Gangetic basin,
