CUDDAPAH— DANGOT. 39 



(Bee, Geol. Sun., Ind. XLI, 83, 1911-12) regards the two series as 

 of perfectly distinct ages, the Dagshai however being markedly 

 unconformable to the Subathu, and probably representing the 

 lower portion of the Murrees (q. v.). 

 Dalchipur sandstone.— Stage recognised by H. B. Medlicott (Mem., 

 Geol. Surv., Ind., II, 6, 1860) in his Semri (afterwards Lower 

 Vindhyan) series in Bundelkhand. From the town of Dalchi- 

 pur (24° 10'; 79° 5'). 



Baling series. — A series of schists and gneisses covering a large part 

 of the Darjeeling district and the Duars. Named by F. R. 

 Mallet {Mem., Geol. Surv., Ind., XI, 12, 1875) from Dalinkot (27° 

 1' ; 88° 46'). The beds appear to underlie and pass gradually 

 into the Darjeeling (Sikkim) gneissose granite ; they also appear 

 to overlie the Damuda and the Buxa series, but the apparent 

 position may be due to inversion. 



Oamdama quartzites and conglomerate.— A sub-division of the 



Alwar quartzite group, named by C. A. Hacket (Rec, Geol. Surv., 

 Ind., X, 86, 1877) from the village of Damdama (26° 54' ; 77° 

 19') in the Bharatpur State, Rajputana. 



Damuda series.— Named by T. Oldham (Journ., As. Soc. Beng., XXV, 

 253, 1856) from the river which runs through or near the great 

 Bengal coalfields in which the Damuda series is well developed 

 and includes the chief coal seams. See also W. T. and H. F. 

 Blanford, Mem., Geol. Surv., Ind., I, 46, 56 and 84 (1859), who 

 regarded these beds with the underlying Talchirs (loc. cit., p. 82) 

 as not more recent than Permian, though they had previously 

 been regarded as probably Jurassic. The term Lower Damuda 

 was used first by W. T. Blanford (Mem., Geol. Surv., hid., Ill, 

 29, 1861) for the stage subsecjuently named Barakar, but the 

 term " Upper Damuda " had been previously used in the Narbada 

 area for beds regarded as younger than the upper division 

 of the Damudas in Bengal. 



Dangot sandstones.— Name used by A. B. Wynne (Bee, Geol. Surv., 

 Ind., Vol. X, 120, 1877) for Siwalik rocks near Kalabagh, 

 considered equivalent to the Upper Siwaliks. W. Waagen (Geol. 

 Results : Salt Range, Pal. Ind., Ser. XIII, Vol. IV, 17) considers 

 them to be Middle Siwaliks. The name is from Dangot hill, 

 (32° 59' : 71° 40') near the Indus river, east-north-east of 

 Kalabagh in the Mianwali district.
