28 HOLLAND AND TIPPER : INDIAN GEOLOGICAL TERMINOLOGY. 



Bijawar system.— Named by H. B. Medlicott (Mem., Geol. Surv., 

 hid., II, 6, 35, 1860) from the State of Bijawar in the Bundel- 

 kkand Agency, Central India. It consists of quartzites, some- 

 times conglomeratic, hornstone breccia, cherty limestone, fer- 

 ruginous sandstone, hematite-beds and contemporaneous trap- 

 flows. The rocks rest unconformably on the gneiss and are 

 generally not greatly disturbed ; they resemble the Gwalior series. 

 Rocks lithologically somewhat similar to typical Bijawars have 

 been described as such in the neighbourhood of Bagh and Jobat 

 (Mem., Geol. Surv., Ind., VI, 199, 1869), but they are foliated 

 with the gneisses and are probably equivalent to the Dharwars 

 of South India. C. A. Hacket (MS. Report, 1871, unpublished) 

 describes rocks of somewhat similar lithological characters, but close- 

 ly folded, in the Jubbulpore district. He divides the rocks in this 

 area into— 



i. Chanderdip group ,« ■■ 



3. Lora group. 



2. Bhitri group. 



1. Majhauli group. 



P. N. Bose {Rec, Geol. Sun., Ind., XXII, 216, 1889) regroups 

 these into— 



2. Lora group. 



1. Majhauli — Bhitri group. 



Bijori Stage.— Named by H. B. Medlicott (Mem., Geol. Surv., Ind., 

 X, 159, 1872) from the village of Bijori (22° 22' ; 78° 30') in the 

 Chhindwara district, Central Provinces. The Bijori stage or 

 horizon, as it was originally named, is the upper part of 

 the Damudas in the Satpura region, in which the remains 

 of Gondwanosaurus bijoriensis, Lyd., were found. The general 

 facies of the flora in the Bijori beds agrees with that of the 

 Raniganj stage in Bengal, whilst the overling Almod beds, 

 not distinctly defined, may represent the Panchets. 



Bivalve limestones.— One of W. Waagen's sub-divisions of the Cera- 

 tite beds (q. v.) of the Punjab Salt Range. 



Blaini (BHtli) beds.- — Boulder-beds and limestone occurring under 

 the Infra-Krol stage in the so-called " Carbonaceous " system 

 in the Simla Himalaya. The bonlder-beds have been con- 

 sidered to be of glacial origin, and have often been correlated with 

 the Talchir boulder-bcd and that of the Salt Range ; but
