LATHI— MAHADEVA. 75 



the Kanawar system in Spiti. 'Composed chiefly of limestone 

 with Syringotlnjris cuspidata above and Atrypa aspera below. 

 Age, partly Devonian and partly Lower Carboniferous. Named 

 from the Lipak river in the valley of which near Lio (31° 53' ; 78° 

 39') the rocks are well exposed. 



Lituola beds. — Term used by E. Yredenburg (Ree. Geol. Surv- hid., 

 XXXVIII. 200, 1909) for the uppermost division of the Lower 

 Cretaceous beds in South Baluchistan. Named from the occur- 

 rence of the foraruiniferal genus Lituola. 



Lochambel beds. — The upper part of the Spiti shales include fossils of 

 Berriasian, Velanginian and Upper Tithonian age. The name was 

 introduced by C. Diener (Denk. k. Akad. Wiss. Wien., Math- 

 Naturw. Classe., Bd. LXII, 507, 1895). The ammonite 

 fauna is described by V. Uhlig (Pal. hid., Ser. XV, Vol. IV, fasc. 

 1, 2, and 3).

Magnesian sandstone beds.— Name used by A. Fleming (Journ. 

 As. Soc. Beng., 1853, 255) for a division of the beds in the Pun- 

 jab Salt Bange, which was found afterwards to be of Middle or Up- 

 per Cambrian age ; named also the Jutana stage (q. v.). The 

 rocks are sandy dolomites and light-coloured sandstones, with 

 oolitic or flaggy bands and shales. 



Mahabar schists.— Identified by H. B. Medlicott (Rec. Geol. Surv. 

 Ind., II, 12, 1869) and named from a hill-range in Behar (24° 

 35' ; 85° 55'). They are regarded as equivalent to the Rajgir 

 (Rajagriha) schists further north in the same area, and, accord- 

 ing to B. B. Mallet, are at a higher horizon than the Bhiaura 

 quartzites (cf. Rec. Geol. Surv. Ind., VII, 39, 1874), although con- 

 siderably metamorphosed in places. 



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

 XXV, 252, 1856) from the Mahadeva hills to the north-west of 

 Nagpur, where beds of this series were described by Hislop and 

 Hunter. When first separated from the Lower Gondwanas no 

 age was assigned to the Mahadevas in consequence of the absence 

 of fossils, but a conjecture was made, on account of their passing 

 up conformably into beds with fossil bones, as to their possible
