MILIOLITE— MUTH. 81 



Moulmein system.— This name was applied by T. Oldham (Sel. 

 Records Govt. Ind., X.. 33, 1856) to the reddish sandstones, marl 

 and associated massive limestone, conspicuously developed in 

 the neighbourhood of Moulmein (16° 30' ; 97° 38') and since re- 

 cognised throughout large areas of the Shan States. On account 

 of the fossils found in the limestone, the system was regarded as 

 Carboniferous in age ; but recent work in the Shan States has 

 indicated the existence of various Paleozoic strata from Silurian 

 to the Anthracolithic ProrfwiMs-bearing limestones, and it is pro- 

 bable that the rocks included in the Moulmein system during a 

 confessedly superficial reconnaissance are similarly varied in age. 

 See Plateau limestone. Maymyo limestone, Namhsim sandstones, 

 Naunghmgyi beds, Nyaungbaiv beds, Pyintha liemstone, Tonbo lime- 

 ■ stone, Wettvin series and Zebingyi series. 



Murree series. — Distinguished and mapped in the neighbourhood 

 of the well known hill station of Murree (33° 54' ; 73° 27') in the 

 Rawalpindi district, by A. B. Wynne (Rec, Geol. Sum., Ind., VII, 

 66, 1874). They were found to be resting in apparent conformity 

 on the Kuldanas which rested similarly on the Nummulitic lime- 

 stone series. In stratigraphical position they correspond to the Dag- 

 shai and Kasauli series of the Simla foot-hills, where the rocks are 

 also conspicuous purple shales and sandstones. This correlation 

 is confirmed by the occurrence of leaf impressions of Sabal major 

 Heer, in both areas (0. Feistmantel : Rec., Geol. Surv., Ind., XV, 

 51, 1882). The series has generally been regarded by the Geolo- 

 gical Survey as Oligocene and Lower Miocene in age. As G. E. 

 Pilgrim {Rec, Geol. Surv., Ind., XL, 187, 188, 1910) has shown 

 that the Kuldana beds, which underlie the Murrees, contain Bugti 

 vertebrates of Upper Acpiitanian age, the Murrees must be later, 

 possibly Burdigalian and Helvetian. 



Muscat series.— Name proposed by G. E. Pilgrim (Mem., Geol. Surv., 

 Ind., XXXIV, 7, 19, 1908) for beds of Laki (Lower Lute- 

 tian) age typically developed to the west and south-east of M\is- 

 cat (23° 39' ; 58° 35') consisting of pebble beds with interbedded 

 gypsiferous clays and ferruginous sandstones passing up into a 

 yellow, arenaceous limestone with Nummulites atacica, Assilina 

 granulosa, etc. 



Muth series.— Name used by E. Stoliczka {Mem., Geol. Surv., Ind., V, 

 21, 1866) from Muth (31° 57' ; 78° 6') in Spiti. Regarded by 

 Stoliczka as probably Silurian in age ; but R. D. Oldham suggested,
