94 HOLLAND AND TIPPER : INDIAN GEOLOGICAL TERMINOLOGY. 



Par series. — The lower of two divisions of the Gwalior system recog- 

 nised by C. A. Hacket (Rec., Geol. Sun., hid., Ill, 34, 1870). 

 Composed of quartzitic sandstone and shales resting without dis- 

 turbance on the eroded surface of the basement gneiss. Named 

 from a. village (26° 3' ; 78° 6') in the Gwalior State. 



Para limestone. — Named from the river Para in Eupshu by F. 

 Stoliczka {Mem., Geol. Surv., Ind., V, 62, 1866) and considered 

 to be Rhastic in age. Found later to include Upper Triassic 

 and Liassic beds, and abandoned as an unnecessary term by 

 H. H. Hayden (Mem., Geol. Surv., Ind., XXXVI, '87, 1904), 

 who used the terms Megalodon limestone for the rock (loc. tit., 

 84) on account of the prominent fossil found in it near 

 the base. The same formation has been referred to as the 

 Grey Limestone by A. von Krafft (Mem., Geol. Surv., Ind., 

 XXXII, 132, 1902) and C. Diener (Pal. Ind., Ser. XV, Vol. V, 

 pt. 3, 148 1908), a name already used in a stratigraphical sense 

 for a sub-division of the Nummulitic beds in Hazara (Middlemiss, 

 Mem.., Geol. Surv., Ind., XXVI, 39, 40, 1896). H. H. Hayden 

 afterwards proposed to use the name Para stage for the lower 

 part of the limestone formation containing Megalodon (Geog. 

 and Geol. of the Him., Part IV, 236, 1908), using the name Tag- 

 ling stage for the higher part of the formation and combining the 

 two under the name Kioto limestone. 



Parh limestone.— See Belemnite beds. 



Parihar beds.— Named by R. D. Oldham (Rec, Geol. Surv., Ind., 

 XIX, 158, 1886) from the Parihar hills, North- West of Jaisalmer. 

 The rocks lithologically resemble the Umia beds of Cutch, and 

 overlie the Bedesar beds which contain fossils similar to those 

 of the Katrol series. 



Patcham group. — Named from the island of Patcham in the Runn 

 of Cutch (Kachh) by F. Stoliczka (MS. report) for the lowermost 

 division of the Jurassic in that region. The rocks, consisting of 

 grey and yellcw limestones with sandstones and marls, have been 

 grouped as follows : — 



1. Light grey limestones and marls with Ofpelia serriger, corals 



and brachiopods. 



2. Yellow sandstones and limestones, with lamellibranchs, chiefly 



Tngonim, Corbulw, Cuculece, etc,
