horizons, and the Kund-ghat and Jabbi beds correspond to the 

 horizons CPc and CPg» of the Artinskian. This leaves the Ohidru 

 beds as possibly similar in age to the Lower Permian of Russia. 

 He draws attention to the great palseontologieal break between 

 the Chidru and Triassic beds of the Salt Range as a possible time 

 break in spite of litkological parallelism of the two formations. 



Productus shales of Spiti and Bashahr.— Term used by C. L. 

 Griesbach {Mem., Geol. Surv., hid., XXIII, 66, 1891) to replace 

 Stoliczka's term Ruling shales (q. v.). 



Prome beds— W. Theobald (Mem., Geol. Surv., hid., X, 270 , 1873) 

 described as Prome beds two stages in his Pegu system well 

 displayed in the Irrawaddy river bank opposite Prome (18° 43' ; 

 95° 15') in Burma. F. Noetling {Pal. hid., New Ser., I, 7, 1899) 

 divided the Pegu system into two series, attaching the Upper 

 Prome beds (Theobald's section B) to the Upper or Yenangy- 

 aungian and the Lower Prome beds (Theobald's section A) to the 

 Lower or Promeian series. M. Stuart (Rec, Geol. Surv., Ind., 

 XXXVIII, 261, 1910) objects to this scheme, and revives 

 Theobald's system. According to Stuart (loc. cit., 279) the Lower 

 Prome section of Theobald is Stampian and the Upper Prome 

 section, Aquitanian in age. The Prome beds are thus all regarded 

 as of Oligocene age, and are considered to be all below the 

 petroliferous beds of the Upper Burma oilfields. 



Pseudojadeite.— A. W. G. Bleeck (Zeit. prakt. Geol, XV, 353 : Rec, 

 Geol, Surv.. hid,, XXXVI, 267, 1908)=albite. 



Pseudomorphic salt crystal zone See Salt Pseudomorph stage. 



Pulivendla quartzites.— A local equivalent of the Nagari quart- 

 zites, named by W. King (Mem., Geol. Surv., Ind,, VIII, 168, 1872) 

 from the headquarters town of the taluk of that name (14° 25' ; 

 78° 17') in the Cuddapah district. 



Pulkoa schists See Semri series. 



Pullampet slates and limestones.— The upper stage of the 



Cheyair series of the Cuddapah system. Named by W. King 

 (Mem., Geol, Surv., hid,, VIII, 203, 1872) from the village of 

 Pullampet (Poolumpett ; 14° 8' ; 78° 16') in the Cuddapah 

 district. Also known by the name Tadputri slates and limestones. 

 Punjabian series or Stage.— Name used by F. Noetling (Neues Jahrb 

 f. Min., XIV, 424, 1901) to include the strata from the Boulder 

 bed to the Lavender clays of the Warcha stage in the Punjab 

 Salt Range. The whole series is regarded as about equivalent
