XIV. Vol. I, 248, 270, 1884) had already indicated an Upper Oli- 

 gocene age. G. E. Pilgrim (Rec, Geol. Surv., hid., XXXVII, 140, 

 1908 ; XL. 187, 1910) found that some of the ossiferous beds 

 near the Sind-Baluchistan border had been grouped by mistake 

 with the younger Lower Siwaliks (L. Manchhars), and that these, 

 which are of Nari and Gaj age, are widely distributed over North- 

 West India. 



Narji limestones.— Named by W. King (Mem., Geol. Surv., Ind., 

 Mil, 70, 1872) from the village of Narji (Nerjee) in the Cuddapah 

 district (14° 39' ; 78° 35'). These limestones form the lower part 

 of the Jammalamadugu stage of the Kurnool series, and are typi- 

 cally fine-grained, grey, or buff-coloured limestones largely quar- 

 ried in the Cuddapah district for building purposes, and suitable 

 sometimes as lithographic stone. 



Naungkangyi beds. — Strata mapped in the Northern Shan States 

 and so named by T. H. D. La Touche (Director's General 

 Report for 1899-1900, 83) from a village (22° 4' ; 96° 30') to the 

 north of Mayniyo. The fossils indicate a general correspondence 

 with the Lower Ordovician of North-West Europe (F. R. Cowper 

 Eeed, Pal. Ind., New Ser., Vol. II, Mem. No. 3). Later this was 

 sub-divided [Mem., Geol. Surv., Ind., XXXIX, 67,84, 1913) into — 



(2) Upper Naungkangyi stage, which has a much wider distri- 

 bution at the surface than the lower beds. The strata 

 are peculiar argillaceous shales and claystones often 

 resembbng lithomarge in texture and of every variety 

 of colour. In all cases they show evidence of intense 

 crushing, resulting in a general distortion of the fossils. 

 Two lithological varieties can be distinguished, one 

 composing all the beds of this age west of Lashio of 

 the variegated type, and the second, the predominat- 

 ing type in the eastern range, consisting mainly of pur- 

 ple claystones. These latter have been distinguished 

 under the name of Hive-Mawng beds. The detailed 

 examination of fossils collected with due regard to strati- 

 graphy has not yet been completed. 



(1) The Lower Naungkangyi stage, consisting of yellow or buff 

 coloured sandy marls with strong lenticular bands of 

 coarsely crystalline limestone, all containing fossils. 

 There is very great variation in the lithological character 

 of the rocks at different localities. Particular fossils are,
