limestones, which have yielded Jurassic fossils. See La Touche 

 {Mem., Geol. Surv., Ind., XXXIX, 304, 1912). 



Nandyal Shales. — The uppermost part of the Kundair stage of the 

 Kurnool series ; so named from the most important village in the 

 Kundair valley (15° 29' ; 78° 32') by W. King (Mem., Geol. Surv., 

 hid., VIII, 42, 1872). They are mostly purple in colour and 

 often calcareous, gradually passing into the underlying Koil-Kuntla 

 limestones. 



INapeng stage. — Name used by T. H. D. La Touche (Mem., Geol. Surv., 

 Ind., XXXIX, 284, 1913), for the Rhaetic beds developed capricious- 

 ly in patches at widely separated points over the Northern Shan 

 States. The beds consist principally of yellow, or variegated 

 highly argillaceous shales or indurated clays. Occasionally they are 

 impregnated with calcareous matter and pass into clunchy, sandy 

 marls or tough argillaceous thin-bedded limestones. The fos- 

 sils have been described by Miss M. Healey (Pal. Ind., New Ser., 

 Vol. II. Mem. No. 4), whose determination of their Rhsetic age 

 set at rest all the discussions caused by the survival of one or two 

 Palaeozoic forms. The principal fossils are Pterin, contorta, Gram- 

 matodon Lycetti, Gervillia prcecursor, Burmesia La Touchei, with 

 Myophoria, Pecten, Palceoneilo, Modiolopsis, and Conocardium. 

 Only three species are identical with European forms. Napeng 

 (22° 29' ; 97° 8') is the name of a small village, 9 miles east of 

 Pyaung-gaung Railway station. 



Narbada gravels. — Term applied to the older alluvial deposits of the 

 Narbada river. The fauna was partly studied by Dr. Falconer 

 and later by R. Lydekker (Pal. Ind., X, 111). 



Nari series.— Named by W. T. Blanford (Rec, Geol. Surv., Ind., IX, 

 9, 1876) from the Nari Nai, a stream which drains the hills to the 

 south of the Gaj in Sind, and the upper course of which lies al- 

 most entirely amongst the formations named from it. Correla- 

 ted originally by the author as lower miocene or upper eocene. 

 According to E. Vredenbm'g (Rec., Geol. Surv., Ind., XXXIV, 89, 

 1906) a portion of the beds of the complex Makran system are of 

 Nari age, while the Kojak series also includes the flysch facies 

 of the Nari in Baluchistan. The Lower Nari, mainly of lime- 

 stone in Sind, is regarded as Stampian in age, while the Upper Nari 

 shales and sandstones are regarded as Lower and Middle Aquit- 

 anian (Vredenburg ; loc. cit., 182, 267). The study of the 

 echinoids by P. M. Duncan and W. P. Sladen (Pal. Ind., Ser.
