for 1902-1903, 20) to be equivalent to the Bagli (Upper Cretace- 

 ous) beds. 



Minniyur beds. — The uppermost beds of the Cretaceous forma- 

 tion in the Trichinopoly district, included by H. F. Blanford in 

 his Ariyalur (Arrialoor) group (Mem., Geol. Surv., Ind., IV, 141, 

 1862). Named from a village (11° 16' ; 79° 13') in the Trichino- 

 poly district. The fossils are mainly of Danian facies, and thus 

 the beds have been separated as a higher stage from the Ariyalur 

 (Upper Senonian) stage (H. Leveille, Bull. Soc. Geol. Fr., 3rd 

 ser-., XVIII, 144, 1888, and F. Kossmat, Rec, Geol. Surv., Ind., 

 XXX, 1897, 67, 68, 81). The Ninniyur beds of the Trichino- 

 poly area correspond to the Nerinea beds of the Pondicherry area. 

 E. Vredenburg (Rec, Geol. Surv., Ind., XXXVI, 195, 211,' 1908) 

 points out that these beds are, in part at least, equivalent to the 

 Cardita Beaumonti beds and Pab sandstones of the Baluchistan 

 area, while the Orbitoides and Cerithia indicate a Msestrichtian 

 age for a portion of the Ninniyur beds. 



Nithahar quartzites and bedded trap.— The lowest of five local 



sub-divisions of the Alwar quartzite group. Named by C. A. Hacket 

 (Rec,, Geol. Surv., Ind,, X, 86, 1877) from a village (26° 58' ; 77° 

 4') in the Alwar State, Rajputana. 



Niti limestone. — F. Noetling uses this term (Lethea geognostica, Ilnd 

 Theil, Das Mesozoicum, Bd., 1, Trias, 1905, 140) for the beds at 

 the base of the Muschelkalk in the Spiti and Kumaun Himalaya. 

 The Niti pass (30° 58' ; 79° 53') is in the Kumaun Himalaya. 

 For these beds the term Nodular Limestone was previously used 

 by H. H. Hayden in Spiti (Mem., Geol. Surv., Ind., XXXVI, 

 67, 1904). C. Diener uses the term in the sense of Noetling through- 

 out his memoir on the Trias of the Himalaya (Mem,, Geol. Surv., 

 Ind,, XXXVI, pt. 3, 1912). 



Nodular limestone.— Name used by P. N. Bose (Mem,, Geol. Surv., 

 Ind,, XXI, 2, 36, 1884) for the lowest of his three sub-divisions 

 of the marine Cretaceous formations of Bagh (q. v.). He regarded 

 the formation as of the same age as the Gault and the South Indian 

 Utatur stage, but the evidence was admittedly imperfect. 



The term Nodular Limestone has also been used in a definite stra- 

 tigraphical sense by H. H. Hayden (Mem., Geol. Surv., Ind., XXXVI, 

 67, 1904) for some beds at the junction of the Lower Trias and 

 Muschelkalk in the Spiti Himalaya. Cf. Niti limestone.
