VREDENBURGITE— YENANGYAUNG. 125 



Wer (Weir) quartzites.— The uppermost of five local sub-divisions 

 of the Alwar quartzites in the Biana hills, Eajputana. The 

 quartzites predominate, but the division includes some "' black 

 slaty shales," named by C. A. Hacket (Rec, Geol. Surv., Ind., X, 

 86, 1877) from the village of Wer (27° 1' ; 77° 14') near the Ban- 

 ganga river in Bharatpur State. 



Wetwin shales.— The name Wetwin series was used by P. N. Datta 

 (Director's General Beport for 1899-1900, 118) for some fossilifer- 

 ous beds regarded as probably Devonian near the village of Wet- 

 win or Wenwai (22° 6' ; 96° 39') in the Northern Shan States. 

 Examination of the fossils by F. B. Cowper Beed (Pal. Ind., New 

 Ser. II, Mem. 5, 157, 1908) shows certain affinities with the 

 Hamilton stage of North America and of Upper Devonian age, 

 but the precise age cannot be given (cf. Beed, Rec, Geol. Surv., 

 Ind., XL, 31, 1910). They are included by T. H. D. La Touche 

 (Mem., Geol. Sun:, Ind., Vol. XXXIX, 241, 1913) in the Plateau 

 limestone (Devonian section), and consist of very argillaceous, 

 yellowish buff-coloured shales occurring among the limestones. 

 This fauna has not been found elsewhere in Burma. 



Winchite. — Mineral named after H. J. Winch by L. L. Fermor 

 (Trans. Min. and Geol. Inst., Ind., I, 79, 1906). A blue mangani- 

 ferous amphibole found with the manganese-ore deposits of Kaj- 

 lidongri, Jhabua State, Central India. For full description see 

 Mem., Geol. Surv., Ind., XXXVII, 149, 1909. 



Yetiangyaung series or Stage.— Name proposed by F. Noetling 

 (Rec., Geol. Surv., Ind., XXVIII, 70, 1895, and Pal. Ind., New Ser. 

 I, 7, 1899) for the upper part of the Pegu system including the 

 Upper Prome, Kama beds and sandstones above the Kama beds 

 as described by W. Theobald (Mem., Geol. Surv., Ind., X, 

 268, 1873). The name is from that of the principal oilfield (20° 

 25'; 94° 56') in the Magwe district, Upper Burma. M. Stuart 

 (Rec, Geol. Surv., Ind., XXXVIII, 271, 1910) transfers the upper- 

 most sandstones to the Irrawaddy system, and regards the 

 petroliferous beds of the Yenangyaung and other oilfields as 

 equivalent to the Kama formations of the Prome district. He 

 consequently drops Noetling's term Yenangyaungian as un- 

 necessary. (See also Vredenburg and Stuart, Rec, Geol. Surv., 

 Ind., XXXVIII, 129, 1909.)
