SAKOLI— SHILLONG. 107 



intimately connected with the so-called Cambrian Magnesian 

 sandstone beds below. The name Bhaganwala group (stage) has 

 been proposed by F. Noetling for these beds (Rec, Geol. Surv., 

 Ind., XXVII 74, "80, 1894). 

 Sattivedll series. — Upper division of the Upper Gondwanas near 

 Madias, distinguished by R. B. Foote (Rec, Geol. Surv., Ind., 

 Ill, 14, 1870 ; Mem., Geol. Surv., Ind., X, 64, 1873), and named 

 from the hills about 35 miles north-west of Madras (13° 26' ; 80" 



Scythian Stage or series.— Name suggested for the Ceratite 

 formation of the Punjab Salt Range by F. Noetling (Nenes 

 Jahrb., XIV, 1901, 448). For sub-divisions, see Ceratite beds. 

 Sedaw limestone.— Name used by T. H. D. La Touche (Director's 

 General Report for 1899-1900, 81) for limestones near Sedaw 

 (21 c 53' ; 96° 18') at the western foot of the Shan Plateau. These 

 beds were included in the Mandalav limestone of F. Noetling 

 (Rec, Geol. Surv., Ind,, XXIV, 104, 1891), but La Touche 

 regarded the Sedaw limestone as distinct from the marbles of 

 Mandalav hill. The name was subsequently discarded in favour 

 of Plateau hmestone (q.v.). 

 Semri series. — Name, from the river Semri, proposed by H. B. 

 Medlicott (Mem., Geol, Surv., Ind., II, 6, 1860) as a provisional 

 term for the rocks in Bundelkhand, which he recognised as 

 similar to those previously referred to by him in the Son valley 

 as Sub-Kaimur. These rocks were known from about 1864 as 

 Lower Vindhyan, and were named Son series by E. Vredenburg 

 in 1906. Sub-divided locally by H. B. Medlicott into— 



5. Tirhowan limestones. 



4. Pulkoa schists. 



3. Dulchipore sandstones. 



2. Semri shales and limestone. 



1. Semri sandstone. 

 Sericitoid. — A mineralogical adjective used by L. L. Ferrnor (Mem., 

 Geol. Sun:, Ind,, XXXVII, 680, 335, 1909) as a field term 

 for describing phyllitic rocks in which the glistening mineral 

 looks like sericite, although subsequent chemical examination 

 may show the mineral to be some other species, such as talc. 

 Shillong series. — Briefly indicated in a preliminary paper by 

 H. B. Medlicott (Rec, Geol. Surv., hid,, II, 10, 1868) and after- 

 wards described in greater detail (Mem., Geol. Surv., Ind., VII,
