112 HOLLAND AND TIPPER: INDIAN GEOLOGICAL TERMINOLOGY. 



Sriperurabudur (Sripermatur) series.— Division of the Upper 



Gondwanas near Madras proposed by R. B. Foote (Rec, Geol. Surv., 

 Ind., Ill, 15, 1870 ; Mem., Geol. Sure, Ind., X, 65, 1873) from a 

 village (12° 59' ; 79° 57') 25 miles west-south-west of Madras city 

 in the Chingleput District. The Sriperumbudur beds are older 

 than the associated Sattevedus. • 



Srisailam quartzites.— The uppermost beds of the upper series of 

 the Cuddapah system, so named by W. King (Mem., Geol. Surv., 

 Ind., VIII, 252, 1872) from the sacred village of Srisailam, or 

 Sreeshalum (16° 5' ; 78° 53') on the Kistna river. 



Subathu series.— Named by H. B. Medlicott (Mem., Geol. Surv., Ind., 

 Ill, part 2, p. 11, 1864) from the hill station and cantonment of 

 Subathu (30° 58' ; 77° 2') in the Simla District, Punjab. Divided 

 into a Subathu stage at the bottom with Nummuhtes, overlaid 

 by Dagshai purple sandstones and red clays, and Kasauli grey and 

 purple sandstones. The name Subathu was subsequently reserved 

 for the lowest stage, the whole series being distinguished as the 

 Sirmur series (Man., Geol. Ind., 1st Ed., 524, 1879). The Num- 

 mulitics in the Subathu stage are similar to those of the Sind 

 Kirthar, that is of about Middle and Upper Lutetian age (E. 

 Vredenburg, Rec., Geol. Surv., Ind., XXXIV, 177, 1906). 



Sub=Himalayan system.— Term applied by H. B. Medlicott (Mem., 

 Geol. Surv., Ind., Ill, pt. 2, 10, 1864) to the belt of Tertiary rocks 

 forming the Siwaliks and other foot-hills in the Himalayan region 

 of the Punjab and United Provinces. The term is retained with 

 a general meaning, but is now superseded by more precise 

 chscrimination of the formations in the Sub-Himalaya. In 

 the first edition of the official Manual of the Geol. of Ind., 1879, 

 p. 524, the Sub-Himalayan system was divided as follows : — 



r Upper. 

 Siicalik series . . < Middle. 



(. Lower (Nahan). 



r Uppper (Kasauli). 

 Sirmur series . < Middle (Dagshai). 



C Lower (Subathu). 



Sllb=Kaimur series. — Name proposed by H. B. Medlicott (quoted by 

 T. Oldham, Joum. As. Soe., Beng., 253, 1856 ; Mem., Geol. Surv., 

 Ind., II, 303, 1860) for the rocks below the Kaimur series in the 

 Son valley. Similar rocks were described by H. B. Medlicott 

 (Mem., Geol. Surv., Ind., II, 6, I860) in Bundelkhand under the
