78 HOLLAND AND TIPPER : INDIAN GEOLOGICAL TERMINOLOGY. 



included also (Aquitanian) and Nari (Stampian) beds by oversight 

 of a separating unconformity. 



Matldalay limestone.— Name instituted by F. Noetling (Rec. Geol- 

 Surv. Ind., XXIV, 104, 1891) for a series of unf ossiferous lime- 

 stones occurring near Mandalay (21° 59' ; 96° 8'). They were 

 considered by P. N. Datta (Director's General Eeport, 1899-1900) 

 as probably the same as his Tonbo limestone. T. H. D. La Touche 

 {Mem. Geol. Surv. Ind., XXXIX, 7, 1913) shows that this is a 

 mixed group, and the name is consequently discarded. 



Mandan group.— Name given by C. A. Hacket (Rec. Geol. Surv. 

 Ind., X, 85, 1877) to a division of his Aravalli system, and ori- 

 ginally regarded as above the Alwar series, but afterwards (Rec. 

 Geol. Surv. Ind., XIV, 281, 1881) regarded as equivalent to the 

 Raialo sub- division of the Alwars. 



Matldhali series.— Named by R. D- Oldham (Rec. Geol. Surv. Ind., 

 XVI, 196, 1883) from the village of Mandhali (30° 51' ; 78° 1') 

 north-east of Chakrata. Found to occur above the Deoban 

 limestones and afterwards correlated with the Blaini series of 

 Simla (R. D. Oldham, Rec. Geol. Surv. Ind. XXI, 137, 1888). 



Mangli beds.— Named by T. W. H. Hughes (Mem. Geol. Surv. Ind., 

 XIII, 71, 1872) (Manual Ed. 1, 129, 1879), after a small deserted 

 village (20° 22' ; 79° 4') about 50 miles south of Nagpur and 35 

 north-west of Chanda, near which Hislop found the remains of the 

 first Indian labyrinthodont (Brachyops latic&ps Owen). The 

 beds are very fine red and yellow sandstones with coarser grits 

 containing estherise and poorly preserved plant remains. They 

 are considered to be part of the lower Kamthis. 



Marine sandstone of Coromandel.— T. J. Newbold (Joum. Roy. 



As. Soc, XII, 86, 1850) uses this term as evidently equivalent 

 to his " Marine sandstone beds of Ramnad and Cape Comorin." 



Marine sandstone beds of Ramnad and Cape Comorin.— The 



occurrences of sandstone on the south-eastern coast of the Mad- 

 ras Presidency described by T. J. Newbold (Joum. Roy. As. Soc, 

 VIII, 243, 1844) are evidently those afterwards known more 

 widely distributed as the Cuddalore sandstones. Newbold says 

 that the fragmentary shell remains are species existing in the ad- 

 jacent sea ; and he regarded the beds as Tertiary like the laterite 

 and the Pondicherrv sandstone.
