ALLAGIRI— ARAKAN. 17 



2. Badalgarh quartzite and shale. 



1. Nithahar quartzites and bedded traps. (Hacket, Rec, Geol. 

 Sure, hid., X, 86, 1877.) 



Amb beds — Name given by W. Waagen (Pal Ind., Ser. XIII, 

 Vol. IV, Part 2, 241, 1891) to the Lower Productus Limestone 

 of the Punjab Salt Eange. The village of Amb (32° 31' ; 

 71° 59') is about 6 miles N.N.W. of Warcha in the western 

 part of the range. For correlation, see Productus limestone. 



Amir shingle beds — Named by K. D. Oldham (jRec, Geol. Surv., Ind., 

 XIX, 160, 1886) after the village of Amir in the Jaisalmer State. 

 Sub-reeent shingle beds and possibly marine littoral deposits. 



Ammonite bed Of Kuchri (W. T. Blanford) afterwards included in 

 the Abur beds by R. D. Oldham. 



Anaram beds. — Plant-bearing shales. Casually mentioned by 

 W. King {Rec, Geol. Surv. Ind., X, 61, 1877) and supposed by 

 him to be equivalent to the Sironcha sandstones ; eventually in 

 a later paper (Rec., Geol. Surv., Ind., XIII, 15, 16, 1880) 

 considered to be locally bottom beds resting on the Kamthis and 

 lower in the Kota-Maleri group than the Kota zone of limestones. 

 Anaram (18° 54'; 80° 0') is a village in the Central Provinces. 



Anisoceras beds. — Name used by P. Kossmat (Rec, Geol. Surv., 

 Ind., XXX, 54, 1897) as equivalent to Valudayur (q.v.). 



Anthracolithic Sub=group.— W. Waagen (Pal. Ind., Ser. XIII, Vol. 

 IV, Part 2, 241, 1891) suggested the use of the term Anthra- 

 colithic to include the Carboniferous and Permian systems. 

 C. Diener has also used the term frequently in describing 

 Indian fossil collections, on account of the intimate stratigraphi- 

 cal and faunistic connection between these two systems in 

 the Indian region (Pal. Ind., Ser. XV, Vol. I, Part 2, 1, 

 1899, and numerous memoirs issued subsequently). 



Arakan system.— F. Noetling (Rec, Geol. Surv., Ind., XXVIII, 62, 

 1895; Pal, Ind., New Ser. I, 5, 1899-1900) used this term to 

 include the Pegu, Nummulitic (Bassein) and Axial (Chin) form- 

 ations in Burma. Having concluded that the Chin series is 

 probably not older than Cretaceous, the name Arakan covered 

 the period from Cretaceous to Upper Miocene (loc. cit., p. 14). 

 The Chin series (Axial group of W. Theobald) has since been 

 found to include Triassic and Upper Cretaceous fossils, and 

 is thus composite in character.
