114 HOLLAND AND TIPPER : INDIAN GEOLOGICAL TERMINOLOGY. 



amygdala of the Deccan Trap, which, as W. T. Blanford (Mem., 

 Geol. Surv., Ind., VI, 141, 1867) suggested, is merely stilbite 

 coloured by green earth as iu the case of hislopite (q.v). The name 

 is derived from Sahyadri, the name of the Western Ghats in the 

 Bombay Presidency, from the Khandesh district to Goa. 

 Tadpatri shales and limestones.— Named by W. King (Mem., Geol. 

 Surv., Ind., VIII, 181, 1872) from a town (14° 55' ; 78° 4') in the 

 Anantapur district. The upper part of the Cheyair series of the 

 Cuddapah system, also known as the Pullampet slates and 

 limestones. 

 Tagling limestone.— Named by F. Stoliczka (Mem., Geol. Surv., Ind., 

 V, 66, 1866) from the Tagling pass (32° 32' ; 78° 5') in Spiti. The 

 term was applied to a series of limestones 2,000 feet thick under- 

 lying the Spiti shales and regarded as Liassic in age. H. H. 

 Hayden has proposed (Mem., Geol. Surv., Ind., XXXVI, 87, 1904) 

 to drop the name as unnecessary ; the beds are of Middle and 

 Lower Liassic age, possibly including Rhsetic. More recently 

 Hayden (Geog. and Geol. of the Him., Part IV, 236, 1908) used the 

 term Tagling stage for the upper part of this great limestone 

 formation, and the name Kioto limestone to include it and the 

 Megalodon-he&ving portion below to which the name Para stage is 

 given. Cf. Grey Limestone. 

 Tal beds.— First recognised by H. B. Medlicott (Mem., Geol. Surv., 

 Ind., Ill, Part 2, 69, 1864) in the Lower Himalaya east of the 

 Ganges. Afterwards examined in greater detail by C. S. 

 Middlemiss (Rec, Geol. Surv., Ind., XVIII, 73, 1885) who 

 traced and mapped the beds over a large part of British 

 Garhwal (Rec, Geol. Surv., Ind., XX, 33, 1887 ; Mem., Geol. Surv., 

 Ind., XXIV, 63, 130, 1890). Only fragmentary, indeterminable 

 fossils have been found in these beds, which are doubtfully 

 regarded as Mesozoic on account of their position between 

 limestones of the Krol or Deoban type below and the Nummulitic 

 above. The beds have not been formally named, but are generally 

 known from the name of the valley (30° 0' ; 78° 19') in which they 

 were first found. 

 Talchir series.— Named by W. T. and H. F. Blanford and W. 

 Theobald (Mem., Geol. Surv., Ind., I, 46, 47 and 48, 1859) from 

 the state in Orissa, Bengal (Capital, Talcher, 20° 57' 20" ; 85° 16' 

 11"), where the rocks were first described in detail and separated 

 from the overlying Damuda series. Regarded originally as not
