996 KING: KADAPAH AND KARNÜL FORMATIONS. 
truly conformable with the limestones in question, the two must stand in 
the same relation as the Jummulmudgoo and Banaganpilly beds of the 
KARNÜL series. The Juggiapett quartzite would then represent the 
Banaganpilly group of the Kurnool district, with which it agrees in the 
fact of its containing diamonds. 
The sequence of formations occurring in the neighbourhood of 
Juggiapett may be represented in the following order of superposition, 
descending :— 
7. Quartzite (No. 7) capping the Pulichinta Trigonometrical 
Station Hill. 
6. Chocolate slates (7.) 
5. Jatapalle quartzite bed (No. 6). 
4. Ginjupalli series, gritty quartzites (Nos. 2, 3, 4, 5), and slates 
or shales (b, c, d, e, J). 
3. Palnad limestones /! (Jummulmudgoos ?) 
2. Juggiapett shales or slates (a.) 
1. Juggiapett quartzite (No. 1), including a thin bed of dark- 
colored shales ( or slates) near its base. 
I make this division with considerable doubt, as the sections are not 
as clear as might be wished, while the presence of a considerable number 
of faults and the entire absence of any fossil remains render it im- 
possible to feel much certainty in assigning the different detached patches 
of quartzite, limestone or slate to distinct horizons. A large proportion 
of the slate areas is obscured by a thick layer of vein-quartz debris. 
The great extent and thickness of the jungle contributed greatly 
to the difficulty experienced in this matter; while the insufficiency of 
detail in the map, with occasional faultiness, in no way tended to the miti- 
gation of evils. In illustration of the structure of the area now under 
consideration, I have constructed seven sections, which will assist in 
explaining the rather complicated relations between the different parts
