KEN— KISTNA. 67 



Khongbll series.— Named by H. H. Hayden {Mem. Geol. Surv. 

 Ind., XXXVI, 141, 1907) from the Khongbu valley (27° 46' ; 89° 

 2') in Eastern Tibet. The rocks are unfossiliferous slates and 

 schists doubtfully correlated with the unfossiliferous Purana 

 rocks of the Outer Himalaya.

Kioto limestone.— Name appUed by H. H. Hayden (Geog. and 

 Geol. of the Him., Part IV, 236, 1908) to a great limestone for- 

 mation, over 2,000 feet thick, in the north-western Himalaya. 

 The upper part contains Jurassic fossils (Tagliug limestone of E. 

 Stobczka), while the lower part is Upper Triassic (Para limestone 

 of Stoliczka) ; but the intermediate part is mostly unfossihfer- 

 ous and forms a stratigraphical unit that cannot be sub-divided. 

 Named from Kioto (32° 26' ; 77° 58') in Spiti. Previously re- 

 ferred to as the " Grey Limestone " (A. von Krafffc, Mem. Geol. 

 Surv. Ind., XXXII, 132, 1902; C. Diener, Pal. Ind., Ser. XV, 

 Vol. V, No. 3, 148, 1908). 



Kirthar (Khirthar) series.— Named by W. T. Blanford {Rec. 

 Geol. Surv. Ind., IX, 9, 1876 ; Mem. Geol. Surv. Ind., XVII, 

 32, 45, 1880) from the Kirthar range, which divides Upper Sincl 

 from Kalat. Regarded by the author as Eocene in age. Blan- 

 ford included with the Kirthar, rocks corresponding to those dis- 

 tinguished by C. L. Griesbach {Mem. Geol. Surv. Ind., XVIII, 

 9, 1881) as the Alveolina limestone from the nature of the most 

 characteristic member. This formation, having been recognis- 

 ed in Sind also, was separated by F. Noetling (Centralblatt f. Min., 

 1903, 521 ; 1905, 135) as the Laki series {q. v.). The massive 

 white limestones of the Kirthar and Laki series in Sind are 

 sufficiently similar in appearance to cause confusion, but E. 

 Vredenburg {Rec. Geol. Surv. Ind., XXXIV, 89, 182, 1906) has 

 shown from the forammifera that, while the Laki is Lower 

 Lutetian in age, the Kirthar corresponds to the Middle and 

 Uppper Lutetian, with a stratigraphical break between the 

 two. 



Kistna series. — The uppermost series of the Cuddapah system. 

 Named by W. King {Mem. Geol. Surv. hid., VIII, 126, 1872),
