It is highly probable that the " sub-nummulitic " group of Cutch, 

 associated by Mr. Wynne with the underlying traps, is also represented 

 by the Ranikot beds, part of which closely resemble it in mineral cha- 

 racter. The traps of Cutch are much thicker than in Sind, and are doubt- 

 less equivalent not only to the thin bands in the latter province, but to a 

 considerable proportion of the associated upper cretaceous formations. 

 The identifications of the tertiary sub-divisions have been made by 

 Mr. Fedden, by whom the tertiary portion of Cutch was geologically 

 mapped. 



The series in Baluchistan is too poorly known for anything to be 



Tertiaries of Baluchis- adde<i to tne identifications already noticed be- 

 ^ n - tween the lower Khirthar beds, together with their 



associates west of the Khirthar range, and the rocks near Kelat, and 

 between the Manchhar and Makran groups. To the north of Sind the 

 rocks of the Bugti and Mari hills have been briefly described by 



Rocks of Suleman Captain Vicary 1 and a section across the Suleman 

 ran s e - range by Mr. Ball. 2 In both of these sections 



representatives of Manchhar and Khirthar beds are easily traced, but 

 neither Nari nor Gaj can be identified by description or fossils. 8 Mr. 

 Ball described beds which he considers of Sewalik age resting upon 

 sandstones and clays which he suggests may be Nahan. Both these 

 sub-divisions are clearly representatives of the Sind Manchhar group, and 

 the lower is described as resting upon nummulitic limestone (Khirthar) .

3 A few of the fossils mentioned by Mr. Ball, 1. c, p. 153, are Gaj forms, but the identi- 

 fication is very questionable. I examined the fossils, but could detect only Khirthar 

 species.
