from the neighbourhood. At the same time there is a possibility that a 

 very small exposure of the cretaceous beds further east than any marked on 

 the map remains to be discovered. 



Three-fourths of a mile above Dussai, in a small stream tributary to 

 Cretaceous beds near *^^ Maan, cretaceous beds come in below the traps. 

 ^'^'^^- On the top of them are about 15 feet of purple 



and grey marls with limestone nodules. Beneath these is ' coralline lime- 

 stone^ apparently thinner than to the west. It contains near the base 

 a nodular and slightly ferruginous band, in which Hemiaster is foimd in 

 abundance^ together with Fecten ^-costatus and a few other fossils_, 

 mostly bivalve shells^ of which the Ostreida and Inocerami retain their 

 shells, while other forms appear as casts. In the coralline limestone 

 Bryozoa abound. Beneath these beds the top of a stratum of unfossili- 

 ferous nodular limestone is seen. 



Much fossil silicified wood occurs, which may, possibly, be derived 

 from the upper red marl with calcareous concretions, or from some sand- 

 stone, which, close by, at a village called Kirwan, overlies the red marl 

 and forms the top of the Bagh beds. This bed is considerably higher in 

 level than the others (all being horizontal or nearly so) which, in the 

 Dussai and two other small parallel valleys, just appear above ground near 

 the streams, while the sandstone caps the low intervening rises. It is 

 only seen over a small space near Kirwan. 



It is possible that this sandstone and the red marl represent some 

 peculiar red beds presently to be described, which are found near 

 Bulwarree. 



West of these small inliers the cretaceous rocks next appear about 



four miles further, in the valley of the Maan river

and its tributaries, where they occupy a consider- 

 able area, metamorphic rocks also being exposed. The Bagh beds appear 

 to be more richly fossiliferous in this tract than in any other spot where
