Fossil shells of the genera Osfrea and Pecten, along with Foraminifera, were met with in 

 the interior parts of the Southern Yomah between Wanet, Wachoung and Kenbatee. At the 

 fonner place, on the watershed between the headwaters of the Pazwoondoung and Kenbatee 

 choungs, at a considerable elevation, say about 700 or 800 feet, in large blocks similar to 

 reefs, they are much weathered out. In a choung on the Kenbatee side, called Kayoo choung, 

 which is passed in crossing from Wachoung to Kenbatee, fossils are etill more numerous, 

 the fossiliferous rocks covering, as it were, the whole bed of the choung. There are 

 several Kayoo choungs in the Yomah, for instance one in Upper Zamayee, which might sug- 

 gest a similar occurrence of fossils. 



This sandstone forms a most intricate labyrinth of low ridges, diverging from a main 

 chain and branching usually almost at right angles, and rendered still wilder by the many 

 ravines and gorges, that are formed by the heavy rains during the south-west monsoon. All 

 these spurs and ridges are, as a rule, steep, often so much so (especially along the main range) 

 that it becomes sometimes very difficult to ascend them, comparatively low as they may be.

Very curious is the regular occurrence of the rounded small knolls, that appear so fre- 

 quently on the ridges, especially where other ridges branch off. These cause tiresome ups 

 and downs in marching along ridges otherwise level and easy. The main range itself, of about 

 1,000 to 1,500 feet elevation, runs in general from north to south with a little westing. To- 

 wards the north it winds much, attaining an elevation of 2,000 to 2,-500 feet. 



The soft sandstone is of a very permeable nature, and bears, as a rule, a very rank vege- 

 tation, although the ground is rather poor in herbs and shrubs, and still more so on the higher 

 and steeper ridges. 



This whole seft sandstone formation is covered by a very uniform and usually lofty for- 

 est, tiz., the upper mixed forest But in the moister valleys, especially along the Sittan"' 

 side, evergreen tropical forests are frequent, while on the exposed crests of the highest parts 

 of Kambala toung, &c., upperdry forests for the first time make their appearance.
