sam (Loc. 37, H 5), the capital of the State of that name, where 

 the most abundant and varied fauna was found, is not far from 



the borders of the Northern States, 

 and after all the boundary is drawn 

 merely for administrative purposes, 

 and bears a very slight relation to 

 the physical configuration of the 

 country, much less to its geological 

 features. The third locality com- 

 prises the collections made by Mr. 

 Middlemiss during his traverse along 

 the cart-road east of Taunggyi, 

 introduced here for purposes of 

 comparison.

means so com- 

 plete as that described by Mr. 

 Middlemiss, but contains a richer 

 assemblage of fossils. It is situated 

 about a mile to the south-west of 

 the town, in the bed of the Nam- 

 Hen river, and about a quarter of 

 a mile above the bridge on the 

 cart-road leading to Mong Tung. 

 At the bridge, and for a short 

 distance above it, a series of red 

 sandstones and shales, with slightly 

 carbonaceous layers, is exposed on 

 the left bank, dipping generally in 

 a southerly direction, but greatly 

 contorted, especially towards the 

 upper end of the section. These 

 beds probably belong to the Meso- 

 zoic Namyau series. Immediately 

 to the south of these, and appa- 

 rently higher in the section, are 

 some limestones with obscure traces 

 of (?' Fusulina, but these may not
