sandstone, and a few thin sandy beds. They appear to be quite unfossili- 

 ferous. They have evidently the characters of the upper beds in the 

 Keem and Oomrawuttee rivers. 



The section extends down the left bank nearly to Dongra. Below 

 that village no more rock is met with on that side of the river, but close 

 to where the beds disappear on the left they come in on the right bank. 

 A section of rocks higher in the series is seen at Kurjun, and again at 

 Dholun and Pardee. 



The conglomerates at Kurjun contain but few and small agates, 



Section on right bank ^^^ they include large blocks of yellow and grey 

 urjun. sandstone, or sandy mudstone (indurated silt,) 



bored by Pholadidcs. These conglomerates contain bones (reptilian ?) 

 plates of tortoises, sharks' teeth of large size, and moUusca, principally 

 Gonus, Area, Pecten, and a Placwia closely resembling the recent 

 P. placenta,"^ No Nummulites were seen. The source of the sandstone 

 blocks is not clear ; they might be nummulitic. The fauna appears to 

 differ from that of the lower beds which contain Nummulites, The 

 rocks generally present some slight resemblances to those of Perim Island 

 in the Gulf of Cambay, as will be seen presently. 



The section in the Taptee ends near Pardee. The wide expanse of 



Country west of the country to the west of the nummulitic rocks 

 nummulitics. deserves little geological notice. It consists of 



alluvial clay, covered by cotton soil, and all its most important features have 

 already been described in the chapter devoted to the alluvium. Near 

 the coast are salt marshes, and along the shore sandhills. Rock is said 

 to occur near the surface in places, but in some cases at least, it appears 

 to be only calcareous conglomerate of apparently recent origin. 



Section 16. — Note on Perim Island. 

 In connexion with the examination of the tertiary beds of Broach 

 and Surat, a visit was made in February 1863 to Perim Island in the
