SEC. 2.] EIJNN-ISLAND RANGE FROM PUTCHUM TO CHORAR. 103 



sands forming apparently the upper surfaces of the lateritie beds have 

 concretionary lumps and layers containing Tiirritella, small bivalves, and 

 fragments probably of EchinantJms (or some such depressed Echinoderm) 

 which fix the tertiary age of the rocks. Northward of this near Koorun, 

 and again east-north-east of Ruttria, the lateritie series (at the former 

 locality containing some shales) is overlaid by thick white and yellow 

 soft sands, also supposed to belong to the tertiary group, and sometimes 

 containing fantastic calcareous concretions. A patch of red rocks 

 occurs on the southern flanks of the Kala Doongur, not far from the 

 village of Dhorawar, nearly in the centre of the Putchum, suggesting 

 the possibility that the sub-tertiary group extended once throughout 

 the valley across the island.

 shells on the northern shore of the Putchum has

been already mentioned ; it is but a few feet thick, 

 and, if the fossils could be identified as recent, might bear testimony to 

 the former submerged condition of the Runn. If not recent, they are 

 probably very new tertiary. They are preserved only as casts.

KUEREER. 



The Kurreer Island shows a continuation of the northern Putchum 

 range, but completely isolated from it by the Runn. The same features 

 of ground, rising northwards in a long slope abruptly terminated by 

 clifis, again appear and the contorted zone at the northern foot of the 

 Kala range is represented by a broken anticlinal curve, its axis nearly 

 coinciding with the line of cliffs and its steep northerly inclinations 

 being occasionally seen.
