MISCELLANEOUS NOTES.

edges of all the successiou of beds from Tertiary through Trap, Cutch, 

 Upper and Lower Jurassics, down to the Bathonian, which emerge and 

 form the high hills of Putehum Island, 2-) miles north. If there is not 

 a fault, the long line of the north anticlines are followed by a broad and 

 gradual syncline, curving up to the north. 



I have remarked above that the Keera exposures range from Kimmeridge 

 to Lower CoUovian. There is some doubt about the Kimmeridge belt 

 being findable here. Dr. Waagen has in one place remarked that the 

 Dhosa oolite is the highest bed of the Charee group : yet in locating the 

 great Lytoceras rex found by Mr. Wynne on the south side of Keera, he 

 assigns it to a Katrol bed (p. 216), in a third place remarking that its bed 

 appears to be below Tithonian and above Oxfordian. No other fossils 

 having been sent to him from this bed, it was not so easy to specify the 

 horizon of the same. My reason for saying that Kimmeridge beds exist 

 here is a deduction from the above, for the Sequanian beds of Kantkot 

 (East Cutch) are not known to exist in this western half (p. 230). 1 

 didn't myself strike any Katrol (or Kimmeridge) beds, though it is not 

 improbable that they do appear to the south of Keera. To make things 

 clearer, it may not be out of place to give a list of the Cutch beds as far 

 as at present subdivided (refer to Vredenbiirg's Summary of the Geology 

 of India, 1910, p. 87, and to Waagen in Pal. Ind.)

If an expert were to spend a few months here, he would jjrobably be able 

 to subdivide the thicker belts of the above into several sub-zones, which 

 might be found to correspond with the latest-marked zones of European 

 Jurassics, e.fj,, there is the zone in which Waagen's Harp. i(/nobile and 

 crassefalcatum were found a zone of yellowish marl. Waagen places this 

 bed as Anceps or a little lower and yet not Macrocephalus. I believe a zone 

 between Anceps and yiacrocephalus has been recognized in Europe [Koenigi, 

 I think). Investigation might show this Keera bed (No. 6) to correspond 

 to this European bed. I found a Harpoceras very like to iynohile here. By 

 the way the Li/toceras which I found in this same bed prove to have the 

 sutures of adeloides.
