separation. In this coal field "the total thickness of the 

 whole of the Talchirs when best developed . . . cannot be 

 more than 300 feet. The greatest thickness of Boulder bed 

 is 22 feet, and vet we meet these beds all over the field." 



It will be remembered that Waagen places the Talchir 

 stage as the lowest of his three Permo-Carboniferous stages 

 succeeding the highest or Ardwick stage of the Carbon- 

 iferous proper ; the Karharbari is the Middle, and the 

 Artinsk the Upper stage of this Permo-Carboniferous group. 

 Griesbach (9) records a small patch of Carboniferous 

 rocks probably brought up by faults amidst the Mesozoic 

 beds of the Chitichun area, north-east of the Uttadhum 

 Pass. They have yielded many fossils including Fenestella, 

 Lithodendron, brachiopods of the families Terebratulidce, 

 Spiriferidce, and Productidce, some cephalopods and trilobites. 

 P. N. Bose (10) describes the Moulmein group of the 

 Tenasserim Valley. Here a limestone has furnished Lons- 

 daleia, Lithostrotion, Productus, etc., of Carboniferous age, 

 and on the supposition that this limestone belongs to the 

 Moulmein group, of which the writer has scarcely any doubt, 

 that group is Carboniferous. It contains worthless coals (the 

 younger workable coals of the area being probably tertiary). 

 T. D. La Touche (11) describes the Bhanganwalla 

 Coal-Field of the Salt Range, and gives a map and section 

 of the Coal-Field and adjoining district. Above the Salt- 

 crystal pseudomorph group (of Cambrian age) is a Boulder 

 bed succeeded by Coal-bearing beds. Above these are 

 tertiary (nummulitic) beds. 



There is one paper on the Carboniferous beds of Africa 

 (12). Some time ago J. Walther announced the discovery 

 of a Carboniferous Limestone in the Egypt-Arabian desert, 

 which was referred by him to the Lower Carboniferous, 

 In the lioht of further work the author refers these beds to 

 the Upper Carboniferous, and we are thus furnished with 

 1 new area for the marine Upper Carboniferous strata. 

 Amongst the fossils are Fusulinella, Enteles cegvptiacus, 

 and other species, Spirifer mosquensis, S. convolutus var., and 

 Dielasma hastatum. The beds seem most nearly related 

 to the Carnic Fusulina limestone and the corresponding 

 Gshelian division of Russia (stage of Chonetes uralica).
