different character and somewhat different colour ; but the whole aspect 

 of the group is such that, were it not for the palseontological evidence, it 

 might pass for a portion of the palaeozoic rocks immediately below with 

 which it was classed by Dr. Fleming. The thickness of the formation is 

 very much less than that of the carboniferous beds, being on an average 

 a hundred and twenty to two hundred feet or sometimes even three 

 hundred feet.

jVo. 8. — The thin-bedded and flaggy sandstones with intensely red 

 shales or clays which form this group, have 

 been separated from the rest of the series, prin- 

 cipally on lithological grounds, and although the rocks differ widely in 

 appearance from the Ceratite-bearing triassic beds, I have been induced 

 Eeasons for supposing *« P^^ce them with or near the latter for the fol- 

 these beds Trias. lowing reasons : First, superposition shows them 



to form a newer sub-division than all the rocks up to the Magnesian 

 sandstone, inclusive. Secondly/, they thin out towards the sandstone No. 5, 

 which comes into the series near their termination but at a lower level 

 in the cliffs about Makrach. Thirdhj, they possess no similarity to the 

 carloniferous formation, nor yet to the associated triassic rocks, while 

 they have some analogies of colour with the succeeding porassic beds, 

 and if placed between the two latter might form a transitional group.* 

 It will be seen on reference to the diagram that this group No. 8 is 

 separated by a distance of nearly forty miles from both the known triassic 

 and Jurassic groups ; its position would correspond to that of an outlying 

 portion of either of these, or of the carboniferous, but the total absence 

 of fossils would seem to dissociate it from each. From above downwards 

 it comes into the place of the Jurassic beds, and the only characters left to 

 aid in fixing it are its red colour, unfossiliferous nature, and the presence 



* It was after discussion with Dr. Waagen that I was induced to classify this group 

 with the Trias. In the absence of palseontological evidence I was inclined to give it a 

 separate place by itself, but Dr. Waagen seemed to think there was sufficient probability to 

 warrant its being provisionally included as a part of the triassic group.
