MISCELLANEOUS NOTES. 1349 



One peculiar feature of the ground is the curve which indents the North 

 side. There are several low parallel walls — the outcrops of the harder 

 Ammonite strata — running along the North edge ; but they curve at right 

 angles at this point: each of them — as do also the sandstone beds to the 

 North. There was a bad kink in the fault here. 



We must then suppose that at one time the whole stadium was a vast 

 hill; all its centre has been eroded, and has probably become much more 

 so in the last 31 years: anyhow a very low ridge is marked in the Trig- 

 ometrical Survey Map which certainly doesn't deserve a contour line, 

 now but then other hills deserve a contour line, which do not get it. 



Basalt heaved up the West end : basalt heaved up the East end. Now 

 the hills of the East end are of crimson-black rock, weathering on their 

 inner faces into light yellow grit, while their broad slabby backs remain 

 black and grim as contrasted with the golden yellow of the main stadium. 

 They are of lower, earlier, deposit : and I presume Dr. Waagen refers to 

 these when he writes of the Anceps beds of Samatra. I found two or 

 three Anceps among them and several other Interrupti Perisphinctes, which 

 I could not name. They also contain many biggish flat broad-trimmed 

 Ammonites for which I can get no satisfactory name from the list of those 

 supplied to Dr. Waagen. 



The lowest beds visible in the lowest part of the hollow of the Eastern 

 clump of hills seem to be of a dirty white sandstone — beds lying almost 

 level — with, it seems, no fossils. Above them belemnite bearing rocks 

 appear: these also contain very big Rhynchonellcs . At one spot on the 

 outer edge of these black rocks there is a whole swarm of these big 

 Rhynchonellce. Embedded in the black rocks on the slabby side can 

 be seen many big specimens, much worn and inextricable. One looked to 

 be a long ribbed Stephanoceras. Another specimen was a big Aspidoceras 

 (as far as I could judge). Its upper surface was worn almost flat and 

 squat with the rock : I barely noticed it : but I did and I set to work 

 carefully and long. As I removed the surrounding matter, it broke up. 

 On unearthing a big outer fragment, I found strong straight even ribs, 

 which from its shape and volution pointed to an Aspidoceras. It was 

 22 inches across and I much lamented its loss. 



A big Rehmanni\ was also found not far off. Above the black rock comes 

 the golden yellow, which I consider to be athlete beds for in the lower 

 parts of the deposit I found many athlete fragments. There were also 

 large numbers of Perisphinctes rota many Per. dhosaensis, great numbers of 

 fragments of Stephanoceras opis (at least I can see no other Stephanoceras 

 in Waagen's book to which these fragments answer) : unfortunately I 

 found no specimen with inner whirls : Stephanoceras polypheynus, tumidum, 

 and diadematum, Per. curvicosta, angigaster, and Indogermanus and
