The N. syncline shown in Fig. ii is very conspicuous at a point S. of the 

 village Bajocli. Here the Dhosa Oolite and the superjacent red Katrol 

 beds come to an end in the form of the end of a paper boat with steeply 

 inwardly- dipping sides ; and 200 yards from its upstanding curved end 

 rises a biggish cone of Katrol beds, just like the '' mast " of a paper boat — ^a 

 similar but much wider basin appears at the west end of the syncline. 



The D. O. along this syncline is very hard and tough : few Ammonites 

 have weathered out, but I have found what I believe to be Pelt, arduen- 

 nense, Per. rota, and As2}. bahecmum, all known to be natives of D. O. 

 seas. The Athleta beds are here covered up with debris : but an Athleta 

 fragment was found on its expected level. Fragments of Per. anceps 

 and Per. obtusicosta were picked up on the Anceps beds. 



So far I have described the outer shell of the Ellipse. Now for the- 

 kernel, which is interesting. The west end of the Ellipse shows the 

 subjacent beds best, for there I have found the best-preserved fossils. 



From under the ordinary Anceps beds, there emerges a great sheet 

 of hard brown Vanguard rock, running up to a crest. (Sub-Anceps 1): 

 next a mass of cold crimson shale, much like proper Anceps (Sub-Anceps 

 2) : below that another flat expanse of slab rock (Sub-Anceps 3), much 

 like Sub-Anceps 1. ; and below that nothing but weather-blackened cold 

 grey sandstone, in places impregnated with lime, to a considerable depth. 

 Sub-Anceps 1 is not a good fossil field : at the east end I have found some 

 small white Trigonice : also the large plate-shaped Congener ? or Para- 

 mor2)hus ? In the shales, Sub-Anceps 2, a long hunt only unearthed two 

 small broken Hmp. crassefalcatum (?). 



In Sub-Anceps 3 a fairly good crop was gathered : — fragments of Steph. 

 fissur.i ; Steph. ojjis ; PerispJi. Perdagatus, Bcdinensis and one like Congener ; 

 Naut. calloviensis ; and others that might be Perdagatus and Fissum 

 except for lobes. Now these finds show the similarity of these beds to 

 the highest Sub-Anceps beds at Keera : but there the rock is of light yellow- 

 brown : here it is of dark crimson-brown. Nearly all the specimens found 

 in these Sub-Anceps beds here have brothers in the Keera highest Sub- 

 Anceps or top-Macrocephalus beds. At the east end on a long transverse 

 ridge running up to the highest cone, these lower Sub-Anceps beds — there 

 of a coarse yellow-grey — contain worn fragments of what was not improba- 

 bly Per. altiplicatus, another Macrocephalus-bed fossil : and also a Bel. 

 sub-hastatus which. Waagen confines to Macrocephalus beds. 



Thus far down these Sub-Anceps beds here seem to agree with the outer 

 Macrocephalus ring of Keera. But here comes the rub. At Keera below 

 this outer ring, comes the inner, lowei-, ring of crowded molluscs and of 

 corals : then thick belts of golden oolite ; and then yellow and purple 

 shales, all stocked full of Ammonites, chiefly Stephanoceras . Here on the 

 other hand below the Sub-Anceps bed, we get nothing but the cold grey 

 weather-blackened sandstone, without the sign of a fossil. Black, grey 

 and grim these beds extend from east to west of the Ellipse, forming the 

 whole kernel of the range. They dip conformably, it seems, with the dip 

 of the shell, but I am not satisfied about this. The mass it is impossible 

 to describe without instruments. Roughly there seems to be a series 

 of concentric semi-circles, thrown out from the main backbone ridge 

 like onions with peeling layers, curving ridge separated from ridge by 

 deep hollows. Three such onions take up 2 miles. If the beds are 

 conformable with the beds of the shell, one would have looked for the 

 same beds as at Keera where conformity is clear ; whereas the actual 

 beds are so essentially dift'erent from the Keera ones. If they are 

 conformable, one must seek for the explanation of the difl^erence of the sub- 

 beds of this anticline from those of the parallel (15 miles north) anticline
