nor cau I see in Waageii's work any other similar fossil. Several pretty 

 little Phi/lloceras (disjmtabile, I believe) were found together with fragments 

 of large specimens of the same. Not a few fragments of a Lytoceras are 

 there, but unfortunately only very broken fragments, none with sutures 

 visible, fell in my way. One fine big Rehmanni (?) had his top edge 

 showing : a patient excavation brought it up to the surface, in 9 bits : but 

 it makes a fine show now that it is patched together. Its 15 inches 

 diameter have sutures to the end. 



No. 7. The hard rock of this ridge is a mixture of brown, crimson and 

 yellow, much like the facies of Dhosa oolite : but the beds lying outside 

 No. 6 on the east and south sides are of soft dark crimson stufl:'. Some 

 Omphalodes and fragments of others like those found in Fakirwadi Ance2)x 

 beds join these lower beds on to the Charwar Series. On the south-east 

 side, where the Anceps beds are worn down to a flat broad plain, you 

 will find quite a good number of Ance2)s, several fairly complete and plenty 

 of fragments. Pseudorion (?) I also found in the beds on the south. One 

 specimen like an Anceps of some 2>\" diam., has spines only on the inner 

 whorls : none on the body chamber. 



No. 8 seems to be of Dhosa oolite : its facies appears like that of the 

 Charwar D. O. : and a few specimens of Peruphinctes rota (?) add to the 

 probability, on its inner face [on the N. side of the hill.] Here is a thin 

 belt of white stone, just as in places along Charwar : and a small fragment 

 of an Athleta adds further evidence. But whereas the Charwar D. O. 

 bears on its slab back numerous large circles of Stephanoceras and Aspido- 

 ceras, I saw none such in this broken belt of D. O. 



No. 9 is a slight sloise of softish crimson brown and yellow stuff, 

 containing many molluscs. Seeing how closely the hard brown lower 

 Katrol beds lie on the D. O. of Charwar, one would have expected this 

 outer bit to be Katrol, but I saw no Katrol friends there : in fact the 

 beds held an Anceps — probably a washdown. One very deeply umbilicated 

 and globular Stephanoceras, which I cannot find in Waagen, also lay here, 

 but this too was probably a washdown. 



No. 10 would be Katrol beds, but they do not appear on this north 

 side : and on the south side, they must lie a good long ivay out. The Keera 

 Hill stands out on a peninsula stretching out into the Runn. A big ' bay ' 

 runs along its eastern base, and another one on its western. On its south- 

 west side the succession of ridge behind ridge stretches out to the main 

 line of hills of the coast : and here I expect will be found the whole 

 succession of these upper ^Jurassic beds. 



As you ride eastwards from the hill to your Camp, you will note the 

 occasional outcrop from the flat " bay " of ridges of rock, all dipping away 

 from the dome and evidently once a part of it — one ridge is over a mile 

 away from it. The sea which once covered the Runn has here eaten 

 away all the softer strata and left only these hard ridges standing. 



Another interesting point (geologically) is the question whether there 

 has been another great fault all along the base of these north hills of 

 Cutch. Mr. Wynne suggests it (Mem. J. S. I. ix, Art. i., p. 208). The Hubbye 

 Jooria, Keera, Nurrha and Soorha hills are all folded into anticlines — 

 much like the folds of the front hills of Charwar. Mr. Davies ' letter on 

 this subject in our last number helps to show that this is probable. Two 

 areas of Tertiary beds let in on the north — one you cross on your ride to 

 Oharee — suggest some such event. If so, the Runn rests on the upturned 



• One badly needs a better name. AH the Cutch Jurassics are properly " Upper 

 Jurassics" except the Putchum beds which are " Middle :" yet the Cutch series 

 is obviously divisible into two great groups.
