MISCELLANEOUS NOTES. 797 



that of Per. rehmanni at the furcating of the ribs : but the outer whorl had 

 lost all spines. Unfortunately the specimen was only partial, and much 

 corroded. Some slabs on the top of the ridge were coated thickly with 

 clusters of a diminutive blue white shell, straight, tubular, tapering. I 

 found the same on the summit of a knoll in the Ler Hamundra Ellipse. 

 I cannot find any sign of this species in Zittel's Palaeontology Text Book. 



The sides of this knoll, which is the limit of the Sub Anceps beds, slope 

 down to nullahs : and from underneath the knoll beds, there sweeps up the 

 great grey mass of rock which proved so damping in the Ler Hamundra 

 Ellipse. At this point the strata of these barren grey rocks does not seem 

 to be so thick as they are three miles west. There they are of perhaps 200 

 feet thickness : here perhaps only 50 feet. The ever-handy nullah shows 

 them in profile. They run sloping up at the same angle as the outlying 

 strata, but as they come more east, they dip round in an easy curve so 

 that they shut in the whole central core of the hills. This central core 

 runs in a light yellow ridge, over topping the fallen-away husks of the 

 barren grey sandstone. It is yellow with dried grass: its matter is dark 

 crimson of which patches appear here and there. 



Now this core is the exciting part of the whole thing : the main hope 

 with which I started for these hills was that of finding golden oolite here. 

 The books make no mention of the golden oolite of Keera existing here : 

 but by the usual sequence of rocks, it should be here. The specimens 

 described by Waagen as coming from this neighbourhood were only ten in 

 number, 8 of which were from the D. O. The existence of a Nautilus 

 kumagunensis seems to have puzzled him : and the finding of a Staph, 

 dimerum (a Macrocephalus species) is located as "N. W. of Lodai" — which 

 would be out in the Runn. If the previous explorers had negotiated the 

 central core of those hills, the solution would have been found. The 

 central ridge is of the Macrocephalus age. After much prowling over the 

 small broken crimson cubes of the summit, an Ammonite — much like Steph. 

 diadematum was discovered. Other specimens gradually followed — one and 

 all repeating the form and features of the StepJianoceras of Keera Hill. 

 To say that this or that specimen is a Dimerum or Grantanum is not allowed 

 until one has more of the types available for comparison, but I have no 

 hesitation in believing that these crimson beds were being deposited in the 

 seabed at the same time that the golden oolite and shales of Keera were 

 being laid down. The Stejihanoceras which I have found resemble the 

 following of Waagen's list : — Diadematum, Chariense, 3Iacrocephaluvi, Sub- 

 trapeziuin, Dimerum, Grantanum , and also Arenosum (which latter Waagen 

 places in D. O. beds). 



Now I had no time to explore the north side of the ridge. From the 

 summit, by the Jhakle temple, one could see a very deep nulla side running- 

 north, cutting deep down into the strata of the beds a very short distance 

 north of the summit of the anticline. Such a nullah should (if the ground 

 is not faulted) reveal the section of the beds to a good depth below this 

 crimson Macrocephalus stratum. There are said to be deposits of black 

 marble just about there : none of these beds so far examined on the south 

 side of the anticline show any traces of marble. Nor have I explored the 

 west end of the hills — beyond discovering once the rise of Katrol beds 

 (dipping W) some way from the west end of the main mass of the hills. 

 From a distance one can see that the main yellow ridge (yellow with grass) 

 runs persistently to well nigh the west end of the mass. Hence these 

 notes do not profess to give anything like a complete account of the hills. 

 Yet as they may be of use to a scientist who may desire to thoroughly 

 exploit the Cutch Ammonites, I send them as they stand. 



The Lytoceras of the Athleta beds referred to above is only the fragment
