in a disused quarry just west of Cold ft. ins. 

 Lower Tri- Comfort Cottages, on the right-hand side of 



gonia-grit. the road from Gloucester to Oxford, is 



30 feet. 1 Therefore 30-9 gives 21 



Upper Free- 9. From the top of the Upper Freestone to an 

 stone. exposure of Oolite Marl on the left-hand 

 side of the road, just east of Cold Comfort 

 Cottages is 18 feet. Immediately W. of the 

 cottages, on the same side and in the same 

 field as the top quarry, is an Upper Free- 

 stone quarry ahout 15 feet deep 18 



Oolite Marl. 10. Marl with Terebrattda fimbria and character- 

 istic fossils. 



I am indebted to my friend Mr. Charles Upton, who made ars 

 independent section of the quarry, for calling my attention to 

 certain details here given. He has also collected Terebratula 

 Wrighti and WitcJiellice from here, and gives them the same position. 

 I have, moreover, a small spinous Sonninia aff. Sowerbyi, found loose, 

 in a matrix agreeing with Bed 5. 



The beds above the Notgrove Freestone (6) are more or less 

 broken np and disturbed. They are mixed with more or less earthy 

 marl, and it is in this that Terebratula Wrighti is found. Its general 

 level is from 1| to 2 feet above Bed 6; but one specimen has been 

 found 8 inches above that bed. Of the beds above 6 there are 

 only 3 feet shown directly in the section ; but by working farther 

 east a higher horizon, the one with Acanthoihyris, is found. Owing 

 to the disturbed nature of the upper beds it was not possible to 

 ascertain the exact thickness of this Acanthotliyris-hed ; but it was 

 estimated at not less than 1 foot. This is the same Acanthothyris 

 as that which is found in the section at Lineover, by the roadside ; 

 and, therefore, though no Witchellia and no specimens of Terebratula 

 Wrighti were found there, this little fossil is to a certain extent 

 palaeontological evidence of the identity of the ragstones which 

 at Cold Comfort and at Lineover lie above the Notgrove Freestone. 

 These ragstones are not Upper Trigonia-grit : that is proved at Cold 

 Comfort by the ammonites — Witchellia? are indicative of a deposit 

 which was laid down 4 hemeree before that of the Upper Trigonia- 

 grit (Garantiance hemera). 2 At Lineover these ragstones are capped 

 with Upper Trigonia-grit ; at Cold Comfort the same bed must have 

 lain almost immediately over the WitcJiellia-grit, though it could 

 not be found in that position. There are, however, brachiopoda of 

 the Upper Trigonia-grit to be found on the spoil-heaps, and blocks 

 with the same fossils : these have probably been left among the 

 thin soil which capped the quarry, and some of them may be 

 wedged among the top beds. 



The Witchellia-grit has been, in part, noticed by "Wright as the 

 Perna-bed ; my reason for calling it by its present name is that this 



1 The above measurement (30 feet) must be considered approximative, the 

 quarry being much inclined.
