MESSES. S. S. BTJCKMAN AND E. WILSON [Nov. 1896, 



the same as, or just below Bed 7 of Section IX. The Terebratula in Bed 7 is 

 presumably T. cortonensis ; and the ammonites are probably Hyper lioceras, 

 or allies of Lioceras concavum. The four or five lowermost beds were presumably 

 deposited during the Murchisona hemera, and have probably yielded some of the 

 fossils of that date now in the Bristol Museum. Compare with Sect. X., Bed 5. 



The correlation of the deposits of Section IX. is easy — it is a 

 repetition of the northern roadside quarry. The noticeable points 

 are that the Ironshot and the Witchellia-bed. are present, and that 

 there is only a thin deposit separating the Coralline from the Iron- 

 shot, so that there are no Freestone beds below the Coralline to be 

 expected in this part of the hill. 



The last section which we have to mention is near Hackledown 

 Farm, situated on the south-western corner of the southern spur, 

 which is separated from the main mass of the hill by the valley 

 below East Dundry. 



Section X. — Raclcledoiun ] Farm. 



ft. ins. ft. ins. 

 Coralline 1. Pale greenish-yellow coralline rubble. 



Beds. Aulacothyris carinata about 4 



Freestone 2. Thin-bedded, white limestone with 



Equivalent. marl about 4 



Sauzei and 3. ' The Ironshot.' Spkaroceras Sauzei, 



perhaps and a number of species of the Son- 



Witchelli^e. ninia propinguans-type. Probably also 



including the bed at the base of the 

 Ironshot, from which so many species 

 of Witchellia come. This quarry has 

 yielded a good series, but they are 



difficult to obtain in situ about 3 



Sonninle to 4. Beds below the Ironshot. Several beds 



Concavi. of pinkish-grey limestone with marly 



partings. Hyperlioceras about 3 feet 



6 inches from the base about 5 6 



MuRCHisoNiE. 5. Somewhat irregularly bedded and 

 cross-jointed, very dense, pinkish-red, 

 crystalline limestone with small scat- 

 tered iron grains, getting more com- 

 pact upwards. The top of the bed is 

 somewhat planed off, and covered with 

 ferruginous nodular lumps. Zeilleria 

 anglica, Ehynchonella Stephensi ?, 

 Myacites aff. jurassi 2 4 9 



6. Tough crystalline limestone, yellowish 



grey, with scattered iron grains 1 7 



7. Earthy limestone with scattered iron 



grains, with interwedgings of irregu- 

 lar, compressed, ironshot, sandy clay. 

 Ludwigia cf. obtusa on spoil-heap 



with matrix similar to this bed 5

 what crystalline limestone. Phola- 

 domya fidicula 2 8

2 From this bed, judging by matrix, a fine Ludwigia aff. obtusa, Quenstedt, 

 in the Bristol Museum, was obtained ; also the specimens of Cirrus.
