No additional information with regard to the Westbury and Cotham 

 Beds supplementing that given in the above record is necessary. 



Camel-Hill Quarry (3) exhibits the sequence of deposits from 

 Bed 40 to 122 of Moore. Moore's numbers were applied to the 

 beds that he saw in the railway-cutting, so it will be understood 

 how persistent are the individual layers in this inlier. 



There is no need for a detailed notice of this section at Camel 

 Hill : all the stratigraphicai information that can be required is 

 given in the record on pp. 46-47 ; but it may be as well to empha- 

 size the point that the local Insect and Crustacean Beds are very 

 •distinctive deposits, and occupy a position in this neighbourhood 

 inferior to the Saurian and Ostrea Beds. 



In the quarry distinguished as 4 on the map (fig. 3), the highest 

 bed seen is Bed 84 of Moore and the lowest his Bed 71. The Sun- 

 Bed is a ' ragged ' rock with longitudinal borings, and is overlain by 

 clay, the bottom layer of which is of a conspicuous chocolate colour. 



In Quarry No. 5, the white limestones of the Langport Beds are 

 seen at the base, and then above them come beds corresponding to 

 those numbered 79 to 92 (according to Moore's notation) of the 

 Camel-Hill section. 



In Quarry No. 2, the yellow bed (65) is at the top, and below 

 a succession similar to that at Camel-Hill Quarry can be made out. 



In the wood close to the railway-cutting is the Sparkford-Hill 

 Quarry. The Langport Beds are very fossiliferous at certain 

 horizons, and have yielded Pseudopedina tomesi (Wr.), Oardinia sp., 

 Plagiostoma valoniense (Defr.), Dimyodon intus-striatus (Emmerich), 

 <Grammatodon hjcetti (Moore), ostracods, etc. The lowest beds visible 

 are the massive limestones in the neighbourhood of Beds 41 to 43. 

 By following up the section, the same horizons and deposits as at 

 Camel Hill can be distinguished, and the massive-looking stratum 



1 Beds 11 to 15 (or 8 to 12 of Moore) are seen cropping out in the side of the 

 track near Camel-Hill Quarry (see map, fig. 3) ; there however, Bed 13 is not a 

 sandstone, but a fossiliferous limestone like Moore's ' Flinty Bed ' of Crocombe.
