13. Cat-Hole-Lane Section, Crewkerne. 



Thickness in feet inches. 

 Scissi Sandstone in loose pieces. 



'Opalinifonnis. (a 1 ) Brown and purplish-grey- streaked sandy- 

 marl; belemnites, Gryphsea sp. (some of the 

 less gryphoid form of an Ostrsea-lcnorri Voltz 

 aspect), Variamnssium Iseviradiotvm (Waa- 

 gen), Aulaeothyris blakei (Walker), Bhyncho- 

 iiella cynocephala auctt., Terebratula of the 

 T. - haresfieldensis - Group, T. whaddonensis 



S. Buckman : seen 1 



(a 2 ) Brown marly sandstone with an occasional 

 ill-preserved opalinoid ammonite ; belemnites, 

 Pleiwomya sp., Rhynchonella cynocephala 

 auctt. — all rare 8 



<Op<diniformis. (b) Ammonite Bed. Sandstone, very fossili- 

 ferous ; cf. Canavarella toma S. Buckman 

 (periphery not acute enough and radial line 

 hardly sufficiently curved), Cypholioceras sp. 

 nov. (a morphic equivalent to species prior 

 to Lioceras uncinatum S. Buckman), Walkeri- 

 ceras subglabrum S. Buckman (Monogr. Amm. 

 Inf. Ool. Series, pt. ii, 1888. pi. xiii, fig. 9), 

 belemnites, Pleuromya sp., Variamussium 



laeviradiatum (Waagen) (common) 1 



(c) Sands and sandburrs ; Goniom/ya sp., Pleuro- 

 mya sp.,Pteria (Oxytoma) sp., Variamnssium 

 laeviradiatum (Waagen), Serpula tricarinata 

 auctt. (common) : seen 1 6 



Beds {a 1 ) and (« 2 ) would seem to be the equivalent of the 

 Ttusty Bed of the Conegar-Hill Section, Broad Windsor, and of 

 Whaddon Hill, near Beaminster ; 1 while the Ammonite Bed is 

 comparable with the very fossiliferous sandstone bed, bed G h, at 

 -Chideock-Quarrv Hill, 2 and the similar bed immediately below the 

 Rusty Bed at Whaddon Hill. 3 



Referring now to Woodward's section in the railway-cutting, 

 one can have little doubt that bed (c) at Cat-Hole Lane is equiva- 

 lent to the top portion of his Bed 1 : the Ammonite Bed to his 

 Bed 2 : and beds (« 2 ) and (a 1 ) probably to his Bed 3. His Bed 4 

 is probably of scissi date: Beds 5 and 6 probably of murchisonai- 

 Ancolioceras hemerae, with iron shot rock (as at the Misterton 

 Lime works) attached to the top : while his Bed 7 embraces the 

 Top Limestones. 



Upon-Lang Quarry, Crewkerne. — The best section of the 

 Top Limestones in the neighbourhood of Crewkerne is at this 

 quarry.
