part 2] INFERIOR OOLITE OE THE CBEWKEKNE DISTBICT. 159 



The Top Limestones are at present (1916) being worked in a 

 quarry near Henley Farm (10). 



Crewkerne Station. — This is the locality 1 from which the 

 numerous specimens labelled ' Crewkerne Station ' were collected 

 in the past — especially by Mr. Darell. As the quarrying opera- 

 tions proceeded the sidings were extended, but now such operations 

 have ceased. The beds exposed were ' the upper limestones ' of' 

 Mr. S. S. Buckman ~ — a portion of the Top Limestones. In 1891 

 he referred them to the Zigzag Zone, 3 for lie informs me that his 

 'Broad Windsor district ' ^ included Crewkerne Station. Before 

 the more detailed separation of the Top Limestones was effected 

 the term ' Zigzag Zone,' he also informs me, sometimes included 

 deposits of scliloenhaclii date, and at other places they would be 

 reckoned trueUei. Thus the holotype of Terebratnla stibara 

 S. Buckman is stated to have come from the ' " Top Beds " of 

 Crewkerne Station (Somerset) . . . circa schlcenbachi zone.' 5 Zeil- 

 leria bicornis S. Buckman is recorded from the same beds and 

 locality. 



Railway-cutting, Crewkerne. — I have not had the oppor- 

 tunity of examining what remains unobscured of this section (12). 

 According to H. B. Woodward " the beds exposed here were : 



Thickness in feet i)iches.. 

 ' \_Scldoenbachi- 7. Pale rubbly oolitic limestones (zone of 



?truellei.~ Ammonites Pari in sou i) 6 



[Bradford ens is 6. Brown sbelly and ironsbot oolite 2 



5. Hard brown limestone passing- into com- 



Aneolioceras.~\ pact grey oolitic limestone 1 5 



[Sci'ssi] 4. Pale sandy and shelly limestones 3 



\_Opaliniformis.] 3. Brown sandy marl with Terebratnla infra- 



oolitica 1 



\_Opaliniformis]. 2. Indurated marl and sandy limestone with 

 Ammonites, Belemnites. Peeten Iseviradi- 



atus, and Rlnjnchonell a 1 3 



1. Sands with irregular bands and nodules of 

 calcareous sandstone : Peeten. Bhynchonella 

 cynocephala, Serpula 6 0' 



Before justifying the dates here suggested for the beds noted 

 by Woodward, it will be best to describe a section in Cat-Hole 

 Lane.
