East of Crewkerne the Aalensis Beds 'attenuate," and fail 

 somewhere between North Perrott and Yeovil Junction, for they 

 have not been delected in the Sherborne district.- A mile-and- 

 a-half east of Crewkerne, at the Manor-House Quarry, North 

 Perrott, the evidence for Aalensis Beds consists in the occurrence 

 of the zonal ammonite in a deposit having a decidedly remani'e 

 aspect, which rests on the Perrott Stone. 



( xxvi) Opalinifornie Beds. — At Chideock-Quarry Hill the 

 Opalinifornie Beds consist of 3 — 



Thick lie** in feet incite*.

Ammonites, cf . Ca na va eel lo 1

Sands and sandburrs. Khynchonella of ci,nn- 



ph a la -pattern ; Opalinoid Ammonites 3 8' 



and the equivalents of these, together with the bottom stratum 

 (1 foot thick) of the Scissum Beds, constitute the Brachiopod 

 Beds at Whaddon Hill. 



These Opalinifornie Beds extend into the Crewkerne district, 

 and are well exposed in a roadside section in Cat-Hole Lane 

 south of Crewkerne (p. 160), where the deposits (rt 1 ) and (a 2 ) 

 represent bed (6#) of Chideock-Quarry Hill. Deposits (rt 1 ) and 

 (7r) of Cat-Hole Lane are represented at the Manor-House Quarry, 

 North Perrott, by the greater portion of the sandy clay (Bed 3) 

 above the Perrott Stone (p. 163), and at Barrows'-Hill Quarry (32) 

 by a very similar deposit (p. 169). 



(xxvj Scissum Beds.- — These are well exposed at the Conegar- 

 Hill Section, Broadwindsor, where they consist of irregular 

 sandstone and sand-rock with intervening deposits of sand. The 

 harder portions are replete with fossils, among which the most 

 noticeable are — Gryplicea cyyuoiJcs Whidborne, JPlioladoihya 

 jidicula J. de C. Sowerby, Lima inoceramoides Whidborne, and 

 Volsella sowerbyana (A. d'Orbignv |. 



Similar beds extend into the Crewkerne district, and are to be 

 seen in the sections— opposite Hill Farm, South Perrott (5) ; near 

 Lecker Bridge (4) ; and near Well-Spring Farm, near Misterton 



(7). 



Farther north, however, at the Manor-House Quarry, North 

 Perrott (27), and Barrows'-Hill Quarry I 32 ), softer beds, consisting 

 mainly of sand, are seen. They are rich in specimens of Ai'laco- 

 thyris blahei (Walker). llhynclioacJla cynocephala auctt.. and
