26 DUNDEY GASTEROPODA. 



This species in that case has the same rauge as C. Heddington- 

 ensis, Sow. ; as both these are widely spread geographically, we 

 need not be astonished at their vertical range. 



Locality — Cleeve Hill, near Cheltenham. Inf. Ool. 



Though' we have no specimens from Dundry, we have noted 

 this species here. We would not give undue weight to dubious 

 zoological distinctions for the sake of rounding a geological 

 system.

"We found a specimen of this shell, in company with Mr W. 

 S. Mitchell, in a roadside section, west of Midford, near Bath. 



Imperfect as it is, it agrees perfectly with the description of 

 the authors cited, though they give the Coralline Oolite as its 

 position. 



Deslongchamps has apparently been led by mere accidents of 

 fossilisation in making a separate species for the Inferior Oolite 

 form. 



Our single specimen is from the inferior Oolite, not far above 

 the ''Midford Sands." It would thus seem to have a considerable 

 range. 



One specimen only. 



Locality — Midford. Inf. OoL
