150 MR. S. S. BTTCKMAN ON THE BAJOCIAlir [Feb. I9OI, 



{b) Note on the Upper Freestone Series. 



I may give here just an outline-section of what is perhaps the 

 northernmost exposure in the Cottes wolds. It shows 25 feet of 

 Freestone above undoubted Oolite-Marl. The Upton-Wold exposure 

 (Section IX, p. 135) could hardly be a local alteration of this 

 Freestone in that short distance ; it is most likely a higher bed than 

 any of the Freestone shown here. The following is the section : — 



Hill above Chipping Campden.

(c) Note on the Sandy Ferruginous Beds. 



There is a section in these beds at Creddiford Brook (Wood Farm) 

 near Guiting, on the road leading from Rowell Gate to Kineton — 

 the old British road known as ' The White Way ' — a west-and-east 

 trackway from the Vale of Severn to the Vale of Moreton. 



At Creddiford Brook are some 18 feet of a brown sandy stone, 

 and in about the middle of the section a bed yielding somewhat 

 plentifully, but not often perfect, specimens of Rhynchonella suh- 

 decoraia} It yields also lamellibranchiata, Nerincea, etc. ; so that 

 it is quite a fossiliferous exposure. 



The interest attaches to RliyncJionella suhdecorata^ which has been 

 found, though sparingly, in this deposit in several places on the 

 western flank of the Cotteswolds, accompanied sometimes by 

 characteristic ammonites which enable the horizon to be identified 

 on the one hand with the top of the Yeovil Sands (basal Inferior- 

 Oolite beds of Dorset-Somerset) and with the Northampton Sands 

 on the other. 



Here in the ^N'orth Cotteswolds, where the distinctive ammonites 

 seem to fail, the Rhynclionella is sufficient ; and it is also the same 

 Rhynchonella that distinguishes certain basal ' Inferior-Oolite ' beds 

 at Hook Norton (Mr. E. A. Walford kindly sent me specimens 



^ The large form figured by Davidson, Monogr. Pal. Soc. 'Brit. Foss. 

 Brachiop.' vol. i (1852) pi. xviii, fig. 10, & ibid. Appendix (1855) pi. A, figs. 23 

 & 25 ; not the small form of pi. A, figs. 24 & 26, which is another species, and 

 occurs quite at another horizon.
