UPPER LIAS : KIRTON LINDSEY. 287 
attenuation not inconsistent with the view of the overlap of the 
Inferior Oolite series. 
From the railway-cutting north of Kirton Lindsey, Am- 
monites communis, A. scmicelatus, and other fossils were obtained. 
The clays have been worked for brick-making near Kirton 
railway-station. In a well at Roxby Grange, dark grey shales 
vfhhA.scrpentimts, were found beneath the Basement-beds of the 
Inferior Oolite : here again the evidence suggests unconformable 
overlap of the newer beds. 
From this region we pass into Yorkshire, and the beds in that 
region are described by Mi 1 . Fox-Strangways. 
It is possible (as mentioned p. 244) that traces of Upper Lias 
may be preserved at Frees in Shropshire, but nowhere else in 
England or Wales have we any reason to suspect the presence of 
the formation in outlier;:! far away from the main outcrop.
