The Midford Sand is exposed in many of the road- and lane- 
cuttings between Ilminster and Yeovil. From the lower beds of 
sandy marl at White Lackington, near Ilminster, Mr. S. S. 
Buckman records Ammonites jurensis, A. insignis, A. dispansus, 
and a fragment like A. striatulus, as occurring together.* 
By New Hall, west of North Perrot Church, there was a quarry 
showing about 18 feet of false-bedded shell-limestones, inter- 
bedded with buff sands and sandy limestones, that (as previously 
mentioned) occur locally in the upper part of the Midford Sand 
in this district, and are well represented at Ham Hill. The 
shell-fragments are mostly indeterminable as to species, consisting 
of Ostrea, Pec ten, and Amcula ; but Mr. Rhodes obtained Pecten 
demissus and Belemnites Voltzi ? 
Chiselborough Hill, according to Bristow, is capped by a thin 
irregular shelly limestone, which has been worked out in holes, 
and not systematically quarried. In the road by the knoll to the 
south-west of Chiselborough, we find a section of micaceous and 
loamy sandv^, with spherical concretions of calcareous sandstone, 
and these become shaly towards the junction with the Upper Lias 
clays below. A similar section was exposed in the deep lane 
leading from Montacute Priory towards Ham Hill. 
The celebrated building-stone of Ham (or Hamdon) Hill has 
long been recognized as a member of the Inferior Oolite, although 
opinions have differed on the question of its precise position in
