masses of pale yellow crystals. Several of the blocks were from one 

 to two feet thick and quite pure. That the sequence of the beds 

 below is the same as at Hook Norton can be traced in an old quarry 

 in a garden on the other side of the valley, where the lower lime- 

 stones have been worked. The fawn-coloured sandy limestones, there- 

 abouts the top beds of the Inferior Oolite, may be seen, in several 

 other sections on the south side of Swerford Park, attaining a thickness 

 of about twenty feet, and often banded with ferruginous stains. At 

 Colls-Coombe barn they are to be seen capped with black clay, which 

 Mr. Hudleston* has made a boundary-line between the Inferior 

 and Great Oolite beds of the region. 



Between South Newington and Wiggington, about half a mile west 

 of the former, a now disused roadside quarry presents conditions 

 slightly varying from the Hook-Norton type, in which Astarte minima 

 is rarely associated with plant-remains. It shows : —

7. Violet-coloured limestone, sandy at top and harder at base, with 



black shining concretions and oysters 1 4

A fault crosses the quarry from E. to W., bringing down a mass 

 of fawn-coloured sands with the ordinary black-clay capping. 



On ascending the Otley Hill, two miles and a half north-west 

 by west from Hook Norton, one notes in the fine panorama of 

 Midland scenery the high plateau of Tadmarton throwing off, on its 

 northern flank, the tributaries of the Stour to flow westward, whilst 

 from the base of the ridge on which one stands the stream springs 

 to join the Swere, which meanders in its journey to the valley of the 

 Cherwell round the knolls crested with the villages of "Wiggington, 

 South Newington, and the Barfords. The rich red colour of the 

 arable lands of the Middle-Lias marlstone lies in pleasant contrast 

 about the green slopes of the Lias vales. Near the top of the hill, 

 and in a small quarry by the side of the road leading to Traitor's 

 Ford, some fossiliferous beds are to be seen, the equivalent of series 

 B and C of the Hook-Norton cutting, mingled with the remains of 

 an apparently lower horizon. Prof. Judd has described the sectionf 

 and has given a list of the fossils, which I quote with additions by 

 Mr. Windoes and myself. See Table C (p. 242). 



One is confronted here by the difficulty of an apparent admixture 

 of forms supposed to be restricted to both high and low Cotteswold 

 horizons. The former is evidenced by Trigonia signata and T. pro- 

 ducta, and the Terebratula globata of Prof. Judd's lists ; the latter
