with traces of the Cephalopod-Bed above. Pseudogrammoceras 

 pedicum, S. Buckman, was found here. 



North of Hawkesbury the hill-country is greatly inter- 

 sected by ramifying valleys with lateral combs, but the geologic 

 structure is very simple, and readily-read with the aid of 

 a geological map. 



In Tresham Comb, there is an exposure of the Cephalopod- 

 Bed shortly beyond the second gate that is passed through in 

 ascending the valley ; while a little higher up (on the same side 

 of the wheel-tract— the right) is a quarry in the Freestones 

 and Upper Trigonia- and Clypeus-Gnts. Amusium personatum 

 occurs in the Freestones, and a specimen of Parkinsonia Park- 

 insoni (Sow.) was obtained from the Ragstones. Owing to 

 rock-shding, it was not possible to obtain rehable details of the 

 Top-Beds, but Fullers' Earth occurs above, and has yielded 

 Cristellaria cultrata, Montf., and Cytheridea Bradiana, Jones. 

 The usual Ostrea-acuminata-lAmesion^s are present, and con- 

 tain not uncommonly Pseudomonotis echinata (Sow.) . 



On the hill east of Alderley is the quarry in which Proso- 

 pon Richardsoni, H. Woodward, was found. The section was 

 described in the Geological Magazine for 1907 (pp. 82-84), so it 

 will suffice to say that it shows the ? Rubbly Beds, White 

 Oolite, Clypeus-Gx\i, Dundry-Freestone-Equivalent, and Upper 

 'Trigonia-Gxii. 



On Tor Hill is a large quarry in which the Freestones are 

 worked. In the shallower northern portion the Upper Tn- 

 gowta-Grit is seen above, and has i foot 2 inches above its base 

 a layer crowded with Rhynchonellce . 



Similar Freestones to those at Tor Hill have been worked 

 at Boxwell, and again in the conspicuous quarry on the hill 

 north of Coombe, near Wotton-under-Edge : that in which the 

 Dursley Rural District Council have placed a reservoir. Here 

 the basal layers of the Upper T rigonia-Gx\t are seen resting 

 upon the " Bored-Bed," at 20 feet below which is a rubble-bed 

 that may well be on the horizon of the Pea-Grit. In the lime- 

 stones below it Amusium personatum is particularly abundant. 

 To the north of Wotton-under-Edge, between Wotton and 

 Symond's-Hall Hills, are several sections which afford an almost 

 ■ complete view of the succession from the Cotteswold Sands to 

 the Great Oolite. The satisfactory nature of the locality
