2. The clay exposed in the cutting and southern portion of the tun- 



nel was of armati date. In that portion near the entrance to 

 the tunnel specimens of Ammonites (Microceras) subplani- 

 costa Oppel, were most abundant. 



3. The clays exposed in this cutting were also of armati date. Above 



them, in the southern portion of the cutting, the gravel-deposit 

 was clearly displayed, measuring, in its thickest part, 8 feet. 



4. In the well-known, but now closed Folly-Lane pit, the lower 



portion of the Armatus-Zone was formerly exposed, the Mont- 

 livaltia-rugosa- and Hippopodium-'Beds (which occur about the 

 junction of the Armatus- and Raricostatus-Zones), and the 

 Raricostatus-'Beds. Crowds of small fossils could once be collected 

 from the weathered clay-faces, together with many small am- 

 monites (principally Microceras subplanicosta). Wright has 

 referred to this section (Lias Ammonites, p. 55, Pal. Soc), and 

 so have several other authors (H.B. Woodward, " Jurassic 

 Rocks of Britain — The Lias, etc.," vol. iii. (1893), p. 143 ; 

 L. R., " Handbook Geol. Cheltenham," (1904), p. 43). 



5. Here higher beds, the Valdani-'BeAs, were exposed when a deep 



trench was cut along the road between the brook and the 

 Pound. One thin conspicuous white layer was literally made 

 up of the crushed valves of Inoceramns ventricosiis (Sowerby). 



6. The V aldavii-C\a.ys were the last clays dug at the Harp-Hill Brick 



Works. Fragments of Acanthopleuroceras valdani and allied 

 forms abounded. In times past, higher beds, the Striatus- and 

 Capricornits-'Beds have been worked here (vide Quart. Joum. 

 Geol. Soc, vol. Ixii., 1906, p. 585 — footnote). 



7. This is the only clay-pit in work in the area under consideration 



(Plate xxxiv., figs, i and 2). The clays exposed belong to 

 the Valdani- and Striatus-Zon^s ; but the latter zone also 

 includes the " Yellow Lias " — that is, the yellow clay, which 

 is so crowded with richly-fossiliferous nodules. The Valdani- 

 Beds also contain beautiful pyritized specimens of Ammonites 

 (Rhacoceras) ibex Quenstedt. This is interesting, for Mr H. 

 B. Woodward, F.R.S., states, "so far as I know the zone of 

 A. Ibex is nowhere distinctly to be recognized in this country." 

 (" Lias of England and Wales, etc." p. 67). 



8. Yellowish micaceous clays with ferruginous nodules were seen in 



a temporary excavation, but no evidence was obtained where- 

 with to date them precisely. 



9. An excavation here revealed very tough blue clay, but as no 



fossils were obtained, it was not possible to determine the date. 

 10. Specimens of Ammonites (Oxynoticeras) oxynotus Quenstedt, were 

 obtained here from a temporary excavation and also from near 

 Dean Close School (ii). When the railway-cuttings near the 

 Midland Station were made, a number of fossils indicative of 

 the Oxynotus-'RQds were obtained. 



12. In this cutting, near the place indicated, ammonites indicating 



Raricostaius- and Armatus-Zones were obtained. 



13. The cutting under St. George's Road is through the Armatus-'Beds. 



14. Clay dug out of excavations made to receive the foundation of the 



piers supporting the arch over Millbrook Street yielded Zeilleria, 

 Spiriferina, Serpula, Chlamys, Gryphcsa and belemnites. It is 

 of about raricostati hemera. 



15. A large number of fossils have been obtained from time to time 



from excavations made on the Gas-Works grounds. They 

 indicate deposits of oxynoti, raricostati and armati hemers.
