Dr. Arthur Rowe — Uintacriims near Dover. 77 



iN'o. 9. This is a small and mucli obscured pit behind the Wheat 

 Sheaf Inn at Martin. The flints are in the form of large and smooth 

 nodules, and they do not run in courses. We were quite content to 

 find TJiniacrinus and the large Porosphatra glohularis in a list of only 

 six species. 



This completes the workable exposures surrounded by the 200 feet 

 contour-line on the Ringwould ridge. It will be seen that every pit 

 is in the Uintacrmus-chalk. 



We now cross the valley between the Ringwould and Free Down 

 ridges, passing on the way two poor exposures in the Micraster 

 cor-anfftdnum-zone at Great Coombe. The flints here are quite different, 

 being in courses, more rugged in shape, and with thicker cortices. 

 Moreover, the scanty fauna was that of the zone just mentioned. 



jS"o. 22. Ascending the Free Down ridge, we make for the east 

 side of Wood Hill to examine an old chalk-pit, and find that it is 

 completely overgrown with vegetation. By good fortune a new estate 

 is being laid out on the southern slope of this ridge, and in Victoria 

 Road a pit has been opened for the pui-pose of road-making. The 

 flints are here in the form of large smooth nodules, like huge potatoes, 

 and we found not a few plates and brachials of Uintacrinus on them, 

 as well as in the chalk itself. Out of seventeen species obtained here 

 only the name-fossil and Actmoeamax verus were of zonal value. 



No. 18. The railway made by the contractors to the new Harbour 

 Works, for the pui-pose of bringing ballast from Stonor, skirts the 

 northern edge of Langdon Hole, which is a deep coombe situated 

 midway between the east side of Dover and the South Foreland light- 

 house. Above the north-eastern corner of Langdon Hole the line 

 emerges through a short and shallow cutting which exhibits the usual 

 broken-up surface chalk. Knowing that a considerable thickness of 

 \h.e Micraster cor-anguinum zone is exposed in Langdon Stairs, and that 

 the railway cutting through the top of the cliff called the Cobbler 

 passes through the same chalk, it occurred to General Cockburn that 

 this insignificant little exposure at the north-eastern corner of Langdon 

 Hole was at a sufiicient elevation to bring in the Uintacrinus-'hdLnA. 

 He examined it and found the crinoid in abundance. 



We visited this section with General Cockburn at a later date, with 

 the result that our combined collecting furnished a list of 36 species, 

 among which we record the nipple-shaped head and barrel-shaped 

 columnarof5owr^?<^i!/crm«<s, the pyramidal shape-variation of -ficA/wocorys^ 

 scutatus, Infulaster rostratus, Micraster cor-anguinum, Conulus conicus, 

 Cyphosoma coroUare, TerehratuUna rowei, Kingena lima, TerehratuUna 

 striata, Rhynchonella plicatilis, Actinocamax verus, Pecten cretosus, 

 Peoten quinque-costatus, Ostrea vesicularis, Ostrea ivegmanniana, 

 Spondylus latus, Inoceramus cuvieri, Lima hoperi, Lima decussata, 

 Porosphmra glohularis, P. pileolus, P. patelliformis, P. arrecta, and 

 Spinopora dixoni. We give the more important fossils found here, as 

 this list is characteristic of the fauna found in the other pits. 



No. 11. In 1906 General Cockburn and Mr. Sherborn examined 

 a recently cut trench, 30 feet deep and 400 yards long, at the site of 

 the Duke of York's Schools, between Lone Tree on the Deal Road 

 and Frith Farm on the Guston Road, Dover. No contour-line is given,
