On two New Species of Corals in the Lias of Warwickshire. 

 By the Eev'. P. B. Erodie, M^L.,F.G.S. 

 The author observed that an unusually large species of Montlivaltia*, as yet un- 

 deseribed, had been met with in the Middle Lias, near Shipston-on-Stour, where it 

 is abundant, the largest specimens measuring 5 to 6 inches in length, and 3 in dia- 

 meter acros3 the calicular surface, varying in size and form, some being more elon- 

 gated and others more cyathiform. Most of the corals are unfortunately much 

 weathered, the epitheca being rarely preserved, but better ones might be obtained 

 by quarrying. One example of the so-called Montlivaltia Hairnet was described 

 from the Lower Lias, near Itugby. Though abundant in Nottinghamshire, it is 

 rare in Warwickshire, and is known also in Ireland, where it was first observed by 

 Mr. Tate. It may perhaps be questioned whether this coral is correctly assigned 

 to the Belgian species. Of late years the number of British Liassic corals has 

 greatly increased, and when all are published and described, the list will certainly 

 equal, if it does not exceed that already known in foreign countries. 



Remarks on the Drift in part of Warwickshire, and on the Evidence of Glacial 

 Action which it affords. By the Eev. P. B. Buodie, M.A.,F.G.S. 

 The extent and character of the low-level drift round Warwick and Leaming- 

 ton and along the valley of the Avon, were first described, containing in places the 

 usual mammalian remains, but no flint implements had yet been detected. Of older 

 date belonging to the glacial period, was an extensive deposit of drift occupying 

 the high table-land over an area from G to 12 miles N.N.W. and W. of Warwick. 

 Bounded pebbles and boulders of various size and diverse mineral composition 

 are scattered in greater or less abundance over the whole of this tract, including 

 granite (rarely) and other more ancient rocks. Here and there some large erratic 

 blocks are met with, but generally the pebbles are of small size, consisting mostly 

 of sandstone and quartz. Flints little abraded are nowhere absent from this drift, 

 though more abundant at some spots than others. Fossiliferous rocks are very 

 scarce, but at one place pieces of chalk rounded and scratched with flints, green- 

 sand, oolite, lias, magnesian and mountain limestone, and rounded boidders of older 

 formations were indiscriminately mingled together. Hence it was inferred that an 

 iceberg had deposited a portion of its load there. The other erratics consist of the 

 usual detritus, supposed to have been derived by the same means from the north 



Generally, though much of it may have been transported from other directions, 

 'he most novel and interesting fact was the discovery of Orthis redux, Lingida 

 Lesueuri, a species of Modiolopsis, and Trachyderma serrata in the quartzose peb- 

 bles and sandstones, identical with those figured and described by Messrs. Salter 

 and Vicary in the Quart. Journ. Geol. Soc, from the New Bed Sandstone at Bud- 

 leigh Salterton in Devonshire \. It was inferred that these numerous pebbles of a 

 similar lithological character had the same origin as the Devonian ones, and that 

 in all probability the upper red sand and marls with pebbles once capped the Keuper 

 in Warwickshire, and the softer material having been denuded, the heavier masses 

 were scattered about as they are now found. The few fossils hitherto found in them 

 by the author are at all events Lower Silurian species belonging to the Armorican 

 sandstone, and the quartzites of Ivray in Normandy. 



A list of some of the chief constituents of the drift was appended, showing its 

 prevailing contents to be of a very mixed character, though the sandstone and quart- 

 zose pebbles largely predominate. 



Organic Remains of the Coal-Measures. By L. P. Capewell. 



* It appears that this species occurs in the Lias on the Continent, where it was de- 

 scribed by Fromentel et Ferry, under the name of Montlivaltia cuneata—M. Cherring- 

 tonensis, Duncan, MS. 



t These shells were examined and identified by Mr. Woodward, Mr. Salter and Mr. 

 Vicary at the late Meeting of the British Association in Birmingham.
