 The following communications were read : — 



1. ' The Eocene Deposits of Devon.' By Clement Reid, Esq., 

 F.L.S., F,G.S. 



A re-examination of the area around Bovey has led the author to 

 think that Mr. Starkie Gardner is probably right in referring the 

 supposed Miocene strata to the Bagshot period. Lithologically as 

 well as botanically, the deposits in Devon and Dorset agree closely. 

 The gravelly deposits beneath the Bovey pipeclays arc also shown 

 to belong to the same period, and not to be of Cretaceous date. This 

 correction has already been applied by Mr. H. B. Woodward to a 

 large part of the area. The plateau gravels capping Haldon are 

 also considered to belong to the Bagshot period, for they correspond 

 closely with the Bagshot gravels of Dorset to the east, and of the 

 Bovey Basin to the west, and possess peculiarities which distinguish 

 them from any Pleistocene Drift. 



2. ' On an Outlier of Cenomanian and Turonian near Houiton, 

 with a Note on Holasier alius, Ag.' Bv A. J. Jukes-Browne. Esq., 

 B.A., F.G.S. 



Although au outlying* patch of Chalk in the parish of Widworthy 

 was mentioned by Fitton and marked on De La Beche's map, it has 

 not yet been described. The tract is about 4| miles south-west of 

 Membury, 3 \ miles east of Honiton, and about 7 miles from the 

 coast at Beer Head. 



The quarries at Sutton are almost entirely obscured by vegetation, 



but the following approximate section was obtained from a mason 



who formerly worked in them :— f eet#

1 . ' Grizzle ' (a hard calcareous sandstone). 



The Freestone, used locally for building, is evidently identical 

 with the Beer Stone. 



Another small outlier of Turonian Chalk occurs at Wilmington, 

 restiug on hard quartziferous limestoue with glauconitic grains, 

 which yielded fossils indicating its equivalence with the uppermost 

 Cenomanian beds of the coast-section. Below this come other 

 sandstones, sometimes containing lumps of ' grizzle,' giving a total 

 thickness of 40 or 42 feet to these beds on the whole — a much 

 greater thickness than is ever attained on the coast. A list of 

 fossils is appended to the paper, and the author discusses the 

 affinities of Holaster altus, throwing out the suggestion that there 

 is a gradation from H. Bischoffi, through H. alius to H. subglobosus. 



3. ' Cone-in-Cone : Additional Facts from Various Countries.' 

 By AY. S. Gresley, Esq., F.G.S. 



Examples of flinty stone in the ; fire-clay series' of the Ashby 

 coalfield exhibit ' areas of conic structure lying unconformably.' 

 In the same stratum of shale are large masses of the same flinty
