550 Revieivs — Hewton's Eocene and Oligocene Mollusca, 



III. — Proceedings of the Cotteswold Naturalists' Field Club 

 FOR 1890-91, Vol. X. Part 2, 1891. 



THREE of the four papers in this Number of the Proceedings 

 are devoted to Geology ; even the address of the President, 

 Mr. W. C. Lucy, is largely concerned with the same science, giving 

 as it does accounts of excursions to Lydbrook and Symond's Yat, 

 May Hill, Eastnor, Swindon, and Avebury. 



The first paper is by Mr. H. D. Hoskold, and entitled "Geological 

 Notice upon the Forest of Dean." In it the author gives a very full 

 account of the formations, referring to the early work of Buckland 

 and Conybeare, David Mushet, De la Beche, and others, and adding 

 a number of new records of the strata passed through at various 

 collieries. He estimates that the Forest of Dean contains nearly 

 250 millions of tons of coal available for use — the amount raised 

 during 1888 was a little over 800,000 tons. 



Professor Allen Harker contributes a paper " On the Geology of 

 Cirencester Town, and a recent discovery of the Oxford Clay in a 

 deep well-boring at the Water Works." He gives accounts of 

 various wells in the neighbourhood, and announces the discovery 

 of a small faulted tract of Oxford Clay that was proved by a boring 

 at Lewis Lane, Cirencester. Important details of the Forest Marble 

 and Great Oolite are given. 



Dr. Frederick Smithe and Mr. W. C. Lucy furnish " Some 

 Remarks on the Geology of Alderton, Gretton, and Ashton-under- 

 Hill." Their descriptions refer to the Middle and Upper Lias, and 

 they give lists of fossils from these formations at Alderton Hill, 

 Among the records are Ammonites radians from the Upper Lias 

 (lower part), and A. aalensis from the Middle Lias; identifications 

 which we anticipate will be doubted by those who believe in the 

 rigidity of zones.

THIRTY-SEVEN years have elapsed since the historic "Catalogue 

 of British Fossils," by Professor John Morris, saw its second 

 edition published ; a modest work of 372 pages, 8vo., embracing all 

 classes of fossil-remains. 



Since that date, a long array of British Fossils have been figured 

 and described, many groups of the Invertebrata being fully Mono-
