4. — Tawney, E. B. Museum Notes — Dundry Gasteropoda. Froc. 

 Bristol Nat. Soc, new series, vol. i. part i. pp. 9-59. [1874.] 



This communication is the result of a critical examination, by Mr. 

 Tawney, of the Gasteropoda, now in the Bristol Museum, which 

 have been obtained from the Inferior Oolite of Dundry Hill. He 

 records sixty-six species in a determinable condition, besides casts 

 and imperfect fragments of shells. Of the genus Pleurotomaria 

 alone there are twenty-six species. 



Out of the total number of species, no less than nineteen do not 

 appear to have been hitherto figured, and fifteen species do not 

 seem to have been cited before in British lists. The paper is illus- 

 rated by three well-executed lithographic plates. H. B. W. 



6. — Tawney, E. B. The Coal Question. Proc. Bristol Nat. Soc, new 

 series, vol. i. part i. pp. 71-84. [1874.] 



The author reviews the general results of the Eoyal Coal Com- 

 mission, and discusses the future prosperity of England, H. B. W. 



6. — Stoddart, W. W. Geology of the Bristol Coal-field. Part I. 

 Proc. Bristol Nat. Soc, new series, vol. i. pp. 115-126. [1874.] 



This part contains a general account of the physical geography 

 of the district, with list of formations and typical localities where 

 they are displayed, list of principal altitudes, etc. Mr. Stoddart 

 refers also to the igneous rocks developed in the neighbourhood of 

 Tortworth, on the Mendip Hills, and near Weston-super-Mare.

7. — Thomas, J. E. Prize Essay upon the Mineral Eesources of the 

 Counties of Flint and Denbigh, with suggestions for their de- 

 velopment. (Mold National Eisteddfod, 1873.) 8vo. pp. 41. 

 (Oswestry, 1873.) 



The author describes the geological features of the district, and 

 points out the mineral produce of each system of rocks. He then 

 considers the resources of Coal, Lead, and Zinc more in detail, 

 the extent to which they have been developed in this part of North 

 Wales, and their present yield, glancing also at the future supplies 

 that, it is to be hoped, may continue to be produced for many gene- 

 rations to come. In conclusion he gives a list of various collieries, 

 iron works, lead mines, brickworks and quarries in the two 

 counties. H. B. W.

 souri, 1855-1871. By G. C. Broadhead, F. B. Meek, and 

 B. F. Shumard. (Jefferson City, 1873.) 



THE publication of this volume appears to have been delayed, for 

 the maps were engraved, and the impressions contained in the 

 volume were struck off, previous to 1861, so that they do not 

 represent the present political geography of the respective counties, 

 and in some instances their boundaries have changed.
