Invertebrata of France 



Fauna de France. Thysanoures, Myriopodes, Arachnides, Crustaces, Nemathel- 

 minthes, Lophostomes, Vers, Mollusques, Polypes, Spongiaires, Protozoaires. 

 By A. Acloque. 1664 illustrations. 18°, pp. 500. Paris : J. B. Bailliere et Fils. 

 Price 10 frs. 



This is the third volume of Mr Acloque's Fauna of France, Coleoptera 

 appearing in 1896, Orthoptera and the remainder of the insects in 

 1897. We are promised a fourth and last volume to contain the 

 Vertebrata and Tunicates. We are also indebted to the author for a 

 flora which appeared in 1894. Acloque takes his subject genus by 

 genus, giving a brief diagnosis of each of them, then following on with 

 the species recorded from France, he similarly gives short diagnoses and 

 localities. The numerous figures are sketchy, but no doubt charac- 

 teristic and useful for identification. There is room for a book on this 

 plan dealing with the English fauna. 



Bibliography of Mexican Geology 



BlBLIOGRAFIA GEOLOGICA Y MlNERA DE LA RePUBLICA MEXICANA, FORMADA PAR 



Rafael Aguilar y Santillan. 4°, x + 158 pp. Mexico: Oficina tipografica de 

 la Secretaria de Fomento. 1898. 



Dr Rafael Aguilar deserves hearty thanks for this excellent and 

 compendious Bibliography. No less than 1953 items in the geology 

 of Mexico are sufficient to appal anyone who knows the weakness of 

 our London libraries on special subjects of this kind. The list is 

 arranged in double columns, under authors in alphabetical order, while 

 the last eight pages are devoted to indexes of the principal localities 

 cited and of the more important matters. It is well and clearly 

 printed and will be a great accession to all geological libraries and 

 students. 



Bibliography of Westralian Geology 



The first Bulletin of the Geological Survey of Western Australia, is 

 devoted to a Bibliography by Mr A. Gibb Maitland. Mr Maitland, 

 who was formerly on the Geological Survey of Queensland, has 

 arranged this under authors, and like so many of these useful works 

 it was originally compiled for his own convenience. Mr H. P. 

 Woodward, his predecessor, assisted Mr Maitland with a list of works 

 extracted from the catalogues of the British Museum. As the Biblio- 

 graphy contains Papers, Reports, and Maps bearing upon the 

 Mineralogy, Mining, Geology and Palaeontology of Western Australia, 

 we need not refer further to its importance. 



Dr Chas. Davison hopes to publish, with Messrs Cornish of Birming- 

 ham, a volume on the Hereford Earthquake of December 17th, 1896, 

 provided that a sufficient number of subscriptions be obtained to 

 ■cover the cost of its production. 



This earthquake was one of the most important ever recorded in 

 this country. Though inferior to the Essex earthquake of 1884, with 

 regard to the damage done to buildings, its disturbed area was at least 

 twice as great, being not less than 100,000 square miles. It was felt 

 in every English county, except the three northern ones, over the 

 whole of Wales and the Isle of Man, and in the eastern counties of 

 Ireland. The number of observations on which the discussion is
