384 NATURAL SCIENCE. Nov.. 



montanus ; Phasianus colnmbianus ; Tetrao fusca ; Sterna Philadelphia ; 

 Larus delawarensis ; Anas colnmbianus. The reptiles given in "Amphibia " 

 under new names are, Professor Cope says, " either synonyms or 

 unidentifiable." Mr. Rhoads has pubhshed in the American Naturalist, 

 June, 1894, PP- 523-526, a summary of changes in nomenclature 

 proposed, and to this the critical reader is referred. 



A few errata are carefully inserted on p. 52, and an index of over 

 4,000 entries enables ready reference to any names used either in 

 Ord's work or Rhoads' appendix. C. D. S. 



Deep-Sea Deposits. 



Carte des Sediments de Mer Profonde, avec notice explicative. By John 

 Murray and A.-F. Renard. 8vo. Pp. 45 and map 43 by 25 cm. Bruxelles : 

 Societe Beige de Librairif. (Societe Anony me), Oscar Schepens, Directeur, 16 

 rue Treurenberg, 1894. Price 2 fr. 50. 



Those who are fortunate enough to possess the first number of 

 Natural Science will find therein a long review of the " Challenger" 

 Report on Deep-Sea Deposits. The pamphlet now before us is 

 practically an epitome of the contents of that volume by its authors, 

 and is published so as to bring within reach of all the main facts and 

 results detailed in the Report. 



The text appended to the present map, which appeared originally 

 in the Bulletin de la Societe beige de geologie, vol. viii., 1893, consists 

 of a concise summary of the various types of sediment distinguished 

 by the authors, exclusive of the micrographical and chemical details 

 and theoretical considerations provided in the bulkier Report. It 

 presents all the facts on which are based the construction of a sub- 

 marine geological and mineralogical map. 



The descriptions commence with the nature of the deposit (red- 

 clay, blue-mud, globigerina ooze, radiolarian ooze, etc.), and follow 

 v/ith a general determination of the macroscopic characters of the 

 deposit. The sediments were treated with hydrochloric acid, and 

 both the soluble and organic contents are given. The residues, after 

 washing, were sorted into three groups, which are given under the 

 headings of Siliceous organisms. Minerals (particular minerals and 

 rock fragments), and Amorphous matter. 



The pamphlet concludes with a chapter on the geographical and 

 bathymetrical distribution of deep-sea deposits. The map, which is 

 clearly coloured, shows at a glance the depths of the oceanic areas in 

 brasses (100 brasses =183 metres), the lines of depth being drawn at 

 100, 500, 1,000, 2,000, 3,000, 4,000, and deeper than 4,000 brasses; 

 and the deposits are coloured and defined as muds and coral sand, 

 globigerina ooze, diatomaceous ooze, radiolarian ooze, pteropod 

 ooze, red clay, and blue muds. 



The information about deep-sea deposits thus presented in so 

 convenient a form cannot fail to be of the greatest service. 



The Fisheries of the Mediterranean. 



Les Pecheries et les Poissons de la Mediterranee (Provence). By Paul 

 Gourret. i6mo. Pp. 360 with 109 figures. Paris: J. B. Bailliere & Sons, 

 1894. Price 4 fr. 



This little work, by the sub-director of the Zoological Station at 

 Marseilles, forms a volume of Messrs. Bailliere's Library of Useful 

 Knowledge. It is an interesting treatise on the fishes and fisheries of
