to become readily acquainted with tlie literature of the subject. 

 Special works, therefore, giving a periodical resume of the different 

 widely scattered publications are not only a great boon, but attest a 

 self-denying and laborious energy on the part of the respective 

 editors. In this country we have the valuable Geological Eecord, 

 edited by Mr. Whitaker; in Switzerland the Eevue geologique Suisse, 

 compiled by M. E. Favre; and in France the Eevue de geologie, 

 under the able direction of MM. Delesse and De Lapparent, and 

 which has now attained its fourteenth year. The present volume 

 (1878), compiled with the same care and arranged in the same 

 manner as the previous ones, comprises the various papers on 

 geological and the allied sciences printed during the years 1875 

 and 1876, besides which are inserted many useful private communi- 

 cations forwarded to the editors by different geologists, and also (as 

 in previous volumes) the analyses of rocks which have been under- 

 taken in private laboratories, or in those of the Ecole des Mines or 

 the Ecole des Fonts et Chaussees. The classification of the subjects 

 is adopted from the Manual of Geology, by Dana and arranged 

 under the five chief divisions of Physiographical, Lithological, 

 Historical, Geographical, and Dynamical Geology, special attention 

 being given by M. Delesse to the researches on rocks and their 

 nietamorphism. 



The editors have noticed the works of more than 400 authors, and 

 have given a concise account of their contents, noticing to a greater 

 extent those not published, in France. — J.M. 



II. — ViCTOKiAN Organic Eematns. — Prodromus of the Paleon- 

 tology OF Victoria. Decade V. By Prof. F. M'Cot, F.G.S., etc. 

 (Melbourne, 1877.) 



THE figures and descriptions of the new or more characteristic 

 Victorian organic remains of each formation are continued by 

 Prof. M-Coy in this fifth decade, which is, therefore, an assistance to 

 the field geologist in determining the approximate geological ages 

 of the various formations he may meet with. The present number is 

 of equal importance with the preceding ones, and contains illustra- 

 tions of fossils of much interest both to the Colonial and European 

 palaeontologist, for some of the species noticed of Upper Silurian 

 mollusca are identical with well-known abundant and characteristic 

 forms of Europe and North America, whilst others are representative. 

 So also with some Eocene forms, it is shown that the most careful 

 comparison is necessary to distinguish between species of Cardium 

 from the Tertiary strata of Australia and our own country. The con- 

 tents of this number are various ; the first two plates illustrate new 

 extinct species of Eared Seal [Arctocephalus Williamsi) from the 

 Pliocene strata of Queenscliff, and nearly related to the living genera of 

 the Southern Seas; the third, fourth, fifth, and ninth plates are devoted 

 to illustrations of some characteristic forms of Tertiary Mollusca, as 

 Waldheimia, Cardium, Spondylus, and Cyprcece; the sixth and seventh 

 plates contain many figures of Upper Silurian Brachiopoda. The 

 next plate illustrates a new spheroidal Tertiary species of Sponge,
