568 RevieiDs — F. Ameghino's PyroiJierium-heds. 



Mr. Morton bas continued to add to the general stock of knowledge 

 on all these points ; and the Appendix (pp. 293-319) indicates, 

 among other things, an extended acquaintance with ice-scratched 

 surfaces at and near Liverpool. These local "glacial striae" were 

 more pi'obably (p. 302) made by " bergs and pack-ice," " brought 

 by the wind and tides from the north and north-west over the 

 low-lying Triassic rocks of South- West Lancashire and Wirral," 

 than by " the action of an enormous glacier, of which there is no 

 probable evidence." Further notes and particulars about the erosion 

 on the coasts, especially at the Leasowe on Wirral, are communicated ; 

 as well as the results of Mr. Morton's careful research as to the range 

 of species in the Carboniferous Limestone of North Wales.

V. — Appendix to the Geology of the Country around Liver- 

 pool, with a Geological Map of the District. By G. H. Morton, 

 F.G.S. 8vo, pp. 293-319. (Liverpool: George Philip and 

 Son, 1897. Price, 4s. 6d) 



rriHIRTY-FOUR years have passed since the first edition of Mr. 

 X Morton's well-known work on the GeoL)gy of Liverpool was 

 published. A second edition was issued in 1891, and now the more 

 recent researches have rendered desirable an Appendix. The map, 

 which is printed in colours, shows very clearly the distribution of 

 the various formations, exclusive of the mantle of Glacial Drifts. 

 It is based on the work of the Geological Survey, but contains 

 important additions and revisions. The term " Pebble-beds " of the 

 Bunter is replaced by that of the Upper and Lower Hard Sandstone, 

 because in Cheshire and South-West Lancashire scattered pebbles 

 only occur in the lower beds, and they are absent altogether from 

 the upper portion of the series. The total thickness of the Keuper 

 Marl is now known to be 1,000 feet. Three plates illustrating 

 remains of Cheirothermm are added. The author gives further notes 

 on the range of species in the Carboniferous Limestone of North 

 Wales ; and he contributes particulars relating to the erosion of the 

 sea-coast, glacial strias, and recent deep borings, 



VL — Flokentino Ameghino. La Argentina al traves de las 

 ultimas epooas Geologicas. Disertacion pronunciada en el 

 acto de la inauguracion de la Universidad de La Plata (18 de 

 Abril de 1897). (Buenos Aires, 1897.) 



THE present lecture, delivered on the day of the inauguration of 

 the La Plata University, covers the same ground as a former 

 paper by the author, of which a translation was published in this 

 Magazine;' so that Mr. Smith Woodward's remarks accompanying 

 the translation apply on the whole to the present paper as well. 

 What is new are the text-figures, accompanied by very short 

 characteristics of the oldest hitherto known Mammalian fauna of 

 Argentina, from the Pyrotherium-heds. The figures are taken from 

 the author's forthcoming memoir in vol. xviii of the Boletin del 

 1 Geol. Mag., Dec. IV, Vol. IV, 1897, pp. 4-23.
