•Crustacea," drawn by J. W. Salter, F.G.S., and Henry Woodward, 

 F.E.S. ; a few are from Ramsay's " Physical Geology." They are 

 very well selected, and will serve to illustrate the forms of the 

 leading fossils that are to be met with in the various British 

 stratified rocks. 



The maps in the original atlas were based to a large extent on 

 those published by the Geological Survey, and they have now 

 been revised, as far as the scale has permitted, from the later 

 published maps of that institution and from Sir A. Geikie's 

 Geological Map of Scotland. The work reflects credit on both the 

 author-editor and publisher, and deserves to prove a success, and 

 is certainly a very useful addition to our geological library. 



III. — A Guide to the Fossil Mammals . and Birds in the 

 Department of Geology and Paleontology, British 

 Museum (Natural History), Cromwell Road, London, 

 S.W. Eighth Edition. 8vo ; pp. xvi and 100, with 6 plates 

 and 88 text-figures. (London, 1904. Price 6c?.) 



rnHE Guides to the Geological Department bid fair to continue 

 JL to be "the cheap sixpenn'orth " of the Museum. The 

 aggregate sales of the seven earlier editions (1881-1896), we ai'e 

 told, amounted to about 20,000 copies ; and we may safely prophesy 

 that the one issued this year will find equal favour with the public. 



This work has been entirely rearranged and rewritten ; 28 of 

 the text-figures used in the earlier editions have been withdrawn, 

 and 14 new text-figures introduced, 5 octavo plates of fossils, 

 a new geological table of fossiliferous deposits giving British 

 and European names of strata, also a folding plate-plan of the 

 Mammalian and Avian Galleries. 



The new illustrations comprise two views of the same block of 

 a Lower Pliocene Bone-bed from Pikermi (near Athens), obtained 

 by Dr. A. Smith Woodward, F.R.S.,^ together with a large 

 collection of fossil remains in 1901 (see Geol. Mag., 1901, 

 pp. 481-486), crowded with bones of mammals and of birds. The 

 three-toed Horse (Hipparion), various bones of antelopes, and some 

 carnivora make up the great mass of the block. 



A block of flint from Crayford, Kent, broken by Palgeolithic man 

 in making flint-knives, is illustrated on p. 7 as one of the prehistoric 

 series. The restored skull and mandible of the giant lemur, 

 Megaladapis insignis, from a cave in Madagascar, is drawn (p. 11), 

 and the gaping jaws and outline of head of the sabre-toothed tiger 

 (Machcerodtis) (p. 13) from South America. After such a yawn, 

 do you think he could ever shut his mouth again ? The skeleton 

 o^ Hymnodon from Dakota (p. 16) is also new. 



Of wonders added to the collection lately is the skull and 

 mandible of Arsinoitherium zitteli (fig. 38, p. 47), a mighty 

 herbivore of the new order Barypoda (see Dr. C. W. Andrews, 

 •Geol. Mag., October, 1904, p. 481), from the Upper Eocene of
