is still in part, mantled by Miocene formations. The disjointed 

 faulted and elevated blocks of this ancient coastal plain show 

 that the old land owes its present comparatively great elevation 

 not so much to the original folding as to bodily secular move- 

 ments since the Miocene period. Narrow coastal belts, hardly to 

 be called coastal plains, stand between the uplands and the sea.

6. Om Flacldale og Randmorcener i Jylland ; af N. V. 

 Ussing. Resume Sur les Alluvions Glaciaires et les Moraines 

 Terminates en Jutland • K. Dansk. Videnskab. Forhandlinger, 

 1907. No. 4. Pp. 53 and pi. 1.— This paper deals with the 

 moraines of recession in Jutland and their outwash plains. The 

 outermost of these was formed during a prolonged period of 

 arrest named the Baltic epoch of arrest. The later recessional 

 moraines present a much younger appearance. A resume in 

 French is given at the end. j. b. . 



7. Die Alpen im Eiszeitalter ; von Dr. Albrecht Penck 

 und Dr. Edtjard Bruckner. Part 8, in two sub-parts, pp. 

 785-896. Leipzig, 1907 (Chr. Herrn. Tauchnitz). — It is announced 

 that this work is to include ten parts and that it will probably 

 be soon completed. In part 8 the Pleistocene history of the 

 Lombardy Alps is treated with the same clearness and thorough- 

 ness which have marked the study of other sections of the Alps 

 by these authors. The older and younger moraines are separated 

 and the outwash plains and terraces are also mapped. The 

 glaciated and non-glaciated positions of the Alps are discriminated, 

 allowing the profile of the former glaciers and the snow line of 

 glacial times to be restored. The inter-glacial deposits are also 

 studied. j. b. 



8. Revision of the Pelycosauria of North America • by E. 

 C. Case. Carnegie Institution of Washington, Publication No. 

 55. Quarto, 1 76 pages, 35 plates and 73 text-figures. — This impor- 

 tant monograph deals with the Permian suborder Pelycosauria 

 and is based mainly upon the collections preserved in the Amer- 

 ican Museum of Natural History collected by Professor Cope and 

 by the author himself, as well as upon two collections made by 

 the latter for the University of Chicago. 



Following the introduction there is an historical review of the 

 Pelycosauria in which former classifications are discussed. The 

 next section is given to a systematic revision of the suborder, 

 which includes, according to Case, three families, seven genera, 

 and 18 species. The morphological revision gives one an admira- 

 ble idea of the peculiarities of this remarkable group, which 

 contains some of the most bizarre and grotesque of reptiles. Occa- 

 sional restorations of the skeleton throw a great deal of light 

 upon the proper interpretation of the remains. In summing up, 

 Case tells us that the Pelycosauria constitute a highly specialized 

 and short-lived branch from the beginning of the Rhynchocepha- 

 lian stein, a striking example of rapid evolution to extreme spec- 

 ialization from very primitive and generalized conditions. In
