Gaateropods. 



Bellerophon : common, (The fragments agree with the form which 

 is abundant in the upper part of C in the fact that, whereas the 

 young stage exhibits a sulcate periphery, the adult is strongly 

 keeled.) 



CORKELATION. 



Were such a faunal assemblage as that cited above met with in 

 the South-Western Province, the level at which it occurred would 

 unhesitatingly be referred to the top of the Syrmgothjrls zone and 

 the bottom of the Seminnla zone (Cj-Sj), that is, to the middle of 

 the Avonian sequence. This correlation does not rest solely upon the 

 close similarity of the Corals and Brachiopods to forms which 

 characterize the Cg-Si level in the South-Western Province, for the 

 conclusion is confirmed by the absence of any Brachiopod or Coral 

 which is known to be confined to higher levels. Assuming, then, that 

 the above correlation is correct, the conglomerate at the base of 

 Ingleborough was deposited at the same time as the conglomerates of 

 Pendine^ (north of Tenby) and of Rush ^ (co. Dublin). 



Hence we owe to Mr. Cosmo Johns a new and an important 

 page in the history of the widespread Mid-Avonian movement.

I. — The Face of the Earth. By Edward Suess, Professor of 

 Geology in the University of Vienna. Translated by Hertha 

 B. C. SoLLAS, Ph.D., of Newnham College ; under the direction 

 of Professor W. J. Sollas, LL.D., F.R.S., etc. Vol. ii. 8vo ; 

 pp. vi, 556, with 3 plates, and 42 other illustrations. (Oxford :

IT is a privilege for which many of us cannot be too thankful, to 

 be able to read in clear and well-chosen language the story 

 unfolded by Suess of the physical history of the Earth. We drew 

 attention in the Geological Magazine for May, 1905, to the 

 translation, by Dr. Hertha Sollas, of the first volume of " Das Antlitz 

 der Erde " ; we have now the satisfaction of notifying the publication 

 of the second volume. The previous work, divided into two parts, 

 dealt with the Movements in the Outer Crust of the Earth, and with 

 Mountain Ranges. The present work (part 3) deals with the Sea. 

 The subject is introduced to us in pleasant, not to say poetic language : 

 " We have descended from the mountains and stand on the sea-shore. 

 The eye I'oams unchecked over the vast expanse of waters. A great 

 wave approaches and seems about to reach us ; suddenly its crest 

 ourls over, it plunges downwards, and with a dull roar sweeps a 

 little further on without wetting our feet. Then the water streams
