seven stages or terraces faintly marked, formed of marine pebbles 

 placed one behind another and separated by turfy soil. The whole 

 of this system, he says, rests npon a thick layer of the debris of 

 shells, among which we perceive fragments of Cyprina islandica and 

 other molluscs, identical with those now living in the Polar ocean. 

 It is the same with regard to the Island of Qualse, and we have 

 there an additional curious point, namely, his discovery in a depression 

 behind the gate of the town of Hammerfest, and at a height of about 

 82 feet above the sea a number of erratics, the interstices between 

 which are filled with small pieces of blackish pumice-stone, similar 

 to those wliich continue to be thrown ashoi'e from time to time, even 

 in the present day, on the coast of Norway, along with floating 

 wood, whose origin is evidently to be assigned to the volcanic 

 eruptions of Iceland, or of that of Jan Mayen (Chambers, Sea 

 Margins, pp. 286-7). 



Bravais ("Former Sea-level in Finraark " : Q.J.G.S., i, p. 544, 

 1845) points out how in Finmark the shell beds occur at a much 

 lower level than further south. At Talvig, by digging about half 

 a metre below the surface in a sheltered part <Ji the bay, he laid 

 open a clayey bank containing 2fya truncata and Tellina BaltMca, 

 some of the specimens being remarkably fresh and even showing 

 vestiges of the epidermis. This bed "was 7 metres only above the 

 sea-level and appeared identical with one described by M. Keilhau. 

 "I have likewise," he says, "received other shells {Patella and 

 Venus) collected near Storvig, at the western extremity of the Island 

 of Soroe, in a sandy deposit a few metres above the level of the sea. 

 The elevation in this case was about 30 metres." 



A similar drop in the shelly beaches has been noticed in pro- 

 ceeding southwards from Trondhjem, showing that the movement of 

 the land in Western Norway (as in Sweden) has been differential, 

 with a culminating point at Trondhjem.

lY. — The Stkatigeaphical Position op the Cokalline Ckag. 

 By F. W. Hakmer, F.E. Met. Soc, F.G.S. 



N an interesting paper lately published^ my friend Mr, E. B. 

 Newton has expressed the opinion that the Coralline Crag 

 should be grouped with the Diestien and Anversien of Belgium as 

 Upper Miocene, the fauna of the Suffolk boxstones being regarded by 

 him as Middle Miocene. The recent I'esearches of Mr. Alfred Bell ^ 

 have led me to agree with Mr. Newton that the latter is pre-Pliocene, 

 but I regret I cannot accept his view as to the age of the Coralline 

 Crag, which I consider to be more nearly related to the Waltonian 

 horizon of the Red Crag than to the Belgian Miocene.

 Great Britain, now in course of publication (pt. i, p. 5), I proposed
