1862.] SANDBEEGEE HEMPSTEAD FOSSILS. 331 



and Alzey, — so that I now can no longer doubt that the upper beds of 

 Hempstead accurately correspond with our '* Marine Sand." 



Much more difficult is it to make out the lower beds ; I can at 

 present only point out one horizon which corresponds with anything 

 in Alsace or Germany — the freshwater limestone of Bembridge and 

 Sconce = beds at Buxweiler (Alsace) and Abstadt (Baden). Here 

 the following species are decidedly identical : — Helix Vectiensis, Edw., 

 H. JD'Urbani, Edw., H. occlusa, Edw., Planorhis rotundatus, Sow., 

 PI. oligyratus, Edw., PI. lens, Brongn., and PI. elegans, Edw. Un- 

 fortunately I have not the means of ascertaining whether the ana- 

 logies can be carried further. I am also disposed to believe that the 

 freshwater limestones of Castelnandary in France belong to the same 

 horizon, from whence I have received about twenty species from 

 Deshayes and Lartet. At the same time I cannot venture to con- 

 sider this so certain as the comparisons with Abstadt, and particularly 

 with Buxweiler (Dep, Bas-E,hin). 



The fossils from Headen Hill and Colwell Bay have no resemblance 

 with those of our " Marine Sand." They probably belong to the level 

 of Dumont's Tongrien Inferieur (Lethen and Westeregeln) and Ton- 

 grien Si(joerieur=:Marne sitperieur au gypse. It will be necessary 

 for me to compare the marine forms with those of Westeregeln and 

 Bernburg, from whence I am expecting a collection. But the com- 

 parison will at aU events be difficult, because the English beds are 

 almost entirely brackish, and the German are all purely marine ; it 

 will therefore be some time before I can give any account of them. 

 In the meantime it appears to me of great importance to be able to 

 point out an exact equivalent of the beds at Alzey and Buxweiler and 

 Abstadt, which, with the exception of the Bohnerz in South Germany, 

 are the only representations of the Lower Oligocene.

1. On the Metamorphic Rocks of the Banfeshire Coast, the Scara- 

 BiNS, and a Portion^ of East Sutherland. By R. Harkness, 

 Esq., E.R.S., F.G.S., Professor of Geology and Mineralogy,

Introduction. — I am not aware of any memoir which has reference 

 to the metamorphic rocks of Banffshire, save that of Mr. R. J. H. 

 Cunningham, published in the ' Transactions of the Highland and 

 Agricultural Society of Scotland ' (vol. xiii.). In this memoir there 

 is a great amount of information concerning the lithology of the 

 rocks which compose the metamorphic strata of this portion of
