Mr. H. Hicks and Mr. J. W. Sarter.—The results of these researches 
have led to the discovery of an entirely new British formation, and the 
authors propose a new term for the group. The district of St. David's 
Was anciently called “Minevia,” and hence, following the example of 
the best geologists—viz., first to ascertain the position, then the fossil 
contents of a group, and then to name it—the authors propose the te 
“Minevian” for the lowest division of the “ Lingula flags.” Mr. Hicks 
described five sections north and south of St. David’s—the coast afford- 
sections show a passage from this group into the Ffestiniog group of 
Professor Sedgwick, which forms the main mass of the “ Lingula flags 
group and the Llandeilo flags of the sections has shown foss 
traces after a lon persevering search. But the section at Porth 
aw is not only the typical one, but contains all the principal fossil 
iopod and 
ent kinds. All of them are distinct not only as to species, but — 
tell the true horizon of the gold-bearing rocks of Wales 
tify accurately the oldest fossil-bearing strata of Bohemia and Sweden 
created, as these last were long anterior to the very earliest of the fishes. 
With regard to the distribution of the fossils themselves, the lo 
which actually lie among the uppermost coarse beds of the Cambrian 
grits, only distinguished from them by the want of purple color, contait 
a species of Paradorides (P. Aurora), with which are associated 80 
minute Trilobites, Agnosius, Microdiscus, &c. Farther up we have Par- 
adowides again, but of a distinct species and larger, The mass <
