as Scandinavia, where the Cambrian fossils have been so thoroughly 
worked out, is that between the district of S.W. and N.E. Scandinavia, 
where not only were the physical changes to some extent, distinct but 
occurrence or absence of the subfaunas was consequent upon these 
differences. 
Four superb plates of figures, chiefly of the new species and forms, 
add to the interest and usefulness of the volume. With this book in 
hand of those of Linnarsson, Brogger, Wallerius and others, one is 
able to get a very satisfactory understanding of the Cambrian species 
of the Scandinavian peninsula and islands ; including many species 
of Angehn, upon which much obscurity rested owing to imperfect 
figures and very brief diagnoses of the species in the "Paleontoligica 
Scandinavica." 
An English summary of the contents is bound up with this book.
